Hey guys, I'm going to open futures account to trade ES and since I'm new to futures I have a few questions: 1) I will be trading online and I was looking for the fastest execution. What is a reasonable execution time trading futures online? I deal with high frequency traders and for them it is in the milliseconds... 2) Any opinions on Infinity versus GlobalFutures vs Mirus? I'm looking for $500 intraday margin, ~$4RT commish, free platform, $5k minimum deposit. I hear good things about Interactive Brokers, but margins are high?! 3) Given the ES liquidity, is it common to get bad fills? Thanks and good luck trading to all.
