Expert traders are well-versed in the art of carrying out extensive technical analysis. They may have a working knowledge of different trading strategies, but they usually settle on a few strategies that they have found to be successful on a consistent basis.
You should approach trading the same way. Having well-laid out rules that govern when you enter and exit trades keeps you from making emotional decisions. Remember, gut decisions bring the highest losses as trading is never a sure game. Even after using trading strategies, the outcomes may at times go against you.
