If a particular trade isn't going well for you, you just have to understand that loss is a part of the game and move on to other trade with a fresh mindset and not with the mindset of wanting to make back your losses because that could affect your decision making and make you make the wrong moves that'll most likely cost you more funds.
I agree because recovering losses with other trades is easier than struggling with open trade without stoploss. Personally I have experienced trading without stoploss and I kept my open trade for weeks but market never bounced back; instead of booking a small loss at stoploss, I lost almost all my capital. Accepting losses and getting back to fresh mindset are the most important things every trader must get practice to. Because, these are the things will help you to recover your losses quickly rather than struggling in the wrong direction of market.
I learned these things after multiple such bitter experience because I did not have this community when I was entering into trading; if this community was with me then I wouldn't have lost most of my capital.
