Hey Jose,
Glad to hear from you.
1. I would use 3 lots so if the EA hits the SL it would be below 1%.
2. What do you mean by ”high new”?
3. The EA does not use martingale: it adds to the position if there is a new signal. However, if you want to avoid the adding just set the entry to 3 lots and max position to 3 lots, so it won’t add on the same directional signal.
4. Abour the backtesting make sure to use a smaller lot and spread of 2-3 pips (not the weekend one)
