Log of Changes and Improvements to Sierra Chart

This list contains major items of development, items which are notable, and changes and additions which users need to be informed about.

This is not a comprehensive changes and additions log. It only represents less than 25% of the actual development performed every day. There are not version notes for each version. The main Sierra Chart documentation is updated as needed relating to the changes and additions.

In addition to the below listed items for each version, there are also various low-level improvements, issues resolved, and small additions that a release has which are not listed.

  • 2351 Release Date: 2022-01-31

    • Support for new NASDAQ TotalView data feed.
    • For CQG users, historical tick by tick data (including historical bid volume and ask volume) support has been removed for the CME Group and EUREX exchanges when using data direct from CQG. This only applies when you are using real-time and historical data direct from CQG, and not from the Denali Exchange Data Feed provided by Sierra Chart. This does not affect Denali Exchange Data Feed users.

      If you require historical tick by tick data, you must use the Denali Exchange Data Feed when using CQG. Understand, when CQG support was added by Sierra Chart there was not the intention to add market data support. We do not want to support CQG data. It creates a poor impression for Sierra Chart for numerous reasons and we do not want to answer any technical questions about CQG data. We are our own data provider. CQG historical data is hugely inferior to what Sierra Chart provides. Sierra Chart provides 10+ years of historical tick by tick and daily data delivered fast and efficiently and processed on a background thread. Whereas with CQG you get data for current contracts only.

      We are phasing it out to the extent possible. If you require proper data for Sierra Chart, you must use the Denali Exchange Data Feed. You only need to pay for the exchange fees once. When you pay them through the Denali Exchange Data Feed, you then cancel them through your broker. You will also cancel historical market data access from your broker for CQG.

      One of the reasons, that historical tick by tick data was always limited by Sierra Chart when accessing it from CQG, is that it is processed on the primary thread of Sierra Chart, unlike data from Sierra Chart provided historical data services which is a background thread, and it is provided in time reversed order from CQG. Downloading of this historical chart data causes the user interface of Sierra Chart to freeze and there is excessive memory use. It is also slow to download from CQG.

      And for the lowest cost and highest quality and most advanced, futures order routing you need to use the Teton Order Routing Service instead of CQG. Depending upon the amount of trading you do, you can save substantially (.00 USD (Teton) per contract versus .10 USD (CQG) per contract), and have superior order routing as compared to CQG. You also eliminate the monthly connection fee to CQG that CQG charges.

      Until you use the Denali Exchange Data Feed, you can go back to a prior version of Sierra Chart. You will need to re-download the historical data to obtain tick by tick data for up to 5 days.

      Effective by April 2022, for new users and for usage time renewals, Service Package 10, 11, or 12 will be required to use CQG.
  • 2348 Release Date: 2022-01-20

    • Resolved issues with new implementation of Global Settings >> General Settings window.
    • Chart/Trade DOM performance improvements. These will be especially noticeable when there are more than 10 levels of market depth levels displayed. The more levels, the greater performance improvement. Further performance improvements will be made in the next two weeks.
    • Resolved a problem where, the Quantity value in the Trade >> Trade Positions Window may not synchronize to the Service Position Quantity field also in this window. This is not a common issue. It is important to update as soon as possible.
  • 2346 Release Date: 2022-01-16

    • Changes to how back adjustments are done for continuous futures contract charts. The prior day settlement prices are now used rather than the current day open prices.
    • Added new Input for Numbers Bars study called Color Non-Dominant Ask/Bid Text Same as Opposing Side. When set to Yes this Input will force the coloring of the non-dominant Ask/Bid at the same price level that would typically be drawn in the Default Text Color, to be drawn using the same color as the opposing sides color. This does not color diagonally, even for diagonal comparisons.
  • 2344 Release Date: 2022-01-12

    • Resolved a problem affecting version 2342 and 2343, where when opening a file for overwrite mode, the file may not have been truncated and may have contained at the end of the file some left over data from the prior state of the file. This left over data at most would cause an error when the file is opened and successfully read. Another condition would be a file may not have been cleared when it should have been. This could for example cause the orders list to show the prior state of orders. This primarily affected, the orders list file, positions list file, and trade activity files. These versions have been locked out.
  • 2342 Release Date: 2022-01-08

    • Released in a prior version: Updates to the Market Depth Historical Graph including bug fixes for Automatic Combine Increment in Ticks and support for determining Maximum/Minimum depth from Trading Day or Per Session
    • Released new chat functionality which can be opened through File >> Open Chat Window.
  • 2337 Release Date: 2021-12-20

