Gerry,
I agree - it is very different - but defintely nice to not worry about execution or routing as you said. I almost always got my stop price when I was stopped out. The moves are very fast - I had to set up hotkeys with IB so I could have my sell ready as quick as possible - it can move 5 points so quickly. I got burnt a bit today - I tried using stops 5 points below the bid so when it was trending up I could ride the trend longer and I was getting killed. Maybe that worked for a day like yesterday but I think I need to stick to stops 2 - 3 points below the ask. My wins were mainly 2-4 points while I was getting stopped for 5. When I switched to tighter stops of 2 points below ask I did much better.
It really does help to review your trades after the close - My major losses were getting stopped for 5 points a stop during a downtrend trying to catch the bottom. I ended up down about $300 for the day. If I would have avoided those 5 point losses it would have been an up day for me.
