usePositions

import { usePositions } from "@0xmonaco/react";

const {
  listPositions,
  getPosition,
  getPositionRisk,
  closePosition,
  batchCloseAllPositions,
  attachPositionTpSl,
  listPositionHistory,
} = usePositions();

The hook returns the same surface as sdk.positions. Each method is the same async function, ready to call from components or effects. There’s no state, subscriptions, or auto-refresh built in — wrap calls in your own useEffect / SWR / React Query as suits your app. For end-to-end flow and UI patterns, see Positions.

(params?: ListPositionsParams) => Promise<ListPositionsResponse>

Paginated list of positions.Parameters:

params?:
- marginAccountId?: string
- tradingPairId?: string
- status?: "OPEN" | "CLOSED" | "LIQUIDATING"
- page?: number
- pageSize?: number

Returns: { positions: Position[]; total: number; page: number; pageSize: number }Example — positions panel:

function PositionsPanel({ marginAccountId }: { marginAccountId: string }) {
  const { listPositions } = usePositions();
  const [positions, setPositions] = useState<Position[]>([]);

  useEffect(() => {
    let cancelled = false;
    (async () => {
      const result = await listPositions({
        marginAccountId: marginAccountId,
        status: "OPEN",
      });
      if (!cancelled) setPositions(result.positions);
    })();
    return () => { cancelled = true; };
  }, [marginAccountId, listPositions]);

  return (
    <ul>
      {positions.map((p) => (
        <li key={p.positionId}>
          {p.side} {p.size} @ {p.entryPrice} — PnL {p.unrealizedPnl}
        </li>
      ))}
    </ul>
  );
}

(positionId: string) => Promise<Position>

Full snapshot of a single position. Includes side, size, entry/mark/liquidation prices, isolated margin, leverage, and PnL. See Position type.

(positionId: string) => Promise<PositionRisk>

Volatile risk fields (mark price, liquidation price, margin ratio, unrealized PnL). Cheaper than getPosition for live displays.Example — live liquidation distance:

function LiquidationBar({ positionId }: { positionId: string }) {
  const { getPositionRisk } = usePositions();
  const [distance, setDistance] = useState<number | null>(null);

  useEffect(() => {
    const tick = async () => {
      const risk = await getPositionRisk(positionId);
      const mark = parseFloat(risk.markPrice);
      const liq = parseFloat(risk.liquidationPrice);
      setDistance(mark > 0 ? (mark - liq) / mark : null);
    };
    tick();
    const id = setInterval(tick, 2000);
    return () => clearInterval(id);
  }, [positionId, getPositionRisk]);

  if (distance == null) return null;
  return <div>Liquidation distance: {(distance * 100).toFixed(2)}%</div>;
}

(params?: ListPositionHistoryParams) => Promise<ListPositionHistoryResponse>

Lifecycle events for one position or all positions in scope.Parameters:

params?:
- positionId?: string
- marginAccountId?: string
- tradingPairId?: string
- page?: number
- pageSize?: number

Modify

addPositionMargin and reducePositionMargin were removed from this hook. Adjust a position’s margin through the margin-account SDK surface — every leg moves collateral between a risk bucket and the parent margin account, never to or from the spot wallet:

transferCollateralToRiskBucket is the direct addPositionMargin replacement: by default it commits the amount to the open position’s stored margin (leverage drops and stays down); pass applyToPositionMargin: false to fund the bucket with spendable free collateral instead. The pair-scoped transferCollateralToMarginAccount is deprecated and matches the default.
transferCollateralFromMarginAccount (with tradingPairId) releases collateral back to the parent.

(positionId, request) => Promise<AttachPositionTpSlResponse>

Attach take-profit and/or stop-loss conditional orders to the position. At least one leg is required. Pass oco: true to cancel the sibling once one leg triggers (requires both legs).Parameters:

positionId: string
request:
- takeProfit?: TpSlLeg
- stopLoss?: TpSlLeg
- trailingStop?: TrailingStopLeg — { trailBps, activationPrice?, closePosition?, quantity?, slippageToleranceBps?, expiresAt? }; one per position, never part of oco. See Trailing Stop
- oco?: boolean — cancel the sibling leg after one triggers; requires both fixed legs

TpSlLeg:

{ triggerPrice, orderType: "MARKET" | "LIMIT", limitPrice?, closePosition?, quantity?, timeInForce?, slippageToleranceBps?, expiresAt? }

. Set closePosition: true to resolve the full live position size on trigger (omit quantity). See Order Management.Example — TP/SL modal submit:

const { attachPositionTpSl } = usePositions();

async function onSubmit(values: { tp: string; sl: string }) {
  await attachPositionTpSl(positionId, {
    takeProfit: { triggerPrice: values.tp, orderType: "MARKET", closePosition: true },
    stopLoss: { triggerPrice: values.sl, orderType: "MARKET", closePosition: true },
    oco: true,
  });
}

Close

(positionId, request) => Promise<ClosePositionResponse>

Submit a closing order. Position transitions to CLOSED only after the closing order fills.Parameters:

positionId: string
request:
- closeType: "MARKET" | "LIMIT" | "IOC"
- limitPrice?: string — required for LIMIT and IOC, forbidden only for MARKET
- quantity?: string — defaults to full position size
- slippageToleranceBps?: number — for MARKET / IOC

Example — partial market close:

const { closePosition } = usePositions();

await closePosition(positionId, {
  closeType: "MARKET",
  quantity: "0.5",
});

(request?: BatchCloseAllRequest) => Promise<BatchCloseAllResponse>

Submit a MARKET reduce-only close for every open position owned by the caller — a one-call “panic close”. Best-effort and partial: each position closes independently, and per-position failures are reported in results instead of aborting the batch. See BatchCloseAllResponse type.Parameters:

request?:
- tradingPairId?: string — limit the close to one trading pair; if omitted, all open positions are closed
- slippageToleranceBps?: number — applied to each MARKET close

Example — close-all button:

const { batchCloseAllPositions } = usePositions();

async function onCloseAll() {
  const { totalClosed, totalFailed } = await batchCloseAllPositions();
  if (totalFailed > 0) {
    toast.warn(`${totalClosed} closing, ${totalFailed} failed`);
  }
}

Subscribing to lifecycle events

usePositions doesn’t ship a built-in subscription. For live updates of conditional-order lifecycle (TP/SL state changes), use sdk.ws.conditionalOrders — see the WebSocket reference. For order-fill confirmations after a closePosition or attached-TP/SL trigger, subscribe to sdk.ws.userOrders.
