PS: Above the key position of the long-short transition is the bullish strength, the main long-short short position, below the long-short key position is the short-sell strength, the main short-short long, the support pressure level is the potential reversal point, the farther away it is (key position + Special K form) the higher the success rate of reversal! It's not that the big Yang line and the big Yin line directly break the position, and every key position of the contract transaction can be eaten!
