Hi @sangita_al
Apologies for delayed response.
Both Websocket streaming and getLTPdata API are efficient and functional.
GetLTPdata API can help retrieve LTP quotes for one or more instruments which presents LTP, OHLC values and so. While Websocket streaming can provide more market value as such LTP, 52 week high/low, Best five values and so
According to the business requirement, the functionalities can be implemented.