    • Corrected an issue which at least affected EUREX EOBI market data when using Combine Trades into Original Summary Trade and back adjusted Continuous Futures Contract charts, where historical bars may have out of range values due to the back adjustment being applied twice.
    • Corrected an issue from a recent release where .5 second of data was being filtered out from the chart bar which would end at the Session End Time.
  • 2331 Release Date: 2021-11-26

    • Added support for third Internet connection for Teton Order Routing service.
    • Enhancements to Duplicate Chart interface.
    • Added new UseSingleClickToEditItemInSettingsWindow setting to General Settings.
    • Resolved issue with Combine Trades into Original Summary Trade when used with EUREX data from the Denali Exchange Data Feed where when the exchange did not provide an indication of the end of the block of trades that belong to a summary trade, there could be trades which were filtered out from the chart bars.
  • 2327 Release Date: 2021-11-10

    • Resolved issue from a recent release where the Step 2 for Move to Breakeven Stop did not function.
    • Implemented solution to issue where when connecting to the Denali Exchange Data Feed more than once from the same computer, the connection sometimes would be denied due to different devices being detected.
    • Corrected issue with real time and historical data for Binance not being requested. This issue arose in a recent release.
    • Previously Released: With the Trade Account Settings window, when there are uncommitted changes for the Symbol/Products Limits or Symbol Commissions tab, and an Update operation is performed, those uncommitted changes are no longer removed. They will be maintained and can be committed subsequently.
    • Import and Export functionality has been added to the Trade Account Settings window for the Symbol/Products Limits or Symbol Commissions tabs.
  • 2323 Release Date: 2021-10-25

    • Resolved an issue from a recent release affecting subscribing to market data and downloading historical data for spread symbols for the Sierra Chart Order Routing service.
    • Improvements with switching to backup connection when using the Sierra Chart Direct Order Routing service.
    • Support for market data from the FairX exchange.
  • 2310 Release Date: 2021-09-08

    • Corrected an issue from recent release where the order of study Inputs for the RSI studies was mistakenly reordered. If you have saved your Chartbook since updating to a version where these study Inputs were reordered, then after updating to version 2310 or higher, it is necessary to access your Backup Chartbooks to have the original Input settings restored. Or you can just modify the study Inputs manually to what you previously had set.
    • Support for the old Rithmic connection has been removed. Only the new service (Rithmic Direct - DTC) can be used which will be automatically selected if the old Rithmic connection was previously selected. Rithmic has limited historical data and for complete historical data, it is necessary to use the Denali Exchange Data Feed when using Rithmic. Historical data for the old Rithmic connection was always provided by the Sierra Chart Historical Data Service which is the same historical data as the Denali Exchange Data Feed, other than the most recent 10 minutes of data which came from Rithmic.

      Therefore, the historical data that Rithmic users have been used to when using Sierra Chart has always been provided by Sierra Chart other than the most recent 10 minutes. Gradually across all supported Trading services, historical data now either comes completely from the external service or completely from Sierra Chart provided data feeds for complete consistency and simplification with data access. This has now been implemented with Rithmic as well.

      When updating to this version or higher, it is necessary to translate symbols to the new Rithmic symbol format which use a dot as compared to a - for the delimiter between the symbol and the exchange. To do this, refer to Translate Symbols to Current Service.
  • 2308 Release Date: 2021-09-08

    • Support for direct CME order routing. The Trading Service is listed as SC CME Futures Order Routing in Global Settings >>Data/Trade Service Settings. We expect this service to become available for users to use, towards the end of September or the beginning of October 2021. This service provides high-quality, very low latency, direct order routing to the CME with advanced risk management.
    • Corrected issue with adjusting secondary anchor point on the Pitchfork drawing tool.
    • Corrected an issue with Attached Orders Scale Out that occurs under certain circumstances where an additional Stop order was having scale out applied when it should not be.
    • Corrected an issue, with ACSIL n_ACSIL::s_LineUntilFutureIntersection lines that use UseLineValue2 where the lines were not always stopping at future intersection bars.
    • Resolved an issue from a recent release causing order fills for the Trading Evaluator service to have an incorrect timestamp. This would cause them to effectively not be seen in the Trade Activity Log.
  • 2296 Release Date: 2021-08-12

