How to know if something is wrong with you while Trading?

If you trade for the whole day, trying to grab each and every opportunity and every move up and down, you will definitely lose at the end of the day.

If you trade for the first two hours and still lose, then there is something seriously wrong with your strategy.

If you wait for opportunities but could not pull the trigger when they come and then buy the fomo, then you need to work on your psychology.
