GetRecords custom cycle exception issue

Author: I know., Created: 2021-12-07 14:20:31, Updated:

Hi, I'm using exchange.GetRecords ((54*60); the custom cycle returns only 7 data when it gets a K-line record. I'm trying to find out why this is the case, but using PERIOD_M5 can return 300 items. Thank you.

I know.I want to ask, when does the k-line start to be used as the start time? For example, the synthetic K line of 54 minutes, what time is the opening time of the 54 minute K line?

Inventors quantify - small dreamsData for non-standard cycles are synthesized in small cycles, so the number is relatively small.

Inventors quantify - small dreamsThe exchange gives you a few hundred interfaces, your non-standard cycle can only synthesize in 1 minute, you count 54 in 1 minute to synthesize one, how much does it take to synthesize 10 interfaces, some exchanges get less than 500 interfaces at a time.

I know.I'm using analog disks, not backtesting, and with the support of massive data cycles, is it possible to synthesize smaller cycles, 55 minutes, is it possible to understand a cycle of 11 five-minute cycles?
