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.

    • Added a Difference line to the Ask Volume vs Bid Volume study. This study also now supports Time Offset settings in the Data/Trade Service Settings window.
    • Added support for the DTN IQ Feed data service. For more information see the DTN IQ Feed page.
    • There have been major internal changes with this version to support additional data/trade services. It is considered a pre-release. It should only be used by experienced users or those who wish to use DTN IQ Feed. It is recommended that you install this version in a folder different than where your current Sierra Chart is installed. If any problems are encountered, please advise support about them.

    • Added options in the Chart Settings window to hide the Time and Values scale areas.
    • Corrected some bugs concerning the "TPO and Volume Profile" study. Additionally, the study now has the capability to extend VA lines. It is strongly recommended that the TPO and Volume Profile study is not in any default chartbooks on the first run of Version 87, please be sure to remove the study before you upgrade Sierra Chart.

    • The "TPO and Volume Profile" study has been significantly improved. As a result, to use this study you must remove and re-add the study. It is strongly recommended that the TPO and Volume Profile study is not in any default chartbooks on the first run of Version 86, please be sure to remove the study before you upgrade Sierra Chart.

    • Made a change to the Time and Sales data structure used by custom studies. The date of the record is now stored. This change requires custom DLL studies that use Time and Sales to be recompiled to work with this version. If you are using Time and Sales related studies, please wait until the developer of those studies updates them to support this version before installing this version.
    • Corrected a problem with Point and Figure charts that would cause an abnormal shutdown
    • Added Ask Volume vs Bid Volume Study. (Special Feature)

  • 84

    • Added a new chart type: "TPO and Volume Profile" (Also known as Market Profile). This can be found under Analysis >> Studies on the menu. Currently this is made available at no extra charge to all users. At some point in the future there will be an additional charge for it. The Price Range Increment input changes the price range increment for the profile. The default is currently 1, you may have to adjust this based on the chart you are viewing.

    • Corrected a problem logging into the software in some special cases.
    • Corrected a problem where a study would not be moved to region 1 when the "Display as Main Price Graph" option was enabled or when setting a Spreadsheet study as a system or alert. Additionally, the Spreadsheet study has a new input to allow a system or alert to be displayed in any region.
    • Corrected a problem where out of range inputs were not automatically corrected after closing the study settings window.

    • Restored the MyTrack Dial Data Database support.
    • Corrected a problem where IB daily volume messages were not being processed correctly. This prevented the display of the cumulative daily volume in the current quote window. This fix also provides slightly better tick and volume counting through a special algorithm by treating volume messages as trades in special cases. Please provide feedback so we can better improve the algorithm.
    • Added 2 new commands to the Spreadsheet menu. When you select any cell along a quote line on a Spreadsheet, Open Historical Chart and Open Intraday Chart will open the symbol for the quote line as a Historical or an Intraday Chart respectfully. If the Chart is already open, the Chart will be activated instead.

    • Added support for customization of the Toolbar. To customize the Toolbar, select Global Settings >> Customize Toolbar on the menu.
    • Added support for customization of the Chart Header. To customize the Chart Header, select Global Settings >> Customize Chart Header on the menu.

    • Corrected a problem with the storage and display of bond futures prices when using the TransAct service. If you have been charting bond futures, it is necessary to delete the bond futures chart data files before opening them. For instructions, see Deleting a Chart Data File.
    • Added new members to the custom DLL study structure that provide the bar index and y position of the active tool.

  • 77

    [Link] - [Top]
    • Corrected a problem where the scale may have gone to 0 when a study did not cover all of the displayed bars due to not enough data the study required.

  • 76

    • The Preserve Fill Space option on charts has been changed to Lock Fill Space. When this option is enabled, the fill space on that chart will not change due to any new data or scrolling. When this option is not enabled, you can modify the amount of fill space and the fill space will be filled in as new data arrives. You can temporarily toggle this option by holding down the Ctrl key. So if the Lock Fill Space option is on, you can hold down the Ctrl key to modify the fill space, and if the Lock Fill Space option is off, you can hold down the Ctrl key to temporarily lock the fill space. You can easily turn this option on or off by using the Chart >> Lock Fill Space menu item. This option can also be found in the same place that the Preserve Fill Space option was in the Chart Settings window.
    • Corrected a problem with the Global Crosshair where the cross-hair on charts other than the active one may not have been precisely on the corresponding bar.
    • Corrected a problem where studies such as ADX, MACD, and Bollinger bands, may not have been displayed when using old chartbooks or study collections.

  • 75.2
