This is post #1 about fxdreema - 

--------------------------------------

That is not your code. It is generated code by the fxdreema code builder, and most code builders are all know for producing questionable code.

The reference below is from another forum thread so point (2) and some of point (3) is not appropriate for you case, but point (1) is definitely relevant.

1. EA builder, EA Builder Pro, EATree, Etasoft forex generator, ForexEAdvisor Forex Strategy Builder, ForexEAdvisor, ForexRobotAcademy.com, FX EA Builder, fxDreema, Forex Generator, FxPro, Molanis, Octa-FX Meta Editor, Online Forex Expert Advisor Generator, Strategy Builder FX, Strategy Quant, Visual Trader Studio, MQL5 Wizard, etc., are all the same. You will get something quick, but then you will spend a much longer time trying to get it right, than if you learned the language up front, and then just wrote it.

   1. Since you haven't learned MQL4/5, therefor there is no common language for us to communicate.
      If we tell you what you need, you can't code it.
      If we give you the code, you don't know how to integrate it into yours.
      We are willing to HELP you when you post your attempt (using Code button) and state the nature of your problem, but we are not going to debug your hundreds of lines of code. You are essentially going to be on your own.

   2. EA builder makes bad code counting up while closing multiple orders.
      EA builder makes bad code Bars is unreliable (Max bars in chart), volume is unreliable (miss ticks.) Always use time.
      EA builder makes bad code, not adjusting for 4/5 digit brokers, TP/SL and slippage.
      EA builder makes bad code, not adjusting for ECN brokers. pre-Build 500)
      EA builder makes bad code, not checking return codes.

   3. EATree uses objects on chart to save values — not persistent storage (files or GV+Flush.) No recovery (crash/power failure.)

   4. FX EA Builder makes bad code, not checking return codes.
      FX EA Builder makes bad code, loosing open tickets on terminal restart. No recovery (crash/power failure.)
      FX EA Builder makes bad code, not adjusting stops for the spread.
      FX EA Builder makes bad code, using OrdersTotal directly.

   5. FOREXEADVISOR STRATEGY BUILDER makes bad code, non-updateing global variables.
      FOREXEADVISOR STRATEGY BUILDER makes bad code, compilation errors.
      FOREXEADVISOR STRATEGY BUILDER makes bad code, not checking return codes.

I do not know ... because if you use it so you should manually fix everything related to your EA, for example:

• The checks a trading robot must pass before publication in the Market - the article
• Solving Automatic Validation Problems Arising During Product Submission in MQL5 Market - blog post

... or ask someone in Freelance to fix it for you ... but if you use Freelance so why do you need fxdreema?

What part of “but we are not going to debug your hundreds of lines of code. You are essentially going to be on your own” was unclear?
