I make intraday short trades according to my trading system, and I don't think there's anything wrong with it.

Let me explain the logic behind this strategy.

The lower highs and lows on a smaller scale reduce, the trend line suppresses to 3198, I take partial profits, and the rest is for defense. If the trend line is broken, I will continue to look downward, and the defense for profit-taking is also coordinated.

Positions that profit from the moment they open either end up with zero profit or continuously flipping the account by catching the big moves.
