Misguided buy call gone right

So I have seen an amazing buy setup. I drew my price channel and when I drew my fibs. The long red bearish candle closed on top of my 0.5 on my fibs. I got in for a buy. The next candle opened to the downside and dropped, the Market structure was broken while I was in, this is the first time I've really dealt with drawdown. It broke out of my channel and it retests on my .764 so when it starts to come up I notified my team and for myself, I got out at -5 pips due do not trust myself. Over time as you see this call still hit TP right after I got out the trade. I watched it happen.

Note to myself, Price channel and fibs are confluences if one isn't solid respect the other one, there's no reason I should have got out this trade
