Maybe we should just be neutral without being too optimistic or pessimistic.
No person can be neutral in trading. It is either you are buying or you are selling. You buy when you are optimistic and you sell when you become pessimistic. All that depends on how price is moving and no where can price remain neutral. Staying neutral means that we believe price is not moving in any direction at all, and that will be wrong conclusion. Am optimistic.
This is not the reality of trading, you shouldn't trade at all if you feel too deeply about your losses/profits. The more you overthink the trade, the more problems start to appear during trade, the struggle becomes real if you can not decide which side you should choose. It is a simple zero-sum game, make your trading plan, conclude money management rules and apply technical analysis before deciding which side you gonna trade.