    • Resolved a problem that a small number of users have had, related to modifying orders within the chart or entering orders, which could result in a stack corruption and an abnormal shutdown of Sierra Chart. It is believed that this issue, was a problem at the compiler level.
    • Added new Angled Ellipse drawing tool.
    • The Start Time for the internal Trades list of a chart, when a chart is maintaining a trades list, now has a separate setting. This is Chart >> Chart Settings >> Trading >> Start Time for Trades List.
  • 2293 Release Date: 2021-07-31

    • Effective with version 2288, custom study functions that use the sc.SmoothedMovingAverage function need to be recompiled due to changes with the parameters of this function.
    • Corrected issue from a recent release where the price display formatting in the Trade Orders List may not be correct in all rows. This was related to an optimization that was done and an unexpected side effect.
  • 2280 Release Date: 2021-06-26

    • The median line beginning point of a Pitchfork drawing can now be changed by adjusting the two immediate parallel lines to the median line. This is supported for the standard Pitchfork drawing but not yet properly supported for Schiff and Modified Schiff pitchfork drawings. Support for these types of Pitchfork drawings will be implemented as soon as possible.
    • We have had a few reports, upon opening a Chartbook, where the symbol of the charts were changed to what appears to be a corrupt symbol. We have determined the cause of this, and resolved it. It is *not* due to a direct programming error or any corrupt values within Sierra Chart or the Symbol Settings. The reason for this is because there has been a case where when translating symbols in a Chartbook when the Chartbook is being opened, an event triggered apparently on a window creation of a chart, related to the updating of symbol settings which caused the translation database to be cleared causing corrupt values to be used previously when a reference was being held to the STL container object containing the database. This caused invalid symbols to be set within charts during the translation. This was a completely unexpected behavior at the operating system level. A message event on the same thread should never have been occurring, during execution of an unrelated event on the same thread.

      Anyway, this problem is now resolved and it is very important that all users update to this release or higher as soon as possible to avoid the potential of this issue. We still need to look at the range of versions affected. It would be approximately versions in the last 3 to 4 months. In our experience, it is a rare issue but it could potentially happen.
    • Various other development related to risk management, and managing Trade Account settings for the trade simulation service and live order routing.
    • Resolved a problem, where there would be an unnecessary connection to a market by order server, for option symbols for the Denali Exchange Data Feed. Options do not support a separate connection for market by order data and there would be a continuous reconnection to an invalid server port. Options also do not support this type of data either.
  • 2273 Release Date: 2021-06-12

  • 2268 Release Date: 2021-05-31

    • Advanced Custom Study Control Bar buttons can now be independently selected and are independently tracked. There is also an internal variable which indicates the button number of the most recently activated Advanced Custom Study Control Bar button. It is this button number which is indicated to custom studies that are receiving Pointer input. If that same button is changed to an off state, then this variable is cleared. Whenever an Advanced Custom Study Control Bar button is pressed, whether changing the state on or off, all chart studies are set to receive this type of input are called indicating the selected button number, and whether the state is on or off.
    • When a custom study DLL file is unloaded, there is now a call to study functions in that DLL, with the sc.LastCallToFunction ACSIL variable set to true.
    • Support for market by order data (MBO) on separate connection. This data is now delivered on a separate connection in order to not impact the latency of standard trade and market depth data. Market by Order data is provided with the Denali Exchange Data Feed and the Delayed Exchange Data Feed.
    • Resolved various small issues, related to market by order data on a separate connection.
    • Support for accessing Denali Exchange Data Feed from the NY4 server. This applies to the upcoming CBOE Futures data, and NASDAQ stock data. Both of these data feeds provide full market depth. CBOE futures data will support market by order data.
  • 2256 Release Date: 2021-05-09

    • Corrected a problem with the CQG Trading service where when using the Denali Exchange Data Feed, there was an unnecessary request for historical Minute data from the Denali Exchange Data Feed, followed by the standard historical data request. This would not occur under all conditions. This issue is now resolved. This problem arose, when Sierra Chart switched to using CQG historical data rather than the subsidized historical data system that we developed for CQG.

