Propr Beta: Switch to mark.updated Feed
Summary
Propr announces a migration to the mark.updated feed to deliver live markPrice and unrealizedPnl with lower bandwidth and fewer messages. Action required: switch from position.updated to mark.updated, wire up the pure functions from the Integrations tab in TS or Python, and consult the docs. Changes are live in Beta and will be pushed to production next Monday.
Why
Lower bandwidth, fewer messages, and live values that update as smoothly as your mark feed instead of being gated by how often we push. It also aligns us with the mark-price-stream pattern builders already know from Binance/Hyperliquid-style feeds.
Action required
- If you relied on position.updated carrying live markPrice / unrealizedPnl every tick , witch to the mark.updated feed + the provided derivation functions.
- Wire up the pure functions from the Integrations tab (copy-paste, TS or Python).
- Full reference, the 15 event handlers, and a complete async Python client with reconnect logic are in the docs.
