Needs API to get historical data of multiple instruments

Developer API

Hi

I am creating Stock screener which will needed API to get Historical data of multiple stocks. As there are 6000+ stocks if I go one by one then API will hit Rate limit. Is there any API that can provide historical data for multiple strikes?

Currently, there is no API available for retrieving historical data for multiple stocks.

Please introduce the option for getting historical data of multiple stocks in one API call.

Thank you for your feedback. Historical APIs are cached, and most of the time, responses are served directly from the cache, which enhances performance. Currently, we are not planning to introduce functionality for retrieving data for multiple stocks in the near future.

You can provide API which accepts multiple stocks and you can internally get cached data for specified periods which will reduce API calls.

Thank you for the suggestion. We will forward it to the appropriate team.

Or you could simply increase the 30-minute rate limit on API calls from 2,000 to something like 5,000. The need for multiple API calls usually arises when someone is trying to build a custom stock screener that requires historical data for the entire universe of stocks, which most traders would want to do at some point. A limit of 2,000 API calls per 30 minutes is too restrictive for such a use case. You can keep the per second and per minute rate limits unchanged or even introduce a new 5 minute rate limit to avoid any misuse of API calls. But having to wait 30 minutes to get the data for the rest of the instruments is not very unfavourable.

I am also facing a lot of issues with rate limits. It will be great if you can increase the API rate limits for the calls which are not related to orders.