      This is considered a critical update. Any user using CQG will need to update.
  • 2255 Release Date: 2021-05-08

    • Added new fields to Trade Positions Window and Trade Accounts Monitor (Account Balances) window used by the Sierra Chart Simulated Trading Service and the upcoming Sierra Chart Direct Order Routing Service.
    • Implemented full support for creating and managing trade accounts for the Sierra Chart Simulated Trading Service and the upcoming Sierra Chart Direct Order Routing Service, directly within Sierra Chart. This is accessed through Trade >> Trade Accounts Monitor >> Manage. In the case of the Direct Order Routing Service, creating and managing accounts would only be done by a clearing firm.
    • This version has support for all the latest enhancements with the Simulated Futures Trading Service. When updating to this version you will automatically use the new version of this service if you have been using either the delayed or live version of this service. You will need to re-create your trading account on this service if you have an existing one. For instructions, refer to Setup Instructions.
  • 2253 Release Date: 2021-04-27

    • Full implementation of new interface for creating and managing trade accounts for the simulated futures trading service and the upcoming Sierra Chart direct order routing service.
    • Corrected a problem when using the Add Additional Symbol study on a Continuous Futures Contract chart, where the first date loaded would be the same date as the most recent futures contract date loaded in the chart. This is now resolved and the first date for the Add Additional Symbol study will be the same as the First Date in the chart assuming there is data available back that far for the symbol set in the Add Additional Symbol study.
    • Various Quote Board enhancements, related to inserting and removing symbols for multiple rows.
  • 2247 Release Date: 2021-04-07

    • Corrected issue from recent release affecting downloading of historical data from Interactive Brokers where for symbols where there are no Symbol Settings, the historical data download was being skipped.
    • Removed s_MarketDepthUpdateLevel_Int DTC message support.
    • New Draw Mode in Large Volume Trade Indicator for Based on Total Ask Bid Volume Above Threshold - Diagonal Difference.
    • The settings: "Support Downloading Historical Market Depth Data" and "Max Historical Market Depth Days to Download" are now both in Global Settings >> Sierra Chart Server Settings.
  • 2230 Release Date: 2021-02-13

    • Support for the new EUREX data feed for real time and delayed and historical data. It is necessary to be running this version or higher to access any EUREX data. This was not expected to be the case unless you required real-time EUREX data but we realize now, that all users requiring EUREX data will need to update to this version or higher. We do apologize for this requirement.

      It is important to not be too far behind with Sierra Chart updates. You should generally be up-to-date within the last three months.
    • Resolved a potential issue related to changing the quantity of an order or canceling an order on the chart which could potentially cause an exception.
    • New studies added: One Time Framing, Covariance, and Premier Stochastic Oscillator.
  • 2226 Release Date: 2021-02-01

    • Added functionality to the Large Volume Trade Indicator to support the Total Bid/Ask Volume. When selected, the larger Total Bid or Total Ask volume at that price is displayed.
    • New studies added: - Moving Average - Variable Index Dynamic, RAVI, Turbo MACD
    • New Subgraphs for Numbers Bars Calculated Values 2: Time Since Price Touched Bar High and Time Since Price Touched Bar Low.
    • New Draw Mode options in Large Volume Trade Indicator. Based on Entire Bar Total Volume Above Threshold and Based on Entire Bar Bid/Ask Volume Above Threshold.
    • Corrected a minor inefficiency issue in charts when market depth data is subscribed. Additionally in the case when the chart symbol uses a Real-time Price Multiplier other than 1, if the chart uses market depth data, it would always update under certain conditions even when there was no market activity.
    • Advanced Custom study DLL loading management. For more information, refer to this Support Board thread.
  • 2219 Release Date: 2021-01-12

    • Implemented new Global Settings >> Data/Trade Service Settings window using the new settings window format.
    • Added new Global Settings >> Data/Trade Service Settings >> Common Settings >> Maximum Historical Market Depth Days to Download setting.
    • Implemented Advanced Custom Studies DLL Loading Management.
    • Corrected a problem with the CQG trading service, where when getting the option symbols for a particular symbol from CQG, or using a CQG symbol as a Trade only symbol, and that particular symbol was not used for obtaining a quote or a chart during the connection, when a chart is later opened for that symbol or it is used on a quote board, and the market data is requested from CQG at that time, the correct_price_scale variable had not been processed in the symbol resolution report.

      Therefore, leading to incorrect prices when processing market data. This is an unusual scenario and the underlying reason for this is a not well-designed API from CQG and a design that we fundamentally disagree with for various reasons including the fact that it greatly increases code complexity with the mapping of symbols to server assigned and connection specific IDs which CQG uses. For example, even submitting an order requires an integer identifier rather the actual symbol. This specific design is not used by any other supported Trading service. This issue arose when we added support with the CQG Web API to use a Trade Only symbol which originally was unsupported due to this unusual design from CQG.

