If the trade doesn’t work study which point of your analysis faulted and sharpen that. Could it have been that your technical analysis was 150% accurate but you missed some big news? (I.e ceo stepping down)
Whichever it was correct it and get back in the game. Red days are going to HAPPEN, but so are BIG NUMBER GREEN DAYS 📈📈📈.
Remember, maintaining your risk threshold is nonnegotiable.
