DISASTER TRADE - but not unexpected given my approach and the volatility. Totally caught out by a very quick change in the market and I was unprepared. I didn't have stop in place, I had added a second contract. I wasn't watching properly as was busy on a work conference call. In that time I got a margin call. I tried to let it run as was near resistance. I got a second margin call. In the end bailed. GOOD LESSONS in this loss at it wipes out all the good work and profit from previous weeks.
