Quote from candletrader:
The two schools of thought, whatever the timeframe, are:
1) to use small stops and potentially be chopped around until you get a clear winner... somewhat psychologically damaging, some would argue... OR
2) to use large stops to give the thing room to wiggle into a clear winner... but suffer potentially large drawdowns on a string of losers... somewhat psychologically damaging, some would argue...
I guess I'm 3) Use small stops while not getting chopped around while going for outsized moves.
Whichever school you choose, the size of the stop doesn't really matter if psychological damage is the actual issue.
