| Field | Type | Description |
| - | - | - |
| `e` | STRING | `"ACCOUNT_UPDATE"` |
| `E` | LONG | Event time, Unix ms. |
| `L` | LONG | Login. |
| `x` | ENUM | `NEW`, `UPDATE` or `DELETE` on the underlying account record. `UPDATE` in practice. |

> **Equity, margin, free margin and margin level are NOT on this event.** They are not part of the
> underlying record this event is built from, and publishing a zero would be worse than publishing
> nothing. Read them from [`GET /v1/account`](/account/account-information.md), or derive
> equity as `b + cr + Σ(up + sw)` over the positions you are tracking from `POSITION_UPDATE`.
>
> If your risk logic depends on margin level, poll `GET /v1/account` at a rate you can afford and
> treat the derived figure as an estimate between polls.
