Types of chart patterns detected by ATmatix

Just a few words about the way ATmatix detects the patterns and the types it supports.

A chart pattern is nothing more than a unique scheme of price tops and bottoms that appear in a certain finite period of time. Those tops and bottoms are just local maximums and minimums created by the asset price behavior.

To make things short – for instance, double bottom consists of two local minimums divided by a certain minimal number of sessions, in between which there is some local peak (additionally the rise from the lowest bottom to the peak can’t be too small). Of course, it’s not everything, because to talk about a bottom, the pattern must be preceded by a certain descending trend. The trend’s reversal is often - but not always - preceded by the creation of a bottom pattern.

A huge part is played by the parametrization of our pattern recognition algorithms. We will try to put those parameters on the ATmatix website in the future. For instance, we assumed that the rise from the first bottom to the local maximum between two valleys in a bottom pattern should be at least 5% for stocks and at least 2% for indices and futures.

Some patterns form specific shapes, such as triangles, channels, wedges, etc. Those patterns usually have two limiting trendlines. Breakout occurs when a stock price pierces one of those trendlines in a certain direction. For example, a channel pattern consists of two parallel trendlines next to each other (more or less in the same time) in the price chart and the price bounces from the bottom to the top line and back few times. Those trendlines are the breakout levels. Their slope indicates the type of the channel (horizontal, descending or ascending).

ATmatix detects trendlines in the following way: it looks for two points, being local minimums (in case of the lines limiting the pattern from the bottom) or maximums (in case of the lines limiting the pattern from the top) and a third point located between them - which doesn’t have to lie exactly on the line between those two points (there is some tolerance, without it we wouldn’t be able to find many). So, basically to set the line, you need three points. Sometimes, the technical analysts base the trendline using two points only, but there would be many of such lines found, and in our opinion minimum of three point sounds like a reasonable compromise between the large number of signals (sometimes false positives) and the risk of “overlooking” some signal due to a trendline occurrence.

Currently, ATmatix is able to detect price chart pattern types gathered below. The list is going to be gradually developed.

Bottom patterns:
  • Double bottom,
  • Head and shoulders bottom
Top patterns
  • Double top,
  • Head and shoulders top
  • Triangle, symmetrical triangle
  • Descending triangle
  • Ascending triangle
  • Descending channel
  • Ascending channel
  • Horizontal channel
  • Falling wedge
  • Rising wedge
  • Flag
  • Pennant
Broadening formations:
  • Broadening triangle (inverted triangle)
  • Descending broadening triangle (descending inverted triangle)
  • Ascending broadening triangle (ascending inverted triangle)
  • Descending broadening wedge
  • Ascending broadening wedge
Other, special types of patterns or price schemes:
  • Flat base
  • Vertical run up
  • Three rising valleys
  • Support
  • Resistance
  • Uptrend
  • Downtrend

At one point ATmatix was able to detect also a diamond pattern, but it is such a rare occurrence on Warsaw Stock Exchange that we have dropped it (the statistics wouldn’t be realiable at all).

Why does ATmatix not detect so-called candlestick patterns (hammers, shooting stars, etc.)? Firstly of all, we find them not helpful – how can you predict price movement based on one (sic!) or even a few candlesticks on the chart? Maybe it’s realiable for the weekly or longer interval charts. For us, those signals are insignificant with long-term investments – but we would emphasise it – it is just our opinion.

Secondly, many candlestick patterns’ scanners can be found accross the Internet. As we have already mentioned, the creation of ATmatix was sort of a technical and algorithmical challenge for us, slightly bigger than recognizing simple candlestick patterns.

The states of the patterns

The price patterns, since they are identified by ATmatix, until reaching the target price (or maybe not) in a certain period of time, may be in a few states (or statuses). All of them are described below.


When ATmatix detects a new pattern, it finds all the local peaks and valleys within the pattern. On the chart, they are marked as green or red arcs. Additionaly, for some types of patterns, those points in charts are connected with a blue dotted line, as it is easier to observe some price movement schemes.

