Jon, Herm,
I played with the simulator some yesterday. It was fun....sort of a stock market slot machine.
Unfortunately, I am inclined to agree with Jon as to how well it really simulates the market, and what happens to your executions if you were really trading that way with it. I was wishing I could figure out exactly what day and time it was simulating, because I would like to put a 5 minute, or 1 minute chart up (I have IQC-Real), and enter my trades off of it. I tried with GTW, and I know that it was not simulating off of Friday's action. In fact, I think it was several weeks old, because that was the last time GTW was up in the 70's.
Fun toy, but I sure wouldn't bet the farm on it.
I agree with your comment about options specialists backing off. In fact, I've watched them doing it for years on the lightly traded options. I usually just pick a price between the bid/ask to sell at, and let it hang there. Eventually they either bite, the underlying stock moves, or I don't trade that day. Sometimes I cancel, and come back later at the same price. They love to get you chasing, and will dangle the price in front of you time-after-time, if you do.
