The past couple of weeks I've been trading on different demos from different brokers. Been able to 1x one e-mini contract of S&P 500 in about ten to twenty minutes with about ten to twenty trades. My position is only open for about one to five seconds, because all I'm doing is catching bounces on a one-minute timeline. The odds of me blowing up my account in five seconds is virtually nonexistent so I'm thinking $1,500 $2,000 should be enough. I have no plan to increase the size of my position beyond one contract because about 15% of my orders (I buy the bid and sell the ask) are not getting filled when I need them so adding another contract would be futile. I've been trying out the TradeStation, ninja trader, amp and Tradovate, but prefer TradeStation. I'm also looking for the best futures commodity to get in and out within one to five seconds?
