Question - Is index/stock price updates in Instruments master in intraday, right now I am calling api once in morning, but as Index price goes up and down, I want to calculate ATM / OTM based on current price.

The file for the instrument is a beginning-of-day (BOD) file that is refreshed each morning. Prices within the instrument are not updated during the day. To access the data, you can utilize the intraday cancel API or a websocket.

For API details, please refer to the following links:
