I was analysing your 2010-04-09 trade where it gapped up over the weekend. It triggered up to 4 martingale positions, with the last being 81 standard lots. (Or rather 81 times the lotsize of the 1st position).
Your equity before the trade was $208,985.02. The maximum the price went up to 0.8847. The $ drawdown for all 5 positions went as high as -$58,780.49. A relative drawdown -28.13%.
I see that each Martingale position's lotsize is 3 times the previous and at a step of 22pips. The 5th position was 58 pips away from the 4th position due to the gap up and triggered the moment your broker opened for business for the week.
Had you used a broker that opened earlier in the week like IBFX, the 5th position would have triggered at 0.8818 (38 pips from the 4th position) and your drawdown would have been -$83,780.33. Relative drawdown -40.09%
A suggestion is to change your settings to open a subsequent martingale position greater than 22 pips away. Or avoid the 1st position trade at 14:58 GMT+1.
