Manual Close
Full Close
Click Close on any open position to exit entirely at the current bid (longs) or ask (shorts). Your collateral plus or minus PnL is returned to your wallet. The $0.10 oracle fee charged at open is refunded on a successful full close.Partial Close
Close a portion of your position while keeping the rest open. Set the dollar amount or percentage in the close dialog. Each partial close incurs a $0.10 oracle fee. The remaining position must still meet the pair’s minimum trade size.Automated Close: TP and SL
Take-profit and stop-loss orders close your position automatically when the market reaches your specified level. Both are set and managed from the Positions panel (see Managing Positions).- Take-Profit (TP): Triggers when price moves in your favor. Executes as a limit close at your target price.
- Stop-Loss (SL): Triggers when mid-price crosses your level. Executes as a market close at the bid/ask.
Liquidation
Liquidation is an automatic close triggered when your collateral falls below the liquidation threshold. There is no margin call. Keeper bots (Gelato Functions) execute liquidations onchain; the protocol pays the gas fee. After liquidation, remaining collateral is retained by the protocol as part of settlement. You do not receive any remaining collateral. See Vault Overview for how settlement flows reconcile onchain and offchain. See Liquidation for thresholds, formulas, and how to avoid it.Collateral After Close
| Outcome | What Happens |
|---|---|
| Positive PnL | Initial collateral + profits returned to your wallet. |
| Negative PnL | Initial collateral minus losses returned to your wallet. Losses retained by the protocol as part of settlement. |
| Liquidation | All remaining collateral retained by the protocol as part of settlement. Nothing returned. |
