Version 4.2.5 Released

Postby Avarin » Tue Jan 05, 2010 3:08 pm

An upgrade to Version 4.2.5 is now available, containing a number of important fixes to the latest release. The following primary changes were made:

* Correction to random() formula to ensure thread-safe processing. A threading issue was found in the random() formula that was causing errors in specific cases when used with multi-core processors. This has now been corrected.

* Multiple revisions to memory handling to improve efficiency. Some optimization was done to improve efficiency and stability when running StrataSearch against larger sectors and/or large evaluation periods.

* Revisions to script processing to improve stability. When scripts such as the Stocks & Commodities plug-ins were being used, a caching mechanism being used was using large amounts of memory and causing program errors on some machines. This has now been updated to create better program stability in these situations.

* Correction to potential error in Monte Carlo Analysis. In specific situations, and error was causing the Average Trade Return in the Monte Carlo Analysis to incorrectly display as -1.00%. This has now been corrected.

* Force period() to be run within symbol() when used together. An error was discovered when using the symbol() formula within the period() formula. This error can be solved by instead placing the period() formula within the symbol() formula, and StrataSearch now requires this arrangement when using the 2 formulas together. This scenario does not exist in any pre-installed trading rules or any of the Stocks & Commodities plug-ins, and should therefore affect only a small number of users who have programmed such rules.

* Prevent volume requirement when running ASCII price imports. When importing prices via an ASCII import, Volume had been a required field in the layout. This requirement has now been removed, allowing price imports without volume.

To install the program update, users can use the Help > Check for Updates menu from within StrataSearch. If any problems are encountered using this method, users may alternately download and run a manual upgrade from:
