On fetching historical data (one minute) for the symbol "HDFCGOLD-EQ" with token "19543" for the first of december 2023 (entire day), only 334 data points are observed. But in a trading day there are 375 minutes so 375 should have been observed. Does SmartAPI not give data for minutes in which there were no trades or something? Fetching the same data for HDFCSILVER-EQ gives even fewer data points (247). Can someone confirm?
