Expert Advisor Code v42 - Detect Friday Close Time

Dear traders,

I'm proud to announce a new release of the Expert Advisors source code used by FSB Pro.

The new code solves a longtime problem - automatically detection of the end of the Friday trading session. This is important in order to make the Day Closing and the Week Closing indicators working properly.

Friday Close

You see on the above screenshot that the expert closes the position at 23:59 on Tuesday and at 21:59 on Friday.

These indicators doesn't replace the “Day Closing 2” and “Week Closing 2” indicators where you can set different closing times.

The v42 code release fixes a bug that may lead to “requote” errors in MetaTrader 5.

You will receive the update when you start Forex Strategy Builder Professional.

Please test carefully your experts and report all issues you may encounter.

Dear traders,

We are proud to announce the release of Forex Strategy Builder Professional V3.8. This release fixes some noted issues and adds new features requested by our users:

New features:

  • Re-import expert advisor to FSB Pro. Now is possible to re-import back expert advisor created with FSB Pro. It is very simple to do it, just drag and drop your EA on FSB Pro and it will recover the strategy used for creating this expert. You can also do it also from the Strategy menu.

Import an Expert Advisor back.

  • Added Maximum equity drawdown percent sorting and filtering criteria to the Collection page. Now you can filter out the strategy collection using that criteria. It can be also used as a search method for the Generator.

Max Equity Drawdown criteria.

  • Expert Advisors automatically recognize the order filling methods for your MetaTrader 5 broker. The experts correctly set IOC or FOK filling methods.

Fixed issues:

  • Fixed indicators’ first bar for almost all C# and MQL standard indicators. Now the default program sets the first bar for the strategy backtest equal to the bars required from the particular indicator + 1 if the indicator uses “Use previous bar value” option + 2 additional bars. That correction guarantees the proper work of strategies sand experts for all logical rules.
  • Fixed a bug in the EA code when the expert trades higher amount when it bases the trading size on the account percent.
  • Fixed an issue in the Collection page when the program changes the selected collection when the user removes a strategy.


FSB Pro still do not support MetaTrader 5 Hedging accounts. We need more testing in order to provide this feature. We will try to provide support for hedging accounts as soon as we can.

Please test your experts carefully on a demo account first before starting a real trading. We do our best to provide the most reliable forex software in the industry but bugs happen. Please report all issue in the support forum.

Multi Tester

Fixed Bugs in FSB:

  1. Fixed unnecessary additional signal shift of LTF indicators with some logic rules.
  2. Fixed setting of the Editor's page indicator chart Volume color.
  3. Fixed a crash in Data Download page for Windows installations that do not support UTC time zone. This problem was noticed in Windows copies designed to be used in only one country.
  4. Fixed misspelling of PositionPriceDependence enumeration. The option “BuyLowerSelHigher” is replaced with “BuyLowerSellHigher”. The current indicators can used the older option, but we recommend the new variant for the future custom indicators.
  5. Fixed changing values in the Indicator Options dialog by using the mouse wheel.

Changes in the MQL code:

  1. Removed all external prerequisites for the EA: Object.mqh, StdLibWrr.mqh, ArrayObj.mqh, WinUser32.mqh, stdlib.mqh, EasyXml.mqh. Now all you need for trading the EA is contained in the exported file.
  2. The expert loading is faster, which can make the difference in case of recompilation and restart during trading.
  3. Added Min_Data_Bars parameter for the users who want to increase the number of bars loaded by the EA.
  4. Removed the included XML version of the strategy in the code. The strategy creation code is generated by FSB and placed directly in the EA code during the export.
  5. Unified the strategy trading logic code in a single file used in both MT4 and MT5 experts. This improvement guaranties the nearest possible trading behavior in both MT versions.
  6. Fixed a typo in mql indicators option “IsDefaultGroupAll”. The old variant “IsDeafultGroupAll” is still working but deprecated.

This FSB Pro release requires a full update in order to ensure compatibility between the program and the MQL code files.
