If you have a trading plan, you will always know how to act in the market and where you are going to place your trades, take your wins and cut your losses.
Your trading plan primarily consists of one or more strategies with rules that should help you profit from trading.
Having a trading plan makes trading easy and it takes out the thrill, anxiety, and complexity of traiding.
When you don't have a trading plan you'll more likely want to try a new strategy as soon as the one you're currently trading "stops" working.
Most traders will usually jump from one strategy to another every week or month.
So want you want to do is to trade a proven trading strategy, based on price action.
If you continuously jump from one strategy to another in the hope of finding the Holy Grail, you are running on false hopes.
The result of this endless jumping around, you'll lose money.
You should never switch strategies simply because of a short losing streak.
What you need is commitment and discipline if you intend to become a successful trader.
