So when I call this function again, all I have to do is call the k-string one hour before and the k-string 20 hours before, and then I'm thinking, what is my k-string? records = exchange.GetRecords ((PERIOD_H1)) is the name of the After records[0] is the 2000th data item, the most accessed 2000 items written on the development documentation
The Little DreamWell, this 2000 says the upper limit. Specifically, every time you call exchange.GetRecords to the exchange server requesting a K-bar, the exchange will return to you the number of root bars of data, depending on the exchange, each exchange may have a different number of returns. Specific records[0] are data for what time, how many bars are there from now, this is uncertain.
