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.
-
551 Release Date: 2009-12-23
- IMPORTANT UPDATE: Corrected an issue with the new Chart Values window where when it is partially offscreen, it can cause high CPU usage. Therefore it is important that all users update to this version as soon as possible if you experience this issue.
- Cut Bar at Session Start in Chart Settings has been renamed to New Bar At Session Start. It now applies to all types of bars including bars based upon a fixed time. This means that at the beginning of the trading day as specified by the Session Times settings in Chart Settings, the bar will begin exactly at that time. Generally, this option is useful when you have a time period per bar that does not evenly fit into the time span of the defined sessions.
- Added a list box to select the data server to use for services that use Sierra Chart's own data servers. The servers are listed based on location: North America and Europe. This list box is found in File >> Data/Trade Service Settings for the applicable services. It is a good idea to check this setting, if it is available for the service you are using and choose the server that works best for you. If one server is not available, automatically Sierra Chart will use the other server. This simply indicates the default server to use.
- Various other low-level improvements.
-
549 Release Date: 2009-12-18
- Updated the Patch Data functionality to specify start and end date/times for the range of data to use for patching from the source file.

- Various other low-level improvements.
-
548 Release Date: 2009-12-15
- Corrected a problem from a recent release where extending trendlines would move slightly when they are cut. This has now been solved.

-
546 Release Date: 2009-12-6
- Implemented the Maintain Same Quantity For OCO Group Orders command on the Trade Window Settings (S) menu.

-
508 Release Date: 2009-09-30
- The automated trading logic in Sierra Chart has undergone many internal improvements and some logic changes. The changes are described here. In this list, when we mention a "variable", we are referring to both the Spreadsheet System for Trading study input with that name, and to an ASCIL variable beginning with "sc.".
- When calculating the position combined with working orders quantities, we no longer distinguish between child orders and other orders. They are all considered independent orders. Although, when we calculate the quantity of orders that can Exit a position, we continue to look at only orders that reduce the size of the position. However, we count them all as if they are independent orders without distinguishing whether they are children or not. For example, if you have a long position with a quantity of 1 and you have 2 sell orders (stop and target) with a quantity of 1 each, the combined effective position will be -1. However, there is still proper interpretation that a long position exists, with Exits and anywhere else a position is important.
- The Entry logic has been changed so that a long or short entry cannot occur if there is a long or short position respectively, independent of any working orders. Unless Allow Multiple Orders in Same Direction is enabled. Working orders are also calculated and combined with the actual position to see if an entry is allowed or not, as always.
- Reversal Logic: A reversal cannot occur unless a position in the opposite direction actually exists. A working order that can create a position in the opposite direction, is not sufficient. When calculating the quantity for the reversal, we look at the current position quantity and the quantities of orders that can exit the position only. We do not consider working orders that can increase the size of the position. If you have the option to cancel all working orders upon entry, enabled, then only the position is considered.
- A new variable has been added to cancel all working orders upon a trade Entry: CancelAllOrdersOnEntriesAndReversals. This replaces the variable to cancel all orders on a reversal. The default for this is true.
- A new variable has been added to control allowing an Entry if there are working orders: AllowEntryWithWorkingOrders. The default for this is false. In other words, if there are working orders, a trade entry cannot occur. This also applies to Reversals as well.
- The automated trading variable MaximumPositionAllowedInSameDirection has been renamed to MaxPositionAllowed. This is for both ACSIL and Spreadsheets. It will now apply whether Allow Multiple Orders in Same Direction is true or false. It also will be compared to the actual position and to the position combined with working orders quantities. These changes will create a more expected result and provide a safer automated trading environment.
- There has been some reorganization of the study Inputs for the Spreadsheet System for Trading study. It is critical that when you upgrade to version 508, that you review all of your input settings to make certain they are correct.
- Support for writing trade signals to a text file to be used by another program for trading, has been removed from the Spreadsheet System for Trading study. The reason for this is now that the trading capability in SC is much more advanced, there's no longer a need for this kind of capability. Also it has created confusion for some users because this option was enabled by the user when it should not have been. Additionally, how the SC auto trade logic applies when using an external program, can be very complicated. It is something we just simply do not want to support. We also are going to be expanding support for additional trading platforms to provide greater connectivity, so there no longer is a need to use other trading programs.
- The internal auto trade management processing is much more efficient and organized. The code for ACSIL Trading and Spreadsheet Trading is now 100% common.
- The Trade >> Trade Service Log now only shows trade signals that are ignored and the reason. It does not show trade signals that are followed and result in an order. You can monitor those through Trade >> Trade Activity Log Or Trade Orders Window.
- The automated trading variable AllowMultipleOrdersInSameDirection has been renamed to AllowMultipleEntriesInSameDirection. This is for both ACSIL and Spreadsheets. For all of the auto trade variables and the current names, see the Auto Trade Management documentation page.
- It is critical that when you upgrade to version 508 or higher, from a prior version, that you test your auto trade system in Trade Simulation Mode, whether implemented using ACSIL or the Spreadsheet System for Trading study, to be certain that it functions properly. You will need to make any appropriate changes based upon the above described changes.
- The automated trading logic in Sierra Chart has undergone many internal improvements and some logic changes. The changes are described here. In this list, when we mention a "variable", we are referring to both the Spreadsheet System for Trading study input with that name, and to an ASCIL variable beginning with "sc.".
-

-
506 Release Date: 2009-09-22
- Corrected a problem with Trailing Stops, and made other low level improvements. We continue to recommend that you use trailing stops only with a simulation account. We did do testing with TD Ameritrade and Transact. The trailing stop functionality worked as expected.
- A Visual C++ Express Template project has been provided. For more information, see this support board subtopic.

- Added the Extending Rectangle Highlight tool. This tool can be selected from the menu under Tools >> Highlight Tools >> Extending Rectangle Highlight.
- Fixed issues with using secondary colors and possibly the color arrays for subgraphs 32 and higher in the ACSIL. This issue was a result of the change when the number of study subgraphs was increased from 24 to 40.
- Added an Apply button to the Study Settings window when changing the settings of a study directly from the chart.
- Updated the behavior of mouse pointer input on the Chart DOM so that the input is always accepted exactly where the mouse cursor is over when the mouse button is lifted.
-
502 Release Date: 2009-09-21
- Corrected a problem with ChartDOM order entry where the order type may not always be according to your settings when entering an order from the bid column. This problem arose in version 501.
- For the time being we have restored the old Chart Values window until a possible problem with the new one is resolved involving high CPU usage which appears to be related to complex interaction with other windows.
-
501 Release Date: 2009-09-18
- Added the study named Color Background Based on Alert Condition. This works identically to the Color Bar Based on Alert Condition study except that it colors the background instead.
