*Upgrade your terminal to the latest stable version for the best experience and support.

Equities Data

  • Full Trade Stream: Provides every trade reported on the Nasdaq Basic Feed with the last BBO quote at the time of trade.

  • Bulk Equity Snapshot: returns a real time last BBO quote or OHLC for every stock from the Nasdaq Basic Feed in 25ms.

  • Live Current Day History: By specifying the venue parameter, you can now retrieve real-time, current day historic data for equities.

  • Dividends: We now support historical dividend data.

Options Data

  • Trade Greeks Performance Boost: You can now specify the perf_boost=true parameter to read 1 second intervals for the underlying instead of tick-level quotes. This significantly improves the speed of historic trades greeks requests. 

  • Real-time Option Greeks: All equity option greeks snapshot endpoints use the real-time underlying price as a source.

  • Historic All Greeks: We now return 1st, 2nd, and 3rd order greeks in a single response for both trades and quotes.

  • List Contracts by Root: You can now list all contracts that were quoted or traded on a specific day for a specific symbol(s).

Bulk Historic Data Improvements: You can now request historic data for the entire underlying symbol by specifying exp=0. Below is a list of current exp=0 support. We have also optimized these exp=0 requests to perform less random disk operations than our old method. We have plans to expand this support to other requests like trade_quote and trade_greeks soon.

Other Cool Features

  • Stream Resubscription: Theta Terminal 1.6.3 or later will automatically resubscribe to all previous streams upon a reconnect to Theta Data. This makes weekend maintenances or unexpected disconnects much more graceful.

  • Verify Stream Requests: You can now verify if your WebSocket streaming requests were successful.

  • Start & End Time: You can now specify the start and end time you’d like to access tick level or intervals data on.

August Timeline 

  • Full 12 years of cached and v2 (anything that isn’t quotes) for OPRA options and UTP equities data.

  • New EOD reports that use 15:45 ET as the time of generation. A greeks report that uses this time will also follow.

  • Everything but tick-level OPRA NBBO will be moved to NVMe storage for faster retrieval.

  • Instantaneous availability of data from the previous day.

  • Snapshot support after our midnight reset, which would make snapshots work over the weekend.

  • Strike range for bulk historic data requests.

September Timeline

  • A sandbox week of history that anyone can access, regardless of subscription tier.

  • Bulk historic support for other requests.

  • Expansion of our presence in the EWR2 campus by over 300%.

  • Colocation in the NY4 campus.

  • New Website featuring API keys
