### Order fill status

The `fill status`

of an order indicates the proportion of the order that has been filled. It's expressed as a ratio comprised of a numerator and a denominator.

Orders containing ERC1155 tokens can be partially filled. The `fill_status`

field in the `order_updated`

event payload or in the `get_order(s)`

response will indicate the ratio of the order that is currently filled. If the order has not been filled at all, the `numerator`

and `denominator`

values of the `fill_status`

field will be `0`

. If the order has been fully filled, the `numerator`

and `denominator`

values will be equal.

Example #1 the below snipped would indicate that 50% of the order has been filled.

`"fill_status": {`

"numerator": "1",

"denominator": "2"

}

Example #2 the below snipped would indicate that 25% of the order has been filled.

`"fill_status": {`

"numerator": "1",

"denominator": "4"

}

Orders containing ERC721 tokens can only have a single asset and therefore only be fully filled so the numerator and denominator values in the `fill_status`

will be `1`

to indicate that the order has been fully filled.

Example #3 the below snipped would indicate that 100% of the order has been filled.

`"fill_status": {`

"numerator": "1",

"denominator": "1"

}
