OK thanks your for your explanation, but let me explain one thing and after we can close this post. Fxdreema has only two parameters: delta and intial lot . Usually I calculate the initial lot based on margin required and max drawdown I expect for each operation. After this I can undertand your formula how works.
if I have 1000 $ of balance and 500 of delta , step=2 , initial lot is 0.1 next lot is 0.2, this means that i have to wait 1500 $ to move to 0.2 . Correct?
Of course if my platform crash and I have 10000$ of balance I can't start again with 0.1 as lot this would be a lower risk respect to 1000$ , for this reason in the in the fxdreeema ON INIT i calculate the right initial lot and delta (balance /2 for easy way) to take my risk the same.
