The term for your style of trading is called "cannonballing". You are a ticking timebomb. You WILL blow out. I suspect you cleared IB because a major European futures clearing firm like Fimat, SG, EDFMann, M-P, DB, etc. would never let you pull that crap. Remember what happened to Griffin Trading and their rogue Korean trader Park trading Eurex Bunds? He was a cannonballer, same as you. Kept adding to his "winning" position, just like you.
