Log of Changes and Improvements to Sierra Chart
This list contains major items of development, and changes and additions which users need to be informed about.
This is not a comprehensive changes and additions log. And it should never be relied upon for such. It only represents a very small percentage of the actual development being performed every day. The vast majority of development is not documented here. Or receives, one small comment after it is all complete. There are not version notes for each version. The main Sierra Chart documentation is updated as needed relating to the changes and additions.
The maintenance of this page has mostly been abandoned by Sierra Chart development for many years due to the difficulty of maintaining it and because users can be incorrectly misled by or misinterpret notes that are made here. This does not change, the development of Sierra Chart which is very active every day and new releases are made nearly weekly or several times a week. The Sierra Chart project is still very active, with extensive development and it remains a very high quality software in the world. The engineering is at the very top of the world.
-
1693 Release Date: 2018-01-23
- Add Additional Symbol study improvements.
- Horizontal Ray Tool now has option to be extended until future intersection with price bars.
- Specify an ACSIL sent order to be held on the client-side and later sent through the Trade Orders window tab. Variable: s_SCNewOrder::SubmitAsHeldOrder.
- Ability to start through the Trade menu a bar based back test for all symbols in the Associated Watch List for a chart.
- New study Subgraph Draw Style: "Line at Last Bar to Left Side".
- More graceful reconnect handling when using the CQG FIX Trading service. Although this has not yet been tested but we do not expect any issues.
- In the Analysis >> Studies >> Studies to Graph list, the calculation order index, if known is displayed after each study in the list. This lets you understand the order in which studies are calculated. This can be different than the order in which the studies are listed in the Studies to Graph list.
- Support for the Oanda Forex/CFD broker provided by an external service. Connectivity to Oanda is provided by an outside service and may not be available at this time.
-
1684 Release Date: 2018-01-08
- Additional work on the Add Additional Symbol study. Various improvements have been made and corrected a problem with this study which would cause Sierra Chart to freeze after a period of time and would require a forced shutdown to recover from this condition. Internally what was happening was a deadlock condition related to mishandling of synchronization locks related to background writing of Intraday file data. If using this study, it is essential to use this version or higher.
- Fixed an issue with Renko bars related to the filling of gaps at the first trade of the day. New Renko New Bar Modes added.
- When connected to an external trading service which does not use the DTC protocol, when a bracket order is received from a sub instance, the child orders of the bracket order sent out to the external trading service, if supported, now have the proper quantity instead of 0.
- Associated Watch List new features: New menu command to set charts in Chartbook to symbols in watch list. When setting charts to the symbols of the watch list, there is now a prompt to automatically open additional charts as needed.
- Corrected problem where sometimes chart tabs would not move when dragging them.
- Added support for dragging Chartbook tabs to be able to reorder them.
- Additional improvements to the Study Summary window feature.
1678 Release Date: 2017-12-29
- The data structure used by the new ACSIL function sc.GetBarPeriodParameters() which was released in 1677 has been changed. It is essential to recompile when using this version or higher to avoid a stack corruption, if you are using this function. A corresponding sc.SetBarPeriodParameters() is being added to the next release. Between these two functions, there is now in an easy to use unified way to get the bar period parameters and set the bar period parameters rather than the various other variables like sc.SecondsPerBar.
- Corrected a problem which arose in the prior release with the Add Additional Symbol study where chart bars for that study during a replay or real-time updating, were incomplete or did not contain any data. The Add Additional Symbol study now supports all of the replay back testing modes. Although at this time Bar Based Back testing is not supported with the Add Additional Symbol study. It will be in the next release.
1677 Release Date: 2017-12-27
- Added ACSIL member sc.IsChartbookBeingSaved to indicate when Chartbook is being saved. Study functions are now called when Chartbook is being saved so a study can perform whatever actions it needs to.
- Added new ACSIL members: ConstantRangeScaleModeTicksFromCenterOrEdge, GetBarPeriodParameters(n_ACSIL::s_BarPeriod& r_BarPeriod).
- Completed development of the Add Additional Symbol study.
- Additional enhancements to the Study Summary window.
- Improved the management of Attached Order offsets for bracket orders that originate through the DTC Protocol Server.
