Quote from logic_man:
No, the system includes stops so being stopped out is part of it. Also, since you don't know where the market is going to stop moving against your trade position you got stopped out of, saying that I got my ass handed to me is unsound reasoning. Let's say I'm in an ES position at 1300 with a 10 point stop. I get stopped out on that trade for a 10 point loss and the ES is now at 1290. I then get another trade trigger in that direction, only it takes another 15 points of decline to get it, so I am entering at 1275. I enter and make and 10 point gain before exiting at 1285 because of price action, so now I'm at net 0 points for the two trades minus some commission costs. If I had stayed in that initial trade, I'd be down 15 points with absolutely no guarantee that the ES would make it back to 1300 within any reasonable timeframe. Why put myself through that kind of trade? I, and every trader, know with 100% certainty that I am going to have losing trades, so why try to fight the inevitable by pretending every trade will eventually come back and make a profit? It's just a form of wishful thinking.
So, you can't just assume that someone gets stopped out, then re-enters immediately or almost immediately and goes on to capture the initial move they were waiting for. In fact, if you just got stopped out, on what logical basis would you immediately re-enter the trade anyway? Price was clearly telling you you were on the wrong side of the market. Often the market will continue against that position before making the move you wanted and that continuation can be of significant size. I've been stopped out before "waterfall" drops of 15 ES points in a matter of a few minutes or hours, then gotten trade signals to go long again and made a profit, so the scenario I described is not just hypothetical.
Value investing is such a completely different animal that I'm not seeing the relevance to this discussion, frankly.
Nor am I saying that using stops will guarantee that a trader is successful, only that using them doesn't preclude success. Big difference. When I started out and was a losing trader, I used stops and I use them now, although differently, and I'm making money, so clearly that's not the important variable in the entire equation.