      There are also other verified causes of incorrect data from CQG which are unrelated to this and are a CQG server issue.
  • 2214 Release Date: 2020-12-29

    • New ACSIL functions added:
      sc.GetBidMarketLimitOrdersForPrice (for accessing the market by order data)
      sc.GetAskMarketLimitOrdersForPrice (for accessing the market by order data)
    • Some changes have been made in ACSIL regarding modification of Chart Drawings which use the s_UseTool::RetracementLevels[] structure array member.

      The following structure members: s_UseTool::Color, s_UseTool::LineWidth, s_UseTool::LineStyle now will only modify what are regarded as the special levels of these types of Chart Drawings. These are levels that you can see in the Chart Drawing Properties/Configuration which cannot be removed. For example, the main sloping line of the Price Retracement drawing would be considered a special level.

      It is now supported to add additional levels just by setting the value for those levels within the s_UseTool::RetracementLevels[] array.

      To change any of the appearance properties of the visible levels, not the special levels, then this can only be done through the following structure array members: s_UseTool::LevelColor[], s_UseTool::LevelStyle[], s_UseTool::LevelWidth[].
  • 2211 Release Date: 2020-12-19

    • New ACSIL member to access the same data as the Large Volume Trade Indicator study: sc.p_VolumeLevelAtPriceForBars. This is a pointer to this class: c_VolumeLevelAtPriceContainer. This class is derived from c_VAPContainerBase and uses the s_VolumeLevelAtPrice data structure. Therefore, it functions the same as sc.VolumeAtPriceForBars except that the structure is of type s_VolumeLevelAtPrice.
    • Support for Market by Order of from the CME. This only works with the Denali Exchange Data Feed and the Delayed Exchange Data Feed. This is enabled through Global Settings >> Sierra Chart Server Settings >> Subscribe Market by Order Data when Market Depth Subscribe.

      The position in queue for the orders may not be correct as it is based upon the exchange order ID whereby a lower order ID means an order will be considered to be filling earlier than orders with a higher order ID. This may not actually be correct because as an order is modified, the CME order ID remains the same. If we have this wrong, additional work is required for us to utilize the timestamp of an order update from the exchange to determine its position in queue.
    • Ability to hide Trading Account list Box on Trade Window. Accessible through the Trade Window Settings sub menu.
    • Added option on Scale Window for Use in Left Side Scale. The first found study that has this enabled will be used to set the scaling for the Left Side Scale (if it is enabled). This setting is Off by default, therefore if you had a study that was setting the Left Side Scale, you will need to enable this option for that study to continue to have it set that scaling.
    • Universal support for wide/16-bit/Unicode characters. Now all character sets in the world can be used throughout Sierra Chart universally. The menus can be customized. Soon there will be support for customizing the text of control bar buttons into another language and also for the settings names within the new Settings Windows which are replacing the older dialogs in Sierra Chart. This will bring about universal support for any language within Sierra Chart. Also it is now supported to use any character set when setting text on Chart Drawings.
  • 2204 Release Date: 2020-11-27

    • Resolved a problem from version 2199, where historical Intraday data for exchange traded symbols other than the CME Group was not being downloaded when using SC Data-All Services and you did not have one of the Sierra Chart Exchange Data Feeds active on your Sierra Chart account. This is now resolved.
    • Resolved problem with the initial loading of market depth data in a chart, where there was excessive amount of records processing which would cause freezing of Sierra Chart. If you are using the Market Depth Historical Graph study, it is essential to update to this version or higher. Our analysis of the problem is that this has been a long-standing issue. If you have experienced delays or freezing when opening a Chartbook, and you are using the Market Depth Historical Graph, then most likely it is due to this reason.
    • New Subgraphs available in Numbers Bars Calculated Values 2: Volume Above Volume POC and Volume Below Volume POC.
    • TPO Value Area can be colored differently for Day and Evening Sessions when TPO Block/Letter Color is set to Separate Colors for Day and Evening Sessions.
    • The High Compression option is now available again in Global Settings >> Sierra Chart Server Settings. This works with all Sierra Chart provided data feeds and provides a higher level of data compression.
    • Added two new studies: Gann Trend Oscillator and Gann Swing Oscillator.
  • 2196 Release Date: 2020-11-17