- Improved Spreadsheet saving and loading performance. This will be similar to as it was before the changes to reduce memory use when saving and loading Spreadsheets.
- Corrected some issues with exporting of study data when using Edit >> Export Bar and Study Data to Text File or when using the Write Bar and Study Data to File study.
1674 Release Date: 2017-12-22
- New Numbers Bars Background Coloring Method and Text Coloring Method named Based On Separate Diagonal AskVol BidVol Percentage. When using this new coloring along with a display that shows both the Bid and Ask sides, the coloring will always be present for both the Bid and Ask sides regardless of which side is dominant. When displaying a single item, the coloring is chosen based on the dominant side. The comparison is done using a Diagonal Percentage of Ask/Bid or Bid/Ask Volume.
- The move to breakeven price for Stop Attached Orders now adjusts for Scaling In to use a weighted average.
- Study Summary window now supports all of the available Quote Board fields.
- Corrected a problem with the loading of chart data which occurred in a recent release that some users were experiencing where the load would not either complete, or it would occur on the primary thread causing Sierra Chart to freeze during the loading process. In most cases there was not a problem but it could occur under some conditions.
- Nearly completed the development of the new Add Additional Symbol study which loads chart data for an additional symbol into the chart.
- Various other low-level development.
1670 Release Date: 2017-12-15
- When opening and saving spreadsheet files, this is done using a new streaming format where a minimum amount of memory is used.
- In version 1662, the new underlying file format for spreadsheets was released. Any spreadsheet saved with this version or higher cannot be used by an older Sierra Chart version. However, there are backups of spreadsheets available.
- With the LMAX trading service, symbols from the SC Exchange Data Feed can now be used. These will be added on request as needed.
1663 Release Date: 2017-12-08

- Study Summary now supports displaying studies from multiple Chartbooks. This can be enabled through the Settings menu on the Study Summary window.
- Low-level improvements with the Global Profit/Loss Management feature. For example, the loss management could have potentially triggered more than once per day.
1659 Release Date: 2017-12-08
- Corrected an issue from 1658 that prevented the reading of Spreadsheet files. If it is necessary to access a backup Spreadsheet file, refer to Accessing a Backup Spreadsheet File.
1658 Release Date: 2017-12-05
- Corrected problem that has existed for at least several months where when a chart is reloaded, an operating system window handle was created but not released. Over an extended time this potentially could cause an issue where window creation fails.
- Improvements with the chart bar gap fill options. Additional low-level Renko bar improvements.
- Additional work on the Study Summary window.
1656 Release Date: 2017-12-01
- Added Estimated Position in Queue tracking for non-simulated Limit orders.

1651 Release Date: 2017-11-25
- Completed development of the new Study Summary window opened through File >> Open Study Summary window .
- When using a sub instance through File >> New Instance, the necessary data to recombine trades into the original summary trade is now passed through.

1646 Release Date: 2017-11-19
- New ACSIL members: CalculateAngle(), NumberOfForwardColumns, AllocateAndNameRenkoChartBarArrays, OpenChartbook(), IsDateTimeInEveningSession()
- Added new Study Summary window for Chartbook. This is opened through File >> Open Study Summary Window. This feature is still under development.
- Changes to Renko bars. The Renko New Bar Mode option for a new reversal bar to reference the prior close always, has been reimplemented to be "New Reversal Bar When Reversal Amount Met Plus 1 Tick". This corrects a problem with the previous setting, where it did not function properly in most cases and produced incorrect Renko bar charts. It functioned properly only in one isolated test case that it was tested against. The current implementation is a more proper and logical implementation according to the objectives we understand from those who need this and we expect should match Universal Renko bars in another popular implementation used by another program.
- Additional options to control the formation of Renko bars has been added to Chart >> Chart Settings >> Intraday Chart Bar Period. There are a total of nine options giving you a greater degree of control.
- Universal Renko Bars have been renamed to Flex Renko Inverse Setting Bars since they use inverse settings compared to Flex Renko bars. Also, Flex Renko Inverse Setting Bars no longer require a reversal to be one tick more than the Reversal Bar Trigger amount. The reversal amount is simply the amount of Reversal Bar Trigger.
