Volume distribution
Based on live mainnet sampling (~15,000 events in 15 seconds). Ratios shift over time as market activity changes:
The stream is dominated by high-frequency market maker operations. Rarer action types (orders, transfers, governance) appear less frequently but carry high signal value.
All events include resolved asset names. 100% coverage across all 229 perps, 288 spot pairs, and all margin variants.
Formatted vs raw
22 action types have dedicated formatters that produce named JSON fields (e.g.,"side": "buy", "price": "67881.0"). The remaining 31 types pass through as raw JSON arrays. Raw events are still valid JSON, just with positional rather than named fields.