    • Resolved an issue with the Daily OHLC study preventing the lines from being calculated when using an evening session in the Chart Settings which starts before 12 PM.
    • Resolved an issue with the High/Low for Time Period-Extended study with the Line Stop Time Input not being followed when it is near the end of the day in some cases.
    • Resolved problem where replay does not continue at the transition from one futures contract month to the next, when the chart is using the Continuous Futures Contract option.
    • Continued development of support for downloading of historical market depth data. This is expected to be released soon.
    • The SCDateTime and SCDateTimeMS Date-Time classes used within ACSIL and Sierra Chart are now exactly the same. SCDateTime now functions exactly like SCDateTimeMS where when comparisons are done, they are done to the microsecond rather than to the second. And there is no longer any internal rounding to the nearest second in SCDateTime for functions which would previously do this like SCDateTime::GetTime.
  • 2195 Release Date: 2020-11-11

    • New setting in Customize Chart/Trade DOM Columns called Use Size Suffix. When enabled for a column, the size data for that column will be displayed using the Large Integer with Suffix format.
    • New Input on Market Depth Historical Graph named Automatic Combine Increment Adjustment Value which, when set to a value greater than 5, will allow the Market Depth Historical Graph to automatically combine/disjoin increments as the chart scale is changed.
    • The return type for the following ACSIL functions has been changed from a double type to SCDateTimeMS. Previously this was not done when the new integer based SCDateTime/SCDateTimeMS were released since using these types as a return value would lead to an invalid return value when using other compilers other than Visual C++. We have tested again with the compiler used for the Sierra Chart Remote Build functionality and do not observe any problem with this. So we have now changed the return type to SCDateTimeMS. It was necessary to make this change because there is a small degree of floating-point error when using a double type that would lead to a time value being off by a microsecond which can cause a problem when that is not expected. Therefore, any ACSIL study which uses these functions needs to be recompiled for version 2195 or higher. If the study is not recompiled, then the functions will do nothing and add an error message to the Sierra Chart Message Log.:

      sc.GetStartDateTimeForTradingDate, sc.GetTradingDayStartDateTimeOfBar, sc.ConvertDateTimeToChartTimeZone, sc.DateStringToSCDateTime, sc.AdjustDateTimeToGMT, sc.TimePeriodSpan, sc.TimeStringToSCDateTime, sc.DateStringDDMMYYYYToSCDateTime, sc.CalculateTimeSpanAcrossChartBars, sc.GetEndingDateTimeForBarIndex, sc.GetEndingDateTimeForBarIndexFromChart, sc.ConvertDateTimeFromChartTimeZone, sc.ConvertDateTimeFromChartTimeZone.
    • Continued development related to downloading historical market depth data.
  • 2191 Release Date: 2020-10-31

    • Added new fields to the Account Statistics tab of the Trade Activity Log including Open Profit/Loss (updates in real time) and Net Profit/Loss.
    • Updated Global Settings >> General Trade Settings window to the new high-performance settings window format.
    • Added to the Global Settings >> General Trade Settings window the Trade Order Alert Trade Accounts Filter which can contain a list of trade accounts to generate trading alerts for. Trade alerts will not be generated for unlisted accounts. If this setting is blank, trading alerts are generated for all trading accounts.
    • Resolved stability issue related to file compression described in this Support Board thread.
  • 2187 Release Date: 2020-10-27

    • Corrected a problem from a release about middle of July 2020, where file compression was not automatically being enabled for Intraday data files and market depth data files. The reason this occurred is that the file handle being used for compression did not have write access to the file. The compression that Sierra Chart uses is NTFS compression provided by the operating system. If compression was enabled on the Data Files Folder Sierra Chart is using, then you would have had compression anyway. We have also implemented asynchronous compression, so when compression is enabled on a large file, the compression occurs in the background.

      During the time that the operating system is compressing an Intraday data file or market depth data file, there will be slower performance with reading these files in Sierra Chart. Once the operating system is finished compressing these files, which should just take no more than a few minutes, usually, then the performance will return to normal and actually be improved. The initial compression is just a one time operation.
    • Various new features added to the TPO Profile Chart study. One feature allows up to five independent sessions/TPO profiles per trading day. The TPO Profile Chart study Inputs for this are: Number of Custom Intraday Sessions, Custom Intraday Session # Begin Time, Custom Intraday Session 1 End Time.