1641 Release Date: 2017-11-09
- The parameters and implementation of the ACSIL functions sc.RelayNewSymbol and sc.RelayTradeUpdate have changed. If your custom study is using these functions, it must be updated to the current function specifications and recompiled. Otherwise, there will be instability and malfunctions. The ACSIL function sc.CreateRelayServer has been removed. Refer to the ACSIL Functions page for details.
- Changes to ACSIL sc.GetStudyPeakValleyLine function. Any custom study using this function must be recompiled. Refer to the ACSIL Functions page for details.
- Ability to set Subgraph line Name and Value Labels to a different color than the subgraph itself. The new settings are in the Study Settings window.
- Additional options to control the formation of Renko bars has been added to Chart >> Chart Settings >> Intraday Chart Bar Period. There are a total of six options giving you full control. This is especially useful when using the Numbers Bars study on a Renko bar chart.
- New option on Trade Window menu (Menu/M) to cancel orders when the Trade Position Quantity goes from nonzero back to zero. The command is Menu/M >> Orders >> Cancel Orders on Flat Position.
- Added the ability for ACSIL studies to create custom chart bars very efficiently. Refer to the /ACS_Source/ACSILCustomChartBars_Example.cpp file for an example.
- Upcoming: Added Ask Bid Difference optional field to the Chart Header.
- A change to the Numbers Bars study when using the Text Coloring Method Based on Diagonal Dominant AskVol BidVol Percentage. Previously, it was not coloring the text sides based on whether they were dominant, it was just coloring both sides at all times, except when there was a comparison to 0. This was inconsistent with both the name of this text coloring method and the other Diagonal Dominant coloring options. The change now makes this consistent with the other options, where now each side will only be colored if it is diagonally dominant. Refer to the updated Based on Diagonal Dominant AskVol BidVol Percentage documentation.
1635 Release Date: 2017-11-03
- Much improved order error handling with Interactive Brokers Trader Workstation based on the TWS error codes.
- Corrected problem from recent release, where not all studies available were listed in Analysis >> Studies.
- Corrected problem from a recent release, where the reversal offset was not being applied for Flex Renko and Universal Renko bars.
- For Chart and Study Simple Alerts, when using Renko bars the base graph identifier C now makes reference to the Renko Close value and the identifier O now makes reference to the Renko Open value.
- Added studies: Combination Symbol Chart and Price, Open Interest, Volume .
- Implemented the following Alert option for the Chart Settings and Study Settings Alerts tab: Log Evaluated Formula at Each Evaluation. This is to be used for troubleshooting purposes only. The evaluated formula is displayed in the Window >> Alerts Manager >> Alerts Log.
- Corrected a problem with the ACSIL s_UseTool structure occurring from a recent release related the addition of a new member which has apparently caused an unexpected structure misalignment.
1632 Release Date: 2017-10-31
- Added new Intraday Chart Bar Period >> Gap Fill option to fill gaps between chart bars other than at the start of the trading day. Corrected a small issue with filling gaps in Intraday charts.
- Minor change to new Renko implementation to ensure Renko brick/boxes, are adjacent to each other. This may also require using one of the Intraday Chart Bar Period >> Gap Fill options.
- Added new ACSIL function to read Intraday records contained within a chart bar: sc.ReadIntradayFileRecordForBarIndexAndSubIndex.
1630 Release Date: 2017-10-28
- Additional improvements and small issues resolved with Renko Bars.
- Added new ACSIL function to read from the Intraday data file for the symbol of the chart the study instance is applied to: sc.ReadIntradayFileRecordAtIndex.
- Low-level work related to Open SSL.
- Added ability for users of the SC Exchange Data Feed to add symbols from an Exchange or Index to the Associated Symbol List.
- New Range Bar type added.
- Permanently removed the Weekly OHLC study. That study will need to be removed from any charts which use it. The original name will be replaced with a placeholder name (unkown name). The replacement study to use is Period OHLC-Variable Period.
