I am looking to fetch real-time pre-market data. Could you please advise on the suitable API for this?
Can WebSocket be used for real-time pre-market data? As per the documentation, only 100 instrument keys can be included in a single WebSocket request. Is it possible to create multiple WebSocket connections to track additional instrument keys?
2. Real-Time Data for Market Quotes and Intraday Candles
Are the Market Quote APIs and Intraday Candlestick Data APIs providing real-time data?
If there is a delay, could you specify the approximate delay for these data feeds?
3. Fetching Indices and Listed Companies
How can I retrieve a list of indices along with their constituent companies?
Is there any API available specifically for fetching indices and their components?
The WebSocket provides pre-market data, allowing you to utilize it for fetching such information. Additionally, you can establish up to three WebSocket connections to monitor extra instrument keys.
The Market Quote and Intraday Candlestick APIs provide real-time data; however, as REST calls, they typically have higher latency compared to WebSocket connections. Additionally, please be mindful of the rate limit rules associated with these APIs when using them.
As of now we do not have such an API. But your request is send to the concerned team.
