Yesterday market had a substantial correction, so to test the current market state, I bought some shares of this. If the pnl remains positive, then the market is still uptrend.
Trade closed manually:
After I bought it, it kept showing losses, which meant that my assumption was probably wrong, so I decided to get out.
Comment:
Sometimes if I am not careful, I will fall into the trap of human nature, expecting 70 points to become 100 points instead of directly choosing the trend of 100 points.
