Product roadmap

Currently, indices are indirectly supported through tradable index instruments on CME futures, ETFs, etc. and we don't provide the index values (non-tradable) themselves. This may be sourced from a feed like the Cboe Global Indices Feed or NYSE Global Index Feed.

The legacy live usage-based plans allowed users to access L2/L3 data. However L2/L3 were pulled from the Standard plan. One possibility to increase the value of the Standard plan is to offer limited access to L2/L3, perhaps gated by a quota on symbol subscriptions per account, etc.

Could we add support to make the result of DBNStore.to_df a Polars dataframe as well? Perhaps the function signature could just be overloaded with a to_polars: bool argument. Something like: In Python @overload def to_df(self, to_polars: Literal[False]) -> pd.DataFrame: ... @overload def to_df(self, to_polars: Literal[True]) -> pl.DataFrame: ... Or, maybe to_df is split into two different functions to_pandas and to_polars. Either way, it would be helpful to avoid having to do pl.from_pandas(store.to_df().reset_index(drop=False)). Plus, Polars can convert to pyarrow-Pandas zero-copy, but not the other way around.

Full depth of book feed for Cboe Futures Exchange (CFE). CFE contains volatility futures and corporate bond index futures, such as VIX futures (VX, VXM).

This client library makes all our historical and live features easier to integrate in C# on Windows, Linux, and Mac OS. C# is currently already supported through our HTTP API and Raw TCP protocol, which are both language-agnostic.

Make our historical and live APIs easier to integrate from Java.

Add trade reporting modifier flags, e.g. those found in CTS sale conditions here: https://www.nyse.com/publicdocs/ctaplan/notifications/trader-update/cts_output_spec.pdf Similar to: https://roadmap.databento.com/b/n0o5prm6/feature-ideas/include-opra-trade-conditions

Original request from Juan Linares: "Great product but please add dark mode." There are two separate parts to this: Dark mode for the portal and main website (databento.com, databento.com/portal) Dark mode for the docs We can consider this only after Q1 2025 since we're doing a major rebranding of our website which is expected to finish by early April 2025. The new colors will make it easier for us to implement a dark mode.

Currently, the cancel action type C is used for both actual order cancellations and trade-related deletions. This makes it hard to construct features based on order cancellations as they need to keep history of trades or fills and ignore cancellations that come after. To solve this, we'll be introducing a delete action type D to delete orders after a trade.

Several equities prop feeds provide market participant IDs (MPIDs). Currently, our normalized MBO format is lossy at the moment and fails to expose these MPIDs, and our only partial solution is to provide raw pcaps from which these can be extracted. This ticket will also partly facilitate this: https://roadmap.databento.com/roadmap/raw-data-via-api

Kalshi is a regulated exchange where you can trade on the outcome of real world events: https://kalshi.com/

Point-in-time mutual fund data, including mutual fund performance, expenses, and other related information such as equity holdings.

Currently any unresolved symbol results in the session ending and the connection being closed. The live API should have non-fatal errors for issues like an unsupported schema and symbols that fail to resolve. This is tracked internally as D-579

Would be great to have futures listed in TMX, particularly the equity and bond futures (SXF, CGB, CGF etc.)

Report by Stefan: client.symbology.resolve( dataset="GLBX.MDP3", symbols=['ES.v.0', 'ES.v.1'], stype_in="continuous", stype_out="instrument_id", start_date="2025-01-01", end_date="2025-06-01", ) returns something like: {'result': {'ES.v.0': [{'d0': '2025-01-01', 'd1': '2025-03-19', 's': '5002'}, {'d0': '2025-03-19', 'd1': '2025-06-01', 's': '4916'}], 'ES.v.1': [{'d0': '2025-01-01', 'd1': '2025-03-19', 's': '4916'}, {'d0': '2025-03-19', 'd1': '2025-03-23', 's': '5002'}, {'d0': '2025-03-23', 'd1': '2025-06-01', 's': '14160'}]}, 'symbols': ['ES.v.0', 'ES.v.1'], 'stype_in': 'continuous', 'stype_out': 'instrument_id', 'start_date': '2025-01-01', 'end_date': '2025-06-01', 'partial': [], 'not_found': [], 'message': 'OK', 'status': 0} Per issue report: "ES.v.0 rolls from contract 5002 to 4916 on the 19th, however ES.v.1 doesn't roll from 4916 to 14160 on the same day. Instead, it switches temporarily to the former front contract 5002. The logic naively just sorts every day by volume." It's likely this will need to be addressed introducing another roll rule rather than changing the behavior of existing roll rules, since we suspect this will glitch on symbols like SR3, ZQ, GC, which don't automatically have a monotonic decay in volume/OI the further out you go on expiration month. This roadmap ticket also tracks the implementation of time-to-expiry style roll rules, e.g. roll on T-1, ..., T-7 of expiration, similar to that found on other institutional data providers like Bloomberg.
