My current conclusion is pretty cowardly: I can't hold spot positions, and my futures keep getting liquidated. To be honest, it's not that I can't read the charts, but that my position sizes are too "serious." When emotions kick in, I end up destroying my plan. First, I should set a hard limit on each loss (accept it when it hits), keep my position size small enough for me to sleep peacefully, and leave the rest to ranges and time; otherwise, every candlestick looks like an ECG alarm.

Recently, there's been talk about data tools and label systems on the chain being laggy. I also have some faith in that: it looks very advanced, but in actual volatility, it might just be a "rearview mirror." So now I prefer to trust my few simple rules: set a range first, then divide into batches, don't add to a losing position, and don't change the script at the last minute even if I win... Anyway, what I fear most is my own careless hands.
