Exactly, because the definition of a stop is: the place where the profits should be protected maximal while reducing the losses to the minimum.
But that would mean that you can correctly forecast the path of the trade... How is your success rate in predicting the direction of the trade? And over which timeframe-lengths does it work best?
And what do you do immediately after entry when the trade runs against you? You get stopped out... multiple times makes a big sum... But I get your point: a good planning for the entry point is a good thing to do, right.
Knowing the definition is important. Next challenge is trying to apply it as good as possible. So first you need the knowledge to know what to do, and next the knowledge to do it. I am happy with my success rate because at the start is was a "suck"sesrate.
No, getting stopped out all the time means your system entries are not good. If you have good entries you have more possibilities to try for free as you might be able to close a bad trade before losing money.
