What Is New
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.
- Holding down the Ctrl key now preserves the fill space when scrolling a chart.
- Changed default vertical line spacing for intraday charts to 1 day.
- Fixed the issue with not being able to set the vertical line spacing settings as default.
- Added DynamicNameExample to the end of studies.cpp as a demonstration for dynamically setting the name of a subgraph in a custom DLL study.
- Redesigned the Data/Trade Service Settings window.
- Corrected a problem with TransAct that may have prevented some symbols from being available.
- Double-clicking in the price scale area on a constant range chart re-centers the chart.
- Added a new Add Study window that supports browsing the available study functions in new or updated custom study DLLs. This can be found by pressing the "Add Custom Study..." button in the Technical Studies window.
- Custom study DLLs can be built to support the new Add Custom Study window that shows available functions in a DLL. For more information about how this is currently supported see the Advanced Custom Study Interface and Language documentation.
- Updated Sierra Chart so that the automatic TWS login feature works for newer TWS versions.
- Added a vertical grid line spacing setting. This is available in the Chart Settings window. By default, the vertical grid line spacing is 1 month for historical charts, and 1 hour for intraday charts. If you have been using the day/month breaks option, then you will need to change the vertical grid line spacing to your requirements by selecting Chart >> Chart Settings on the menu.
- Made improvements to the TransAct data service interface.
- Data Source Settings is now called Data/Trade Service Settings.
- Fixed scaling issues related to Same As Region and DrawZeros.
- Fixed backward compatibility with the Horizontal Line study.
- Added Reset Scale to the Chart menu.
- Internal changes to scaling.
- Updated the Horizontal Line study.
- The Start TRANSACT command on the Trade menu now functions correctly. However, the latest TransAct software is required to support this.
- Added support for the TransAct trading and data platform.
- Improvements to interactive scaling on automatic scaling. Padding can also be added on graphs with User Defined Scaling now. Double clicking the price scale area resets padding to zero.
- Fixed problem with incorrect scaling on charts.
- Fixed value labels on subgraphs to not draw outside of the price scale region.
- Fixed drawing of the main price box so that it draws on top of other price labels, and does not go outside of the price scale region.
- Fixed Snap to High/Low function.
- Fixed Copy and Move Line/Text.
- Corrected a problem with the IB automatic login feature due to changes IB has made to their TWS software.
- Added arrow trendlines.
- Added auto-coloring for study subgraphs. This automatically uses the primary and secondary colors to color the subgraph based upon the slope.
- Added a Graphical Displacement setting to studies. This setting can be accessed at the bottom of the Subgraphs tab in the Technical Study Settings window. This supports negative displacement.
- Added GraphicalDisplacement member to the s_sc struct for DLL studies.
- Renamed GetCorrespondingIndex to GetNearestMatchingDateTimeIndex in the s_sg struct for custom DLL studies. Previously using a negative ChartNumber would not cause synchronization between the two charts. This has been changed so that now a negative number WILL cause synchronization and a positive ChartNumber will not.
- Added the functions GetNearestDateTimeIndex, GetNearestCOleDateTimeIndex, GetIndexForMatchingDateTime, GetIndexForDateTime, and GetIndexForCOleDateTime to the s_sg struct for custom DLL studies.
- Updated the Volume study to use only one subgraph instead of two.
- New Subgraph settings tab in the Technical Study Settings window.
- Minimum line width for study subgraphs is now 0 instead of 1.
- Light colors are no longer inverted for printing if the background color of the chart is also a light color.
- The Trade Window has been redesigned and now occupies less space.
- When using Extending Trendlines, the point of convergence is more accurate.

- Added the input value type MOVAVGTYPE_VALUE.
- Added TextInputName to the s_sg struct for custom DLL studies.
- Added RangeBarValue and RangeBarType to the s_sg struct for custom DLL studies.
- Added the Fill Top and Fill Bottom subgraph styles. To use these styles, you must first have a chart with at least two subgraphs. Set the draw style of one of the subgraphs to Fill Top, and another to Fill Bottom. In order for this style to show up, the subgraph with the Fill Top draw style must have values greater than the subgraph with the Fill Bottom draw style. The color of the subgraph with the Fill Top draw style will be used as the fill color.
- Added the ability for DLLs to use SUBGRAPHINDEX_VALUE and YESNO_VALUE input value types.
- Added a Fibonacci option to color lines the same as the trendline color. This can be found in Global Settings >> Tool Settings.

- When using a tool command such as Erase Line/Text or Adjust Line, lines and text can now be selected by simply clicking on them with your pointer.
- Made changes with downloading of IB backfill data.
- Improved the Range Bar Charts feature. There are two types supported. If the Range Bar type 2 option in Chart Settings is enabled, then a new bar is created when the range has met your setting whether or not trading continues within the range. Otherwise, a new bar is only formed when trading moves beyond your specified range.
- Added the Dr. Andrew's Pitchfork tool (median line tool). This tool can be found under the Tools menu. To use this tool, simply select 3 points by clicking on the chart. The first point represents the starting point of the extending trend line. This trend line is drawn between the 2nd and 3rd points. Parallel lines are drawn above and below the median line starting at the second and third points.
- Note: To get the desired effect, point 1 should be left of points 2 and 3. Otherwise, Sierra Chart will correct this error and will not allow you to draw a pitchfork in the negative x direction.
