Actually, when it comes to speculative trading—especially short-term trading—being fickle and changing your mind is the norm, unless you’re a big swing trend trader who takes positions for several weeks or even months, with a sufficiently thick safety cushion.

However, it seems that not many people are able to understand and accept it.
The market has its own way of moving and won’t shift according to your will, so the only thing you can do is follow as closely as possible and trade in line with the trend.
