Based on today's random review, I realize that sometimes I was too impatient with my trades.

After judging that the timing was right and entering on a small timeframe, I felt that the trend was starting.
At this point, I wanted to quickly switch back to the larger timeframe.
Then I ignored the small timeframe,
which in many cases had already reached the peak of the wave,
or even started to show signs of divergence,
but I didn't switch back to the small timeframe in time to reassess.
This is what caused some issues,
and is often the reason for profit retracements and losses.