Every pattern has its starting point (the first, the earliest local peak or valley, which could be identified) and the end-point (the last peak or valley). The end-point is also a date of pattern detection, presented in the pattern list view.

At the time of the detection, two levels of breakout are determined (trendlines limiting the pattern from the top and bottom):
  • Downward breakout level (red line)
  • Upward breakout level (green line)

For some linear patterns, where breakout levels are inclined at an angle (triangles, wedges, channels, etc.), some fragments may be marked with solid lines, as it is easier to observe the shape of a pattern; other fragments may be marked with dotted lines.

A solid line is used within a pattern area (between the starting point and the ending point) and the dotted line is just an extension of that line outside the pattern.

It is intresting to notice that for some linear patterns, the breakout lines, inclined at an angle, get closer to each other and converge at some point.
It happens, for instance, in case of triangles or pennants. Then, the intersection point becomes the last moment, where the breakout is possible.
More on breakouts can be found below.

Certain values characteristic of the pattern are calculated immediately after its detection. Those are:
  • The width of the pattern (the number of sessions, or candlesticks in chart, between the starting point and an end-point),
  • The height of the pattern (the percentage difference between the highest and the lowest price value within the pattern),
  • The potential of the pattern (expected percentage price change to the hypothetical target, assuming there were an upward breakout on the day of its detection). After the actual breakout, the potential is calculated again. More information below.
  • Volume trend – the approximation of the turnover volume value from the starting point of the pattern to its endpoint, determined by the linear regression method. The slope of this approximated line may be falling or rising. 
  • Breakout statistics – based on the pattern type and the historical data. Please, note that these statistics may not add up to 100%. 

The statistics are calculated in this way:
  • In case of an upward breakout, the occurrence is counted as the upward breakout (nevermind throwbacks)
  • In case of a downward breakout, the occurrence is counted as the downward breakout (nevermind pullbacks)
  • In case of the upward breakout and then throwback, not reaching the target price, and then downward breakout (or the other way round), the statitistics take into account the move that was stronger after one of the breakouts
  • No breakout at all – often it happens with triangles, whose area is bounded by two approaching lines. Also the time span ATmatix waits for a breakout, is limited.
New, emerging double bottom pattern - example

What time does ATmatix wait for a breakout?

What time does ATmatix wait for a breakout, so that it could detect it and inform about it? It depends on the width of the pattern.

I have already mentioned the triangles or pennants – if the breakout (upward or downward) doesn’t occur within the pattern, then the breakout will not be detected by ATmatix (and will be counted as no breakout, which is why the upward/downward breakout statistics not always add up to 100%). Obviously, the price may choose a particular direction after some time, but it couldn’t be confirmed with a breakout within the pattern area.

It is slightly different for the patterns for which the breakout levels are constant values (for instance double bottom) or lines not expected to cross in the future (i.e. channels, broadening patterns).
Then the breakout time limit since the detection date is: the width of the pattern (number of sessions), but not less than 60 sessions.

For example, for double bottoms 30 sessions wide, we wait 60 sessions for the breakout, and for a double bottom 80 sessions wide, we wait 80 sessions.


If the price approaches an upward breakout level from the bottom, or approaches a downward breakout level from the top, but not pierces it, then ATmatix marks it as “near breakout” (upward or downward). Those occurrences are detected with some tolerance. For the constant (horizontal) levels the tolerance is 2.5% for stocks and 1% for indices/futures.

Some additional conditions apply:
  • For “near upward breakout” – there has to be no decline on that day – the price hasn’t changed or has risen, reaching almost the upward breakout level with the tolerance as mentioned above,
  • For “near downward breakout” – there has to be no rise on that day – the price hasn’t changed or has declined, closing to the downward breakout level with the tolerance as mentioned above.
For example, the stock closing price on a given day must be at least 2.5% below the level of the upward breakout (and it can’t be a declining move). It is a bit different with patterns limited with non-horizontal trendlines. The lines may approach each other (triangles), get farther from each other (broadening patterns) or be parallel (channels). Then the area between the upper and lower trandline – on a given day – is divided into 4 equal parts. If the close price on that day, is in the highest or lowest quarter, and when the above conditions are met (decline, rise or no change), the event “near upward breakout” or “near downward breakout” is detected.

