Stock Prices Tick History via Intrinio

Developer-friendly backtesting data for stocks

The Stock Prices Tick History data feed includes 100% volume data from the SIP.

We store the most recent 7 days in our database to power our Trades API. If you are caught up historically we recommend using this.

If you need to go further back in history, we recommend using the Replay Client (cold storage) instead of using the API to pull a large amount of data.
