Thank you for the detailed description. It will take about one week to code the EA. I have one question only. Why do you add spread to short pending orders and to the stop loss for long orders? Shouldn't these levels be calculated based on the bid?

I add this because the previous platform (marketiva) i use they will have spread on both side. Which 4 pips for long, 3 pips for short. So when i close the contract overall is 7 pips. Currently i using fxopen, they only charge on long. So i am still confuse on this.

I think you point is correct. There are no need to add spread on the short pending order and the stop loss for long order. Sorry for the confusion.