It is essential to notice that if the price will make the breakout with one-day strong movement, then the “near breakout” event may not be detected at all.
That can be also signalled a few times, when the close price of a stock approaches the near breakout area several times during the following sessions.
Those occurrences are marked in the charts with yellow arrows, next to which a close price and an event date are given.

The pattern is close to the upward breakout - example


A breakout happens when the price pierces upper or lower level of the breakout (goes through the trendlines limiting the pattern) on a given day.

The pierce of the constant breakout level is detected in case when the close price exceedes the level even by a penny. In case of linear breakout levels (leaning at some angle) the breakouts are detected with some tolerance.
It happens because the detection of trendlines itself works with a certain tolerance (the lines may not lay perfectly on the three selected points in the chart and the line may in general be based on different point combinations –  give a technical analyst a task to draw the trendline and you’ll know what I mean).
For this reason, piercing the trendline by even the smallest margin, could result in a false breakout – this is why we have set up some tolerance.  Additionaly it’s good to observe the turnover volume on the day of the breakout.

Currently, the tolerance is 0.55% for stocks and 0.32% for indices/ futures. The values were empirically selected as a compromise between large number of possibly false positive signals and their validity.
Usually the price volatility for indices/futures are rather smaller than for stocks, which is why we have decided to divide the list of instruments into two groups, and for each of them some parameters of the pattern scanner are different (the statistics are alsbo calculated separately for stocks and indices/futures).

Other values caltulated after the breakout are:
  • Breakout price – the level, for which the breakout occurred. Price targets are calculated in relation to this level (with a rare exceptions, such as flags and pennants)
  • Potential – the value is updated according to the direction and price of the breakout. It comes right from the target price computed with a measure rule for a given pattern type (explained below). The values less than zero mean that a certain decline is expected
  • Turnover volume on the day of the breakout – this is a relative value, comparing the turnover volume with the average volume from 30 pre-breakout sessions. It is a percentage, where value below 0 shows that the volume was smaller than the average, and the value above 0 means the volume was greater than the average.
The pattern breakout is either a confirmation, or the negation of its validity. In case of the bottom pattern – its confirmation is an upward breakout. If the bottom pattern had a downward breakout then it’s not the bottom any more, because the price has declined even further. It is then an invalidation of such pattern. Similar things happen in the case of top patterns and upward breakouts. However, it doesn’t mean that it is impossible to try to predict the hypothetical target price after such breakout. ATmatix can handle it as well - we will post some information about it in the future.

In case of pattern types commonly regarded as “continuation” patterns, it is hard to speak in terms of pattern confirmation or invalidation, so the breakout direction usually (but not always) means the direction of the preceding price trend is sustained.

The upward breakout - example

The most important data – target prices – are calculated after the breakout. They are presented with the statistical efficiency rates of such breakouts, based on the historical data. Please remember that any historical data does not guarantee you will get the same outcome in the future, but they are a good (and the only reasonable and available) reference when estimating risk of success or failure.

Usually, the target price (we can treat it also as a take profit level after an upward breakout or the purchase opportunity after the downward breakout move is completed) is measured by adding the absolute value of the height of the pattern to the breakout price – there are some exceptions to that rule, but I will dwell on it some other time.

These are the theoretical breakout levels and the description of their measure rules may be found in many books and across the Internet. I emphasize that such theoretical levels are not always specified. The specialized literature often says nothing about calculating targets after the downward breakout for bottom patterns or the upward breakout for top patterns.

The unique feature of ATmatix is calculating one more target level, based only on the historical data of the patterns. Those statistics allow us to compute, first of all, the effectiveness of the theoretical measure rules (the percentage of reaching the targets in the past), and secondly, they allow us to set the target level with a certain value of probability (based on the historical data).

Because it is a highly complex matter, and probably the most important for the application, I will describe it in detail in some other posts.

