Ridge's comments about 'horses for coures' also pertinent, depends on market, risk and product (derivatives etc.)
Stop loss is an acquired artform and have posted before on subject so will not repeat myself.
Will add only the following;
1) Most difficult concept of trading. 2) You must have the ability to detach from the individual transaction and see trading as a process over time. 3) You must have the ability to ignore any emotional bridge between your last exit and next entry. 4) You must have the ability to recognise short term frustration is a fundamental component of medium term gain.
Comes down to the majority will never get a handle on stop loss therefore the majority should not regularly trade.
