The host receives k-strings that continuously accumulate together, requiring a certain frequency of access to the exchange. The GetRecords interface, otherwise, may affect the continuity of the data. ======= Can you give an example of what k-string accumulation means?
The Little Dream- Call GetRecords once and the bottom layer gets the K-line data: [1, 2, 3, 4, 5] - Call GetRecords once and the bottom layer gets the K-line data: [2, 3, 4, 5, 6]. - Call GetRecords once, and the bottom layer gets the K-line data: [3, 4, 5, 6, 7]. The result is that the final GetRecords function returns to you: [1, 2, 3, 4, 5, 6, 7].
