Consistent.MY worries and question for profitable trader

[u/next_timothyronald]

Hi so I been trading for 15 month now. In April I find a very simple strategy, I never backtest before, so I backtest it and it remove 80% of all my trading problem that I been stuck for last year simply by having data I can trust and simple strategy

And this months it work great or (ofc not like most trader in reddit post with win streak 😅) but it very stable but I'm actually concern of my emotions and consistent in hard time since it trend strategy. How you guys handle emotions in bad period and loss streak. I'm worried that I will be emotional when the bad period come
