1, the overnight trading cycle is large, the average amplitude of a single K line is large, and the stop loss is also large, which may not be affordable for small funds.

2. Under the same initial capital conditions, there are 1 time for overnight trading for 0-6 months, 1 time for opening positions and 1 time for closing positions. If both trading systems are stable and profitable and adopt the same initial position, it is obvious that the overall income of intraday trading will be higher than that of overnight trading.

3. Overnight trading can rely on natural big stop loss to curb the gap interval, and the sensitivity to gap is not so high.

4. Overnight trading is started in hours, and large-period entry and exit are insensitive to slip points and can accommodate large funds.
