# Action Types Overview

> All 53 recognized action types on HyperLiquid

## Volume distribution

Based on live mainnet sampling (\~15,000 events in 15 seconds). Ratios shift over time as market activity changes:

| Action           | Share  | Description                                |
| ---------------- | ------ | ------------------------------------------ |
| `cancelByCloid`  | \~54%  | Cancel orders by client order ID           |
| `cancel`         | \~40%  | Cancel orders by order ID                  |
| `batchModify`    | \~4%   | Batch modify existing orders               |
| `scheduleCancel` | \<1%   | Schedule future cancellation               |
| `setReferrer`    | \<0.1% | Set referral code                          |
| All others       | \<0.1% | Orders, transfers, governance, HIP-4, etc. |

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.
