If you enter the market in 4 hours, you feel that you have already operated the band market at the daily level. Hold positions for 2-3 days or even longer,

If you are short-term in the day, you should look for opportunities on the 15 minute chart or the 5 minute chart. In this way, there can be 2-3 trading opportunities in one day to operate short-term intraday trading.

The above is just my own trading feelings, for reference only.