For now, to sum it up – ATmatix sets the target range of two values (from – to):
  • Theoretical level (and presents the effectiveness of reaching it in the past) – it is not always possible to calculate it – i.e. it is missing in case of the downward breakout form the bottom pattern – as I’ve mentioned it above,
  • The statistical level (reached with certain probability, based on historical data) – this level is always calculated. The exception is when we don’t have the statistics for a certain type of pattern or our data sample is too small. 
A lower level of the two is always given as the first. If any breakout level will be 0 or less – which can happen for the low value stock and the downward breakouts – obviously such value is not presented.

ATmatix also displays the expected percentage price changes related to the breakout price (this is the potential of the price change). Let’s remember that these are the values calculated with the assumption of the perfect trade and there is no guarantee of achieving such results. We often fail to buy the stock exactly at the breakout price and sell them right at the target price, and the profit will be reduced by the transactional costs.

Nevertheless, we know what to expect and whether the transaction made on the basis of one, certain pattern, will be more or less profitable, more or less risky than for some other pattern – thanks to the calculated target levels and statistics gathered by ATmatix.

One more thing – there may be some situations in which the breakout goes one direction, the price doesn’t meet the target price, then there is a throwback (or pullback) and the price breaks out in the opposite direction.
Then we can say the pattern is busted. ATmatix detects only two breakout occurrences in different directions - after the breakout, there may be a reversed one. In such case, the target levels are adjusted accordingly.

In case of the third change of the breakout direction (the third breakout directed opposite to the second breakout and in the same direction as the first one), such situation is not being detected. Those cases (multiple pattern busts) are rather rare, but of course still possible.

Those breakout events are labeled with green or red arrows in the charts, depending on the breakout’s direction. Next to the arrow, you can see the closing price and the breakout date (month and day).


When the asset price after the breakout reaches at least the predicted target range, the pattern is completed. Certain conditions have to be met:
  • After the upward breakout, the high price on a certain day has to reach the value greater than or equal to the lower level of the target range
  • After the downward breakout, the low price on a given day has to reach the value lower than or equal to the upper level of the target range
Sometimes the price target is met on the same day the breakout had occurred (if the price movement was strong enough to reach it and the target level is near the breakout level) and obviously ATmatix signal both events on the same day.

The time limit for meeting the price target, since the day of the pattern detection is currently set to 90 sessions, regardless of the width of the pattern.

In the charts, those occurrences of pattern completion are labeled with blue arrows. Next to the arrow, there is the low or high price on the event day (depending on the direction of the breakout).

The stock price reaches its target after the breakout - example


Irrespective of reaching the target price in a certain time limit or not doing so, ATmatix tracks each pattern for some period yet.

So, after some time since the pattern completion or since ATmatix has stopped tracking the pattern, its data is deleted, but it is obviously included in our historical stats.

Email notifications

ATmatix is able to send you email notifications about patterns and other events detected. This option is available for PREMIUM users only (just a quick reminder, registering a new account gives you 15 days of PREMIUM account trial period for free).

Email notifications inform you about:
  • Newly identified price patterns (patterns that are emerging, but not yet confirmed with a breakout),
  • Patterns close to an upward or downward breakout (which may result in actual breakout and a further move in the direction of the breakout or changing the direction of the movement and bouncing back),
  • Patterns with breakouts,
  • Reaching predicted price targets, previously set by ATmatix after breakouts.

Specific stages of the patterns’ lifecycle (from their detection to completion) will be discussed in another blog post.

The email notification you get, obviously does not include all patterns or events from the day (or week), but is narrowed to the most important ones, which have the biggest potential – the largest expected rise (or decline, depending on the direction of the movement).

Defaultly, the notifications are enabled. To disable them or to change their frequency, you have to log in, go to the account settings page, by clicking your email address in the right upper corner of the screen or by choosing the “Account” option available in the dropdown menu (such as it is done in the picture):

Then, in the “Notifications” section you can disable or enable the option “I would like to receive notifications”, and specify both the scope of data and the frequency of the notifications.