1625 Release Date: 2017-10-20
- Added a new setting to Intraday Chart Bar Period >> Bar Period Type >> Reversal Bar to support a minimum length before reversal. This is specified in ticks. The format is: Reversal Amount in Ticks-Minimum Length in Ticks. Example: 4-10.
- Added new setting Chart >> Chart Settings >> Market Depth >> Market Depth Combine Increment in Ticks.
1623 Release Date: 2017-10-14
- All of the Renko Bar Bar Period Types have been rewritten. All four types now use a common code base. The Renko Graph Draw Types have been removed because they were determined to be no longer necessary. The standard Candlestick Graph Draw Type is now used instead and functions like a Renko bar for the Renko Bar Period Types. We now later realize that this has the disadvantage of preventing a visual display of the true open and close values. We can restore these separate Renko Graph Draw Types if needed.
When using the Bar Period Type >> Renko Bar, there is no longer any alignment of the first Renko bar Open to the Box Size. Instead the alignment is based upon the true Open price for the trading day when New Bar at Session Start is enabled in the Chart >> Chart Settings. For alignment, use the Bar Period Type >> Aligned Renko Bar instead.
Also, by default price gaps are not filled with Renko bars unless using one of the Gap Fill options in Chart >> Chart Settings >> Intraday Chart Bar Periods. - The old Renko Chart and Renko Chart Enhanced studies are no longer in the main study list and can only be added through Analysis >> Studies >> Add Custom Study.
- Improvements to importing data, to allow the import of data for a symbol which currently has a chart opened for it.
- Additional improvements to the Intraday Data File Management functionality.
- Percent Change Since Open and Percent Change Since Previous Close now use the Percent Value Format.
- Various other less significant development. As we have reported before, the What is New page only reports about 25% of actual development.
- Working on direct integration to BitMEX. The BitMEX data feed now uses our own code rather than an intermediary software program which BitMEX was using.
1621 Release Date: 2017-10-05
- The ability to set a Text Tag on an order through the Trade Window Set tab which is added as the Note field to the Trade Activity Log. You can now filter Trade Activity Log entries by the Notes field which also filters the fills used in Trade Statistics and the Trades tabs of the Trade Activity Log.
- Improvements to the Intraday Data File Management functionality. A temporary file is now used for performance and safety.
- Worked on Alert functionality. Add a new option to include only the user-defined name or alert filename in an alert message along with the current timestamp. This is for more compact transmission of SMS and Twitter messages.
- Corrected a recent problem with subscribing to market data when using the CTS FIX Trading service which occurs under certain conditions.
- Added new ACSIL member functions.
- When Trade >> Show Market Data Columns is enabled, then all of the background coloring configured for the market data columns will now be displayed.

This is also very useful when one Sierra Chart user wants to prepare a Chartbook to help another Sierra Chart user.
- Corrected small issue with the replay control panel when replaying charts that have the same chart Link Number where changing the replay speed was not updating other charts in that Link Number group.
- Low-level changes to the Intraday Data File Management feature to improve its performance and make it safer in its operation.
- Various other low-level development.
1611 Release Date: 2017-09-14
- Chart windows are now destroyed when they are no longer visible to conserve operating system resources and allow for more chart windows to be open at the same time.
- Good Till Date-Time is now supported as a Time in Force for Attached Orders.
- Ability to submit order fills to your account on the Web server for various upcoming reporting features. This setting is in Global Settings >> General Trade Settings.
- Futures options support for CTS. There is additional implementation required in the File >> Find Symbol window for this. Update: This is now complete in the latest revision of 1611.
- Corrected problem with Global Settings >> Customize Keyboard Shortcuts >> Custom Trading Keyboard Shortcuts where when changing the settings for a particular trading keyboard shortcut, this was causing a corruption of other global settings and the settings were not properly applied. It is essential when using this functionality to update to this version or higher.
- Updated the interface to Google historical data due to a change by Google.

- Resolved a problem with freezing when starting a replay using Accurate Trading System Back Test Mode.
- Renamed Bitcoin Data - All Services to Cryptocurrencies Data - DTC.
- Corrected issue where a drawn Volume Profile would not immediately adjust when adjusting it from its corners.
- General performance improvements. Improved a chart data loading performance issue that arose in a recent release.
