Me though I have had stoploss hit maybe 5-10 times in 700+ live trades since I began. These are "emergency" sl I put on when scalping that got touched in a breakout - just what they were there for. However, everytime a scalp got away from me without a sl it came back to be a winner. I stop trades manually with my big honkin finger. Maybe I'm just lucky, but I'll take it.
Have you read the "Fallacy of Technical Analysis" thread? Interesting perspectives on sl's, R/R, etc in there....
