call_order_update_operation¶

This operation can be used to add collateral, cover, and adjust the margin call price for a particular user.

For prediction markets the collateral and debt must always be equal.

This operation will fail if it would trigger a margin call that couldn't be filled. If the margin call hits the call price limit then it will fail if the call price is above the settlement price.

Note: This operation can be used to force a market order using the collateral without requiring outside funds.
