Hi @sudhanshu_mitkari
The Market Quote API has a limit of 500 stocks per call, while a single WebSocket connection supports up to 100 stocks.
Currently, there is no direct method to fetch live market data for more than 500 stocks simultaneously. However, our team is actively working on a new WebSocket release that will enable subscriptions to a larger number of instrument keys. You can find more details here: New Market Data WebSockets Discussion.
