something like this might be applied in the trading system to always be in a hurry to close a position, even if fear changes direction plus minus should be left using the SL, so there is a backup plan, because the SL and TP are very import and you don't have to trade primarily based on feelings your personal. I would like to question whether you really opened that position by utilizing the signal from the indicator, mainly based on the whole strategy or you recently felt that you had to open it. that will be the main reason you might be afraid concerns arise not when you are in profit but when you lose. But if you are sure of the trade, you may not need to be afraid. You will fail many times but you can create many benefits if you really trade with a strong strategy not with feelings.
