# Coinbase Derivatives: Predictions Downloads

Coinbase Derivatives: Predictions provides FIX dictionaries for download:

* [predictions-fix50sp2-xml-dictionaries-latest.zip](/derivatives-predictions/downloads/predictions-fix50sp2-xml-dictionaries-latest.zip)

### FIX Dictionaries

The FIX gateways speak FIX 5.0 SP2 over a FIXT 1.1 session layer, so each gateway has two QuickFIX-format XML dictionaries: a session (FIXT 1.1) dictionary and an application (FIX 5.0 SP2) dictionary. The session dictionaries differ slightly per gateway; use the matching pair.
