Xiaolong has整理了几句相对实用的交易顺口溜，大家可以记一记：
Morning big drop can increase positions, morning surge should reduce positions
Continuous small rise will lead to a big rise
Continuous big rise should exit
Downward sideways will lead to a small rise
Upward sideways will continue to rise
Small drop with the trend indicates a big drop ahead
Sharp drop with no volume is intimidation
Slow drop with volume means to hold your position