- The standard bar period Control Bar buttons now also control the TPO Profile Chart study time period Inputs.
- Added new input to the Volume by Price study to control the width the volume bars relative to all visible profiles.
- Added additional support for futures options with the Sierra Chart Exchange Data Feed.
- Gain Capital bid and ask data feed processing changes to process all bid and ask updates on the incremental feed. Previously due to correction of other behaviors with this feed, this was not the case.
- Additional order types can now be set in the Chart DOM Settings for the order entry columns.
- Various issues resolved that were reported on the Support Board.
1599 Release Date: 2017-08-20
- Organized and improved the Volume at Price Threshold Alert V2 study and documentation in order to improve the Inputs and to make them technically accurate.
- Changed Maximum Position Allowed handling for automated trading. When calculating the quantities of working orders, orders which will reduce an existing Long or Short Position Quantity are not counted or considered. Refer to the Automated Trading Management documentation for further information.
- New option to resend Stop Attached Order in the case of increasing child order quantity during an order fill which causes the increase to be rejected. This feature is currently disabled and needs to be tested.
- Various additions, changes and issues resolved from requests on Support Board.
- Increased the number of persistent variables per data type in ACSIL from 5000 to 50,000.
- New Subgraphs added to Numbers Bars Calculated Values study.
- Support for Futures Options with the Sierra Chart Exchange Data Feed. Although this feature has not yet been released on our server.
- SOCKS 5 proxy support which allows Sierra Chart to work on any network which requires the use of a SOCKS 5 proxy. Username and Password verification is also supported. This is configured through the main Sierra Chart Login window, and also through Global Settings >> Data/Trade Service Settings >> Proxy Settings . This is a long overdue feature. This is especially useful in corporate environments. This feature cannot work with TransAct or Rithmic because Sierra Chart does not use direct connectivity for those services and we encourage those services to offer a direct connectivity option. And that option will need to follow the DTC Protocol. This feature allows a user to tunnel all Sierra Chart connectivity through a central proxy server.
- It is believed the issue that some users experienced with freezing of Sierra Chart when starting a replay with Accurate Trading System Back Test Mode, has been resolved. If there is any further issue with this, let us know. We have consistently been unable to reproduce this issue and could find no cause as of yet after extensive code review. Some changes have been made and additional code review will be done.
- Various small improvements and issues resolved with Drawing Tools and documentation updates on the Chart Drawing Tools documentation page.
- Added Last Trade Price Box Outline color setting in the Graphics Settings window.
- Various other development.
1595 Release Date: 2017-08-06
- Interactive Brokers delayed streaming data support.
- New background color settings for Chart/Trade DOM market data columns Cumulative Last Size, Last Size, and Last Price Background Bid/Ask Trade.
- Corrected issue with keyboard shortcuts being nonfunctional arising in one revision of 1592.
- Now when the Chart DOM is not enabled, the text and background color settings in Graphics Settings for the last trade price box, based on bid and ask trades, is now functional. These color settings require setting the Enabled option for these color settings to be applied.
- Using common code for all extension lines so that all study Subgraph settings/properties for the extension lines apply to extension lines for Volume Profiles and TPO Profiles, consistently and fully. Internal performance improvements with the Volume by Price study. This development is still in progress.
- Added new Tools >> More Tools >> Log Drawing Statistics command to log drawing related performance statistics into the Message Log.
- Corrected issue with using the Good till Date-Time setting on the Trade Window, which arose in a recent release. When using the CQG Web API service, the good till date-time is now adjusted to UTC before sending to CQG , as is required.
- There are now 150 Advanced Custom Study Buttons compared with 50. Due to the necessary implementation and for safety reasons, it was not possible to maintain the assigned keyboard shortcuts for the first 50 if they were assigned. Those will be cleared upon an update to version 1594 or higher, and will need to be reset as required.
- Various other development.
1589 Release Date: 2017-07-25
- With the CQG trading platform service, options lookup is now supported through the File >> Find Symbol window. This is necessary to find the correct option symbols to use.

- Corrected some minor issues with the Intraday Data Editor arising in a recent release.
