How does Master Boyi (Futures) shout the highest price and lowest price of the previous day in a 5-minute cycle? Kneel down! ! !
I feel that I need to call the highest price and lowest price of the previous day, whether it is five minutes data or daily data, so I don't have to bother. I just need to call the K-line through the system, so that the data of a few days ago will come out. You try. Master Boyi's K-line is not without a five-minute K-line, or you can use culture.
