I see that everyone wants to bottom fish...

Here's a small suggestion, just a small suggestion.

If you think waiting until 4 o'clock is too long and don’t want to wait,

then pay attention to the 12 o'clock closing situation, and use the lower edge of the k line at 12 o'clock as your stop loss. Wait for the first occurrence of a bullish engulfing candle (a bullish engulfing the bearish) before entering the market, and set the stop loss at 0.3-0.5% below the lower edge of the previous 4-hour k line. If it gets swept, just let it go.

If you don’t want to wait for this either, then at least wait for the 1-hour level. After the bullish engulfing is completed, the stop loss should still be based on the lower edge of the previous 1-hour k line.

However, the smaller the time frame, the higher the probability of being swept away.

Everyone is waiting for the ETF to continue buying, but what if the ETF doesn’t buy? What if it reduces its holdings?

You can't have a path dependence mentality.

The above is just a small suggestion; if you miss out or whatever, just don’t blame me.