The "data scope" list has two options:
  • All – the user will be informed about all the detected pattern occurrences and events happening on the instruments tracked by ATmatix,
  • Watchlist only – the user will be notified only about events detected for assets added to their Watch List. The Watch List is visible for logged-in users in the patterns table page. The table and Watch List usage tutorial can be found here.
Available notification frequencies:
  • Daily – notifications are sent once a day, after each trading session ends (with a slight delay), and it includes the events from the last (current) session.
  • Weekly – once a week, sent after the Friday trading session ends - it includes the highlights of the current week.

A valid example of such a notification, to be exact a part of it, you will find in the picture below. Individual sections of the messages relate to the onscreen sections of the pattern table and they are narrowed to the most important data, according to what I have written above. The data are sorted by the absolute value of pattern potential in descending order.

Each section has maximum of:
  • 10 items in daily notifications,
  • 20 items in weekly notifications.

Individual parts of the email notifications also include the events detected in the main indices/futures and industry (sector) indices of the WSE. We have decided to divide the assets into two groups, as usually the indices/futures price movements are smaller (speaking of percentages) than those for stocks.
Not dividing them could result in skipping some of the potentially important patterns on the indices, because of their low potential compared to the patterns detected for the stocks. In this way, it is easier to observe the technical situation of the selected group of instruments, in the broad market, or in individual sectors.

Last, but not the least, I would remark that the notifications are sent only when at least one pattern event has been detected in the selected data scope and the selected time period, since the last notification.

Using the patterns list

This post describes the usage basics for the ATmatix patterns table. It is the most important part of the application. The list allows you to browse, search, filter and sort the patterns that have been automatically detected by our algorithms.


In the upper part of the web page, you will find the filtering buttons (tabs) that narrow the data view to patterns that are in a certain state – the tabs list is marked as A in the picture below:
  • All (without any filtering - all pattern states)
  • New/unconfirmed  – restricts the view to patterns which didn’t have breakouts yet; they may however be “close to upward breakout” or “close to downward breakout”
  • Near upward/downward breakouts – restricts the view to patterns close to breakout, but without the actual breakouts,
  • Upward/downward breakouts – narrows the view to patterns which had breakouts, but the target price after a breakout has not been yet achieved,
  • Completed – limits the view to patterns for which the target price was reached.

There is also the additional “Watchlist” button, which narrows the view to the assets that were added to the user’s favorites list. This button may be in enabled or disabled state and is visible to logged-in users only.
You can see the Watch List below the filtering tabs (marked as B in the picture). In order to add the stocks or indices to the list, you need to click (or tap) the list and type in at least 2 characters, to see the dropdown list with asset names that match the entered string.

After the entry is chosen from the list, it will be added to your Watch List. Attention: if a chosen stock has already been on the Watchlist and is chosen again, it will be removed from your Watch List.

To manually remove an asset from the Watch List, click the “x” button located next to the symbol in the list. You may also use backspace key to remove the last element from the list.
Clicking (or tapping) the symbol (but not the removal button of course) will narrow the content of the patterns table only to the selected asset.


Below the Watch List, there are buttons additionally limiting the pattern list only to stocks that belong to a certain group (marked as C in the picture above).
Currently, the available groups are:
  • All (no narrowing) – all the patterns are visible (albeit the state filtering still apply, of course),
  • WIG20, MWIG40, SWIG80 – only stocks listed in the selected index,
  • Main indices – only the patterns for the main WIG indices (WIG20, WIG20SHORT, WIG30, MWIG40, SWIG80, WIG etc. FW20 futures are also included in this group),
  • Sector indices – only the industry indices, such as: WIG-energy, WIG-oil&gas, etc.
To disable the group filtering, click the “all” button.


Below the Watch List, you will find the patterns table (marked as H in the screenshot).
The table is divided into pages, with max. 10 rows per page as the default. To change the number of entries per page, use the dropdown list (marked as D).
In the lower part of the list, there are navigation icons allowing you to move between pages (previous, next, page numbers) – marked as I in the picture.
Below the table, you can see the date of the last data update. The data is updated daily, after each WSE trading session ends.

