Hi
I may be wrong but it seems you have there is an error in the instructions. Sorry if I'm wrong. Really for the SELL and BUY price must closed BELOW trigger lines in both cases?
So, I like your task and if you answer me, I will try to send you a free trial version as soon as possible. In any case, if you will not like my work, you just not award me your project. Thank you. Sincerely, Sergey