- New Chart Drawing shortcut menu command to add a Ray line which is parallel to a Pitchfork drawing.
- New ACSIL members to request and receive keyboard key and keyboard character events. Refer to ACSIL Interface Members - Variables and Arrays.
1585 Release Date: 2017-07-19
- Added new chart trade menu commands to move Target orders and Attached Stop orders to selected price on chart.
- Corrected small issue with a trend reversal which can occur on first Universal Renko bar of day.
- Corrected an issue with alignment of the Recenter Line on a Chart/Trade DOM.
- Corrected an issue from a recent release with alignment of Color Bar Draw Styles for Renko bars.
1584 Release Date: 2017-07-13
- Corrected an issue from a recent release with the Intraday data editor where the chart would not reload after changes to data records when the editor window is closed.
- With the Numbers Bar study, when Enable Diagonal Zero Bid/Ask Compares, Input is set to No, then when comparing to a nonexistent price level, the resulting percentage will be 0 and/or there will be no color drawn. May general improvements to the Based on AskVol BidVol Diagonal Difference Percentage of Bar Range Text/Background Coloring Method. Fully updated the Numbers Bars documentation to document in detail, each Background and Text coloring method.
1583 Release Date: 2017-07-11
- Added option on the Trade menu for enabling automated trading for individual charts. The default is enabled.
- Added option in Global Settings >> General Settings to set the start of the week to Monday instead of Sunday. We realize, that only the United States and Canada recognize Sunday as the beginning of the week. The international standard is Monday.
- All of the time related Spreadsheet functions now support milliseconds. The documentation has been updated.
- Corrected long-standing problem with the Study/Price Overlay Study when another study is based on it where it would not update its output arrays immediately for new bars added but do that the next calculation. An example of where this would be a problem is when a study like the Study Subgraph Multiply study is based on the Study/Price Overlay study. When a new bar is added to the chart, the overlay study updating was being delayed until the next time the study is calculated. This was due to an incorrect determination of the array size because of the allocated dependent Date-Time array for the study. In the past the resolution to this issue was to select Chart >> Recalculate. This is no longer necessary.
- Updated all of the arithmetic studies to perform calculations at earlier indexes when they are based on the Study/Price Overlay study and also update a special index to indicate where they were updated when the Study/Price Overlay study is based on them or other studies.
- In the case of the LMAX Trading service, when new historical order fills are received from the remote trading server, the connected Sierra Chart clients are automatically notified of this and request the fills.
1575 Release Date: 2017-06-26
- When adjusting a Chart Drawing from ACSIL, if more than one Chart Drawing uses the same LineNumber, only the first found drawing will be adjusted for performance reasons. Therefore, it is not considered best practice to use the same LineNumber for different Chart Drawings added by the ACSIL sc.UseTool function.
- With the Numbers Bars study there is a new Input to highlight and extend nonzero bid volume and ask volume at the high and low of a Numbers Bar. The extension is until intersection with future prices.
- The Volume by Price study has a new input to extend the Volume Weighted Average Price line.
- Corrected an issue with processing the trade quantity/volume for certain exchanges with the Tele Trader data service.
- Various drawing tool improvements.
- Combining of CME trades into the larger original summary trade with the Sierra Chart Exchange Data Feed. This feature is under development still.
- Automatic downloading of historical Intraday data for open charts that are not receiving real-time data when using the SC Data - All Services service.
- Support for AMP Clearing when using CTS.
- For Continuous Futures Contract charts back adjustment changes are now modified through Global Settings >> Symbol Settings.
- Added new sc.BaseDataEndDateTime array to ACSIL which contains the ending date time for each chart bar. This requires setting sc.MaintainAdditionalChartDataArrays to 1 to cause this data to be maintained.
- When using the TransAct Trading service, when there is an order rejection for a new order, in particular an order where a Good Till Canceled Time in Force is not supported, the order rejection was not mapped to the correct order. This leads to a case where the order looks like it is nonresponsive. Instead there was a new order being added to the order list. This problem has been resolved. The underlying problem is that when the TransAct bridge program rejects this type of order, it sets the Trade Account to "0" instead of the actual trade account which causes this problem because it looks like the order is for a different account.
