Place an IOC market order. It executes as an IOC limit at a worst-acceptable price mirrored around the oracle by side — BUY caps ABOVE the oracle, SELL below — at slippageBps distance (default 500 = 5%). Fills happen at book prices; the cap only limits how deep the sweep goes. reduceOnly closes an existing position. Returns confirmation with the REAL outcome verified via the indexer (filled / partially_filled / unfilled / pending): broadcast code: 0 only means the tx was accepted — an IOC order cancels UNFILLED when the book is entirely beyond the slippage cap (thin/spread market). Always report from confirmation.outcome, not code; if unfilled or partially_filled, retry with a larger slippageBps to sweep deeper; if pending, the indexer is lagging — wait a few seconds and re-check before concluding.

|---|---|---|---|
| market | string | yes | Market ticker, e.g. BTC-USD |
| side | string | yes | |
| size | number | yes | Size in base units |
| slippageBps | number | no | Max slippage vs oracle, in bps (default 500). BUY bounds above the oracle, SELL below; raise to sweep a thin book. |
| reduceOnly | boolean | no | |
| clientId | integer | no | |
