i got slapped in the face and lost 2 trades in a row. i won my next trade though and i'm back to crushing it. how?

i got slapped this morning lost 0.70% profit from 2 trades. the reason why? i doubled up like a jackass i've learned from my mistake though, and guess what? my fundamentals are still correct and rock solid basically, my prediction of the markets is about 80%, that's my win rate the other 20%? i get slapped, like what happened this morning. by not doubling up though, i can reduce how painful a slap is, so that's where i screwed up i won my next trade and i should be on track to win my current trade as well why is this the case? because my strategy is sound and goes accordingly about 80% of the time even if i get slapped, i still end up going back to winning since the success rate is just naturally so high that's the benefit you get of understanding the market and how it moves
