Hello jcl,

thanks for your response.
I tried to figure out a practical solution with your answer for the problem that i can trade manualy with activtrades at DAX 1 Point for 0,25€ but with Zorro its not possible at the moment.

"A mini lot is 10 times higher than a micro lot, so make sure that this variable is correct for your account."
Do you mean i have to look up ActivTrades Settings? Aren't these the same as when im trading manualy (where smaller position sizes work)?

"For trading a certain amount of money, use Margin, not Lots."
Margin in the code is for FXCM and Activ Trades the same: Margin = 0.5 * OptimalF * Capital * sqrt(1 + ProfitClosed/Capital);
How does this produce a different result in positions size if both codes are the same?

Thanks for time and Best Regards

Leon
