I read with interest a fairly detailed article about the turtle traders in the 1980's and their strategy of attempting to catch big trend moves in different markets. Initial stops would be 2x an exponential average of ATR. It seems to me their approach to the market was to suffer through many small losses waiting for a few "big" trades. Does anybody know what the typical win/loss ratio was for these guys? Must have been <20%. Seems like a psychologically challenging market approach.
