A few months ago I switched from Lightspeed to IB for daytrading stocks. I've used IB in the past for futures. The first thing I did was change the 'stop' order type from the default "double bid/ask method" to "last". I didn't see any advantage to the double bid/ask method. But recently I've had a couple of really bad fills so I'm second guessing myself. I know slippage is part of the game when daytrading stocks, and all n all my fills have been ok with IB. Do any of you use the 'double bid/ask method' for your stops? Any advantage/disadvantage with it? Thanks ~Mike
