A person takes a trade after being 100% sure to hit the target but uses the SL nevertheless!!!!
Sir,I hope you understand what is a "trading system" and what is "backtesting".
While preapring a system,one has to put in the exit strategies.These exits may be losses,or winners.
Now you put your system in the language of the software which it understands.
Your next task is do a backtesting.Why?
Bcz by backtesting you can make out that how much successful a system was in the past.
If a trader sees that his system has been X% successful,after discounting the losers,he will be sure of X% that his trades will be successful.
Now when he is 100% sure that his trades will be successful,that means what? That means,his system is indicating him that it has been 100% successful in all the trades.Means zero "drawdown".Means his exits are all winners.Means no stoploss(initial,not trailing).I'm still search of a 100% winning system.Did you find out? Congrats.Now.....
