Wish you all the best :)
I am too a human being and we all do mistakes. But what is important, is to learn from them so as we do not repeat them. This was a while ago and looking back at it now, I would've clearly bought it rather than sell it after confirm with the lower timeframes.
Lesson is, the more experience you have, the better you trade. Thus, backtesting and practicing is the answer to better performance.
