# Order lifecycle

> How order statuses changes during an order's lifetime.

An order has three statuses.

  P["<b>PENDING</b>"]
  A["<b>ACTIVE</b>"]
  I["<b>INACTIVE</b>"]
  P --> A --> I
  P -->|may skip ACTIVE entirely| I
```

| Status     | Means                                                                           |
| ---------- | ------------------------------------------------------------------------------- |
| `PENDING`  | Accepted and published to the matching engine. **Not live, not yet matchable.** |
| `ACTIVE`   | Resting on the book, in whole or in part.                                       |
| `INACTIVE` | No longer resting. `inactiveReason` says why.                                   |

<Warning>
  **`FILLED` is an `inactiveReason`, not a status.** A fully filled order is `status: "INACTIVE"`
  with `inactiveReason: "FILLED"`. A partial fill whose remainder falls below the minimum resting size
  (`limits.minRestingOrderSizeBaseUnits`) is also reported as `FILLED` — the engine discards the dust
  remainder rather than resting it.
</Warning>

IOC or FOK orders ("market orders") **skip `ACTIVE` entirely**. Both go from `PENDING` straight to `INACTIVE`. The order never rests, so it is never `ACTIVE`.

## The `inactiveReason` values

An order becomes `INACTIVE` if it is filled or cancelled. `inactiveReason` tells you which condition applied.

| `inactiveReason`       | Fires when                                                                                                                                                                                         |
| ---------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `FILLED`               | Fully matched, or a partial fill left a remainder below the minimum resting size (`limits.minRestingOrderSizeBaseUnits`), which is discarded.                                                      |
| `USER_REQUESTED`       | You cancelled it.                                                                                                                                                                                  |
| `EXPIRED`              | The order's `expiry` passed.                                                                                                                                                                       |
| `NO_LIQUIDITY`         | An IOC found no compatible liquidity, or an FOK could not fill completely.                                                                                                                         |
| `INSUFFICIENT_BALANCE` | A balance check failed at match time — on **either** the maker or the taker side.                                                                                                                  |
| `EVENT_LIFECYCLE`      | The fixture moved into a [state that sweeps resting orders](/api-reference/fixture-statuses#which-statuses-sweep-your-resting-orders) — in progress, finished, or cancelled. **Includes kickoff.** |
| `MARKET_HALTED`        | An operator explicitly halted the market.                                                                                                                                                          |
| `HEARTBEAT_TIMEOUT`    | Your [heartbeat](/developers/heartbeat) lapsed. Sweeps **every** open order on your account.                                                                                                       |
| `SYSTEM`               | The exchange cancelled the order. Covers several distinct internal causes.                                                                                                                         |
