Which are the best brokers for market data feeds?
I am considering Fyers and Angel One for real-time market data. Both provide WebSocket APIs for subscribing to live prices, but I'd like to know the views of people who have actually used them.
How do they compare in terms of:
- Reliability and stability of the WebSocket feed
- Quality of API/technical support
- Ease of integration
- Subscription limits and how well they handle a large number of instruments
I am looking to stream data for 10,000+ instruments at a time, so the subscription limits and reliability at that scale are particularly important to me.
If there are other brokers that you think are better for market data feeds, do suggest.
