Can be equated with stocks. Before the stock is pulled up, the washing step is a necessary step after the stock is pulled up. There are three situations: the first is sharp fluctuation, the second is horizontal consolidation with small shrinkage, and the third is continuous downward revision, but it does not exceed the previous low. The stock or futures contract that has gone through the washing process will definitely hit a new high, otherwise it is not called washing, but shipping. I hope I can help you.
