John Henry had this problem in real life. When he took positions other traders pushed prices in the opposite direction to force him out with a loss. He had to start to delay annoucing his new positions in his letters to his clients.
Schizo will not have that problems as many times he will be already out again before the funds were able to get in. LOL.
Monroe Trout, featured in New Market Wizards, almost never used actual stops placed in the market, but instead used alerts when price reached a certain level and would then evaluate to get out or not. Probably not a good idea for most day traders as ES can move fast, especially these days.
I'm probably paranoid, especially since I'm trading small size, but I've been stopped out at the exact high/low so many times that one may start to wonder.