The pattern list has the following columns:
  • Symbol/Ticker
  • Pattern type
  • Width (the number of sessions – or candlesticks – wthin the pattern, since the starting point of the pattern until its endpoint)
  • Potential – this is the range of the expected post-breakout price movement, calculated in accordance with the measure rule for a given pattern type, with the assumption of the anticipated (yet not 100% sure) breakout. The detailed information on target range measurement methods will be posted on the blog some time in the future. We have to mention that the value of the potential is being updated twice: right after the pattern detection and after a breakout (upward or downward) takes place.
  • Detection date – this is the day on which the pattern has been detected by ATmatix (also the date of the pattern’s end-point),
  • Near breakout – this is the last (newest) date of the price being close to the breakout level (upward or downward). Up or down arrow suggests the hypothetical breakout direction.
  • Breakout – the date of the actual breakout. The breakout can be the pattern’s confirmation or invalidation, depending on the type of the pattern, i.e. upward breakout is a confirmation for bottom patterns. The arrow suggests a breakout direction.
  • Target reached – the day the price has met the breakout target price range, previously set by ATmatix.  It means that the pattern was completed on that day.


Data are sorted by default by the value of two columns: the date of the last event (in descending order) and the pattern potential (also in descending order). Depending on the choice of the tab (new, near breakout, breakouts, etc.) the default sorting changes into:
  • Detection date (descending order), potential (descending) – for the “new/ unconfirmed” tab,
  • Near breakout date (descending order), potential (descending) – for the “near breakout” tabs,
  • The date of the breakout (descending order), potential (descending) – for the “breakout” tabs,
  • The date of reaching the target (descending order), potential (descending) – for the “completed” tab.
Any time you can sort the data by the desired column, by clicking/tapping the column’s header. If you want to sort the data using more than one column, you need to press and hold the SHIFT key, and then, click the chosen columns’ headers in a desired order, to set the sorting.

To restore the default sort order, use the button located on the right of the search box – marked as G in the picture.


In the upper side of the table, you can find the search input box – marked as E in the picture. The search engine allows you to find information according to the certain criteria. Type at least 2 characters – you don’t need to enter the whole name, ticker or symbol, but a fragment is just enough.

You may type:
  • A symbol, ticker or stock/index name. After typing at least 2 first characters the drop down list of the matching names opens.
  • You don’t have to choose the name from the list, as the filtering works immediately after typing a part of the name. If you decide to choose the name from the list, then the search results will be limited to that chosen asset.
  • Type of pattern – you can type a part of the pattern’s name (e.g. “wedge”, “bottom”, etc.)
  • The rest of the data visible in the table, such as pattern width, the potential, detection date, near breakout date, breakout date, and so on.
To use multiple search criteria, you need to separate them with space, e.g. “W20 bottom”, which will find all the bottom patterns for the instruments with names containing “W20”. For an exact match, you need to use the dot character (“.”), e.g..
  • ".WIG" (“.” in front of the name) narrows the results to the names starting with WIG)
  • "W20." (“.” following the name) restricts the table content to the names ending with W20
  • “.WIG.”(“.” In front of the name and following the name) narrows the results to the exact name (WIG only). 
To clear the search filter, you need to click the button marked as F in the picture (or delete the content of the “search” box).


On the left side of each row in the table, there is a button that expands the pattern details (you can also double click on the row, to expand it, or – in the mobile version of the page  – just tap it once).

