EA MARTINGALE + Trailing STOP

Recently I ordered an EA which works with martingale strategy + trailing stop but I've haven't had it optimized. I'd like to contact with someone who has optimization experience and can optimize for me two different currency pairs. I'm currently thinking on translating from mql4 to mql5. Would it be better to optimize on mql5? if so, you could do both of the tasks if you wish, and had the skills. Price of the task is just for optimization. If someone wishes to translate it too, we'll speak about that further on. 

Optimization with tick data and being able to proof quality of modeling.
