This is because of the way it works. So when a user requests for 3minute candles, we fetch 1minute candles in the backend and group by 3 to make it 3minutes candle.
So 1:27 will be 3 minutes -> which will have 1:27, 1:28, 1:29 Since the request is capped to 1:30 for the request with to date till 01:30, the last candle is only one
In case of request where to param is till 1:36, 130 will be 3 minutes -> which will have 1:30, 1:31: 1:32
So 1:27 will be 3 minutes -> which will have 1:27, 1:28, 1:29
