Traders Make a Mistake in Finding Entry Points

Traders in general are good at finding entry points, right? What a lot of traders make a mistake in doing is where and when and how they place stops and targets. You have to be realistic with your choices; whenever i enter a trade, i'm not thinking about wins and losses,. When i enter atrade, i'm thinking about willdom does the market have a higher probability of going this way before it goes that way? It's important to kind of know that balance.
