Once the crossing happened, it will not repaint: ( the crossing: the white dot line cross the white solid line)

1. If there is a crossing at the open time of the higher timeframe, the crossing will not repaint.

2. If there is no corssing at the open time of the higher timeframe, there will not cross for the whole period of the higher timeframe.

In conclusion, the crossing only happens at the point of the open time of the higher timeframe.

1.如果在大级别的时间框架开盘时刻发生了交叉，则加仓不会消失重回。

2.如果在那个时刻没有发生交叉，则整个大级别的时间周期内都不会发生。

总而言之，交叉只出现在大级别周期开盘的那一刻。
