Just to clarify. To confirm that this is not an issue in my code I downloaded Binance Postman collection and created simple request with symbol == DOTBTC and other parameters unspecified. And I created one test in postman that verifies if count of returned items is 91 (correct count). And I can run it subsequently getting pass or fail on that test randomly. I don’t see any correlation with how often I send requests. So this is not about hitting limits.
