https://fxdreema.com/shared/ux0Lp1N7d it's simple and no changes are made to Risk, SL or TP.

Hello, I have seen something I can not explain. In my EA I defined parameter Risk, SL and TP. Risk was entered 0.0567, SL was 0.2 and TP 100.0. In a Buy or Sell block I use Risk % of balance - so 0.0567 (No upperlimit set), Stop-Loss mode is % of price - so 0.2 and Take-profit mode is % from Stop-loss.
During my backtests with a 100K account the profit/loss money amounts are all around 500/600 (+/-) which was what I expected. But someone else got Trade losses of 5000-6000(+/-). I am confused. 100000*0.0567 is indeed 5/6K but in my backtest I got position values that were much smaller. So what is the position value on a 100K account with the values in my example: Risk 0.0567, SL 0.2 en TP 100. How can it be different ?

@jstap said in Library Studio:

how is your global variable set? If it's not it can't return true.

My global variable is set by another EA - that one is set , so TradeActive is set to true. My Print(ReturnCheckVar,ReturnTradeActive) shows true,true in my Experts tab. Also my printf(ReturnRalph) shows true. Therefore I don't understand why ReturnRalph in my EA does not have the value true.

It's set to the value of TradeActive (see the code in the Function Global_Check_Trade_ActviveLocalEA)

I think I am missing the point of your question (due to lack of knowledge). In the EA I have the variable ReturnRalph as boolean defined. I defined ReturnRalph as boolean in the Custom Fucntion GlobalCheck_Trade_ActiveLocalEA as shown on the screenshot. What is missing that allows a proper return ?

Unfortunately the variable set in my function is not passed on to my EA:

My printf in the function below says TRUE. The check in my EA gives false for variable ReturnRalph

Ah you use a Custom Function named CalculatedLotSize where you pass the value of slPoints to a variable named calculatedLot - which is then available in your EA. Correct ?

This is how I used in in Sudio and then called it (see previous screenshot)

Ok, so apparently that should work although it does not seem to work for me. In your example, you show calculatedLot as a double in your FDX EA, right ? I don't see this exact value in your previous screenshot but I gather thery are named EXACTLY the same ?

OK, I understand that you send variable values from your Custom function to the Custom Block (code in Area A). I meant sending variable values to the EA in FXDreema where you used a Custom Block.
