I see that you're running 2 Megadroid instances on the same account. Possibly the second one with GMT+1. The first one with RiskLevel 0.3 and the second RiskLevel 0.2. Using 50% of your margin for one trade window is quite high.
Had you used only 30%, you would have gotten out at breakeven or +1 pip profit at 2010-04-23 08:00 instead of margin calling.
