Thank you for the reply. I was doing just that and im coming back with more information. It seems the part where Risk_Percent is divided by 100 gives me back 0 in the print. If I change the risk to 100 then it gives me 1. It doesnt seem to want to give me a decimal though. I will check on the lot minimum but I think the above is the reason for the error. Still a min and a max are not bad things to program in. I will change it to equity. Why would I have to check the free margin?

Thank you for the reply. I got it working by doing Risk_Percent*0.01 instead of Risk_Percent/100. Dont know why one works and the other doesn't, they both give the same answer. If I made the Risk_Percent a double I wouldn't be able to change it from the input box right? It would always be a fixed value? I want to implement a special trailing stop but im having a little bit of difficulties with it too. I want it to start a trailing stop once it gets to X% between OpenOrderPrice and Take_Profit. Could you take a look at it please. The parts in bold...

I will attach the EA. Everything thats a print I put in trying to trouble shoot it. I noticed that the OrderOpenPrice() in the Buy Logic isnt the same as the open price when backtesting. Thank you for taking the time to look at it. {file}

Hi cyber1. Im not getting anymore of the errors and I got it to trail the bid/ask after reaching the start point (BEPoint) as you put it. I do have a question about your code though. The part that calls the Trailing_Control is only activated once per bar? Which means the Stoploss will only be updated once per bar?
