# Account limits


Source: https://docs.stxapp.io/concepts/account-limits/

Every account carries limits set by STX, and users can set their own lower ones.
They are managed in the STX web and iOS apps; there is no REST endpoint for
them, and nothing here changes them.

Two of them affect trading through the API, and both surface as a rejected order
rather than as an error about limits:

| Limit | Effect |
| --- | --- |
| `ORDER_LIABILITY` | Caps your total outstanding order liability at any moment |
| `MAX_ORDER_LIABILITY_PER_ORDER` | Caps the liability on any single order |

Defaults are calibrated for casual participants, not market makers. If you are
sizing orders and seeing rejections you cannot otherwise explain, this is the
first thing to check. Contact STX support to have the ceilings raised.
