How can you tell the right entry points from the wrong ones?

The hardest thing about trading is distinguishing the right trades from the wrong ones. It often happens that you analyzeyou are a chart, then hoppa - you see the entry point,you enter, wait, and in the end it turns out, at best, a meager profit accumulates and then a stop loss, or a stop loss immediately. And all because the wiring was wrong, the entry points were wrong. And there can be many such entry points. And they will take your money. This is because you can’t tell the difference between entry points that will bring you a tiny profit and then a stop loss from those that will bring you a mountain of profit. And, perhaps, there is no chance of distinguishing the correct entry points from the incorrect ones; the trader is doomed to catch stop losses.