Details include:
  • Name/type of the pattern
  • Upward/downward breakout statistics (displayed only for the patterns for which a breakout didn’t occur yet) –  this is visible for PREMIUM users only – the percentage of upward/downward breakouts that happened in the past. Because there can be both upward and downward breakout (i.e. there is an upward breakout, then the price reverses without meeting the target and the downward breakout occurs – so called pattern bust). In such cases statistics count the stronger of the two moves that occurred after breakouts. Another scenario is – no breakout at all (ATmatix tracks the chart pattern only for limited time after the breakout). That’s why these statistics don’t have to sum up to 100%.
  • Target range/statistical pattern effectiveness – price target range computed after the breakout (usually two values). One of the values is based on the measure rule for the given pattern type (typically, adding the height of the pattern to the breakout level), and the second is based on the statistics of the past pattern performance. Because the subject is really broad and in the nutshell this is the most important part of ATmatix, we are going to write a separate blog post on this topic).
    Given are also the absolute values (the target prices) and the expected percentage change in relation to the price of the breakout.
    Statistical effectiveness is the percentage of the historical breakouts reaching at least the given level (for upward breakouts, the price should reach the given level or higher, for downward breakouts it should reach the given level or lower). This information is available for PREMIUM users only and it allows you to evaluate the chances for meeting the expected price level. 
  • Volume trend – measures the volume change between the first and the last detected point of the pattern (it is computed for all the pattern points from the starting point till the day of its detection). This is the value calculated by applying the linear regression method and the trend is determined with a regression line slope. Usually, the theory states that in most cases the volume is decreasing during the pattern creation, but we’re going to describe our research on this matter in a separate blog post.
  • The breakout price – the price, being a base of a post-breakout target calculation (breakout happens when the price pierces this level). It is a point on the trendline (or horizontal level) that limits the pattern (top line for upward breakouts, bottom line for downward breakouts). 
  • Breakout volume – the comparison of turnover volume on the day of the breakout with the average volume of 30 pre-breakout sessions. It is assumed that the breakout volume should be clearly higher, which increases the chance for a stronger post-breakout movement. We are going to research this matter more closely in the future. Volume information is available to PREMIUM users only.
  • The throwback/pullback statistics and break even failure rates for a given pattern type.
In the details view, there is also a button available, which allows you to add or remove the selected stock from the Watch List.


Clicking the stock’s name in the “Ticker” column, or the name of the stock in the pattern details, opens the chart view. It is a modal window where you can find candlestick chart for the selected pattern and detailed information about the statistics, price targets and volume.

This view allows you to browse consecutive patterns from the patterns table, using the hidden arrows in the left and right side of the chart. Those links are invisible and to enable them, you have to move the mouse pointer to the edge of the chart.
The chart view

It is also possible to use the arrow keys on your keyboard, to navigate between the patterns.

What is also worth mentioning, is the chart view respects the filters and sorting applied to the patterns table, so after switching to the chart view, navigation to the next or previous chart matches the content and sort order of that table.

Chart view may be closed by clicking the X icon in the upper right corner of the modal window, clicking outside the chart window or pressing ESC on your keyboard.

Just a few words about the content of the chart itself.
The horizontal axis contains the dates of the stock market sessions. The scale corresponds to daily intervals. The date range includes only the period in which the pattern occurred along with certain margins.
Vertical axis is the price value on a linear scale. The values of the turnover volume are placed in the background of the chart (as light gray bars) and are scaled so that the maximum volume value in the time period shown is at the top of the vertical axis. The absolute values of the volume are not shown.

The visualization of the pattern includes:
  • Blue dotted lines connecting the detected pattern characteristic points (only for certain types of pattern),
  • Green and red lines indicating the trendlines within the pattern – piercing these levels by the price result in upward or downward breakout. Horizontal price levels are shown as dotted lines. The levels narrowing the linear patterns such as: triangle, inverted triangles, wedges, inverse wedges, channels, etc. are shown as solid lines,
  • Blue horizontal dotted lines denote target prices (if the breakout occurred).
The events occuring as part of the pattern, are marked with arrows (some examples are given below):

  • “near breakout”, when the price approaches the breakout level, is marked with a yellow arrow (after the breakout, this information is hidden, so as not to unnecessary complicate the chart)
  • The breakout is marked with a green/red color arrow (green for upward breakout and red for downward breakout)
  • Meeting the target price range (the pattern completion) is marked with blue color arrow. Upward pointing arrow indicates that the target price after a downward breakout was reached. Downward pointing arrow denotes the price target was reached after an upward breakout. 
The colors of the arrows in the chart match the colors of the arrows in the patterns table. Next to each arrow the information about the event price and the date of the event is shown. In case of the “near breakout” and the breakout event, the closing price is displayed. In case of target achieved event, the daily low (L) or high (H) price is shown – depending on the breakout direction.
