New EA Based on hedging and martingale

Hi, developers!   I have an EA (MT4) I´d like to develop. As for today, on demo basis it always loses money but, anyway; I´d like to give a try.

The strategy is pretty simple and nothing new, as it´s a mix of hedging with martingale, and it just need to "watch" positions´ profits. Each active trade has two active positions at once. It has 17 parameters regulating openings, closings, trailings, spreads and general settings. It must work with many pairs at once. 

I need it in maximum 5 days, and I may pay 150 dollars.

Thanks in advance.
