The exchange rejected the order
The exchange rejected an order the combo sent. Trade retries automatically and leaves parameters and positions as they are. Follow the exchange’s message: add funds or adjust parameters.
What it means
The exchange rejected an order the combo sent, so nothing filled. The combo shows Ordering paused; retries automatically, and keeps trying until the order is accepted, the order conditions no longer hold, or you stop the combo. Parameters and the combo position stay as they are.
Why it happens
The exchange’s own message is the reference. It follows the status as Exchange error, and it is also in the Combo log. Common reasons are insufficient balance or margin, a risk limit, a size below the minimum order size, and a market that only allows reducing.
What to do
Insufficient balance or margin: add funds to that exchange account.
Other reasons: adjust the combo’s parameters according to the exchange’s message.
To stop the retries: choose Stop.
If the position on the exchange differs from the combo position, handle it in reconciliation. See Risk controls. For other reasons a combo doesn’t place orders, see Combo not trading.
