Once you've reached your target, continuing to trade can turn a good day into a bad one. The temptation is usually, "I'm already profitable, so I'll take one more." That extra trade can completely change the day's result. Do you stop when you hit your target?
once you hit your target you proper just gotta shut the screens down and call it a day, that classic itch of thinking "just one more trade" is literally what always ends up rinsing the whole session's graft right back down the drain. used to do it all the time myself back in the day, spaffing a decent day's profit up the wall just because i couldn't keep my hands off the mouse. knowing when to walk away takes way more discipline than actually staring at the charts all shift, taking the win and logging off is the only way to stay in the game long-term.
