In stock trading, what do the time-sharing data green and purple mean?

S = sell? The meaning of selling (taking the initials) is the number of transactions at that time!

B=buy (initial) means buy, that is, the number of transactions at that time!

B is active buying, not external selling: selling at the selling price is generally considered as active buying and bullish;

S is active selling, not internal selling: selling at the purchase price is generally considered as active selling and short selling.

The purple number is the number of transactions at this time point, the number of hands, and one hand = 100 shares.

I hope I can help you. If necessary, please adopt it!
