I think you guys are just bitching about nothing. If you are scalping dimes, yes you get screwed. It happens. Who cares. Look at the bigger picture.
I personally made $40,000 today trading a few listed stocks. I entered 5-25k market orders. My slippage was 5-25c at a time. On average, it was 15c on 10,000 shares. I gave the guy $1,500 on every trade I executed. It happens. It is acceptable. I deal with it. I like slippage. It makes me know I am right. Rather than complaining, learn to use the system to your advantage. The specialist does not have that much inventory. Throw size at him, and he will run. Penny him and make the spread. There are lots of ways to win.
