• Adjusting leverage settings

Prerequisites

• Open positions on Orderly
• Understanding of perpetual futures
• API key with read and trading scopes

Position Data Structure

interface Position {
  symbol: string; // e.g., "PERP_ETH_USDC"
  position_qty: number; // Positive = long, Negative = short
  average_open_price: number; // Entry price
  mark_price: number; // Current mark price
  unrealized_pnl: number; // Unrealized profit/loss
  unrealized_pnl_roi: number; // ROI percentage
  mmr: number; // Maintenance margin ratio
  imr: number; // Initial margin ratio
  notional: number; // Position value
  leverage: number; // Current leverage
  est_liq_price: number; // Estimated liquidation price
  cost_position: number; // Position cost
  settle_price: number; // Settlement price
  unsettled_pnl: number; // Unsettled PnL
}

Get Positions (REST API)

// Get all positions
GET /v1/positions

// Get position for specific symbol
GET /v1/position/{symbol}

{
  "success": true,
  "data": {
    "rows": [
      {
        "symbol": "PERP_ETH_USDC",
        "position_qty": 0.5,

React SDK: usePositionStream

Stream positions in real-time with automatic PnL updates:

import { usePositionStream } from '@orderly.network/hooks';

function PositionsTable() {
  const {
    rows,
    aggregated,
    totalUnrealizedROI,
    isLoading
  } = usePositionStream();

  if (isLoading) return <div>Loading positions...</div>;

  return (
    <div>
      <div className="summary">
        <h3>Total Unrealized PnL: {aggregated?.totalUnrealizedPnl?.toFixed(2)} USDC</h3>
        <p>ROI: {(totalUnrealizedROI * 100).toFixed(2)}%</p>
      </div>

      <table>
        <thead>
          <tr>
            <th>Symbol</th>
            <th>Size</th>
            <th>Entry Price</th>
            <th>Mark Price</th>
            <th>Unrealized PnL</th>
            <th>Leverage</th>
            <th>Liq. Price</th>
          </tr>
        </thead>
        <tbody>
          {rows.map((position) => (
            <tr key={position.symbol}>
              <td>{position.symbol}</td>
              <td className={position.position_qty > 0 ? 'long' : 'short'}>
                {position.position_qty > 0 ? '+' : ''}{position.position_qty}

              <td>{position.average_open_price.toFixed(2)}</td>
              <td>{position.mark_price.toFixed(2)}</td>
              <td className={position.unrealized_pnl >= 0 ? 'profit' : 'loss'}>
                {position.unrealized_pnl.toFixed(2)} USDC
              </td>
              <td>{position.leverage}x</td>
              <td>{position.liq_price.toFixed(2)}</td>
            </tr>
          ))}
        </tbody>
      </table>
    </div>
  );
}

Close Position

Partial Close

import { usePositionClose } from '@orderly.network/hooks';

function ClosePositionButton({ symbol, positionQty }: { symbol: string; positionQty: number }) {
  const { closePosition, isClosing } = usePositionClose();

  const handleClose = async (percentage: number) => {
    const quantity = Math.abs(positionQty) * (percentage / 100);
    await closePosition({
      symbol,
      qty: quantity,
      side: positionQty > 0 ? 'SELL' : 'BUY',
    });
  };

  return (
    <div>
      <button onClick={() => handleClose(25)} disabled={isClosing}>Close 25%</button>
      <button onClick={() => handleClose(50)} disabled={isClosing}>Close 50%</button>

Take-Profit / Stop-Loss Orders

TP/SL Order Types

Using useTPSLOrder Hook

import { useTPSLOrder } from '@orderly.network/hooks';

function TPSSettings({ position }: { position: Position }) {
  const [computed, { setValue, submit, validate, reset }] = useTPSLOrder(position);

  const handleSubmit = async () => {

      console.log('TP/SL order placed');
    } catch (error) {
      console.error('TP/SL failed:', error);
    }
  };

  return (
    <div className="tpsl-form">
      <h4>Take Profit</h4>

Cancel TP/SL Orders

// Cancel single algo order
DELETE /v1/algo/order?order_id={order_id}&symbol={symbol}

// Cancel all algo orders for symbol
DELETE /v1/algo/orders?symbol={symbol}

// React SDK
const [algoOrders, { cancelAlgoOrder }] = useAlgoOrderStream();
await cancelAlgoOrder(orderId);

Position History

GET /v1/position_history?symbol={symbol}&start={timestamp}&end={timestamp}

// Response includes closed positions with realized PnL

PnL Calculations

Unrealized PnL

// For LONG positions
unrealizedPnL = (markPrice - averageOpenPrice) * positionQty;

// For SHORT positions
unrealizedPnL = (averageOpenPrice - markPrice) * Math.abs(positionQty);

ROI

// Return on Investment
roi = unrealizedPnL / ((averageOpenPrice * Math.abs(positionQty)) / leverage);

Liquidation Price

// For LONG positions
liqPrice = averageOpenPrice * (1 - mmr - 1 / leverage);

// For SHORT positions
liqPrice = averageOpenPrice * (1 + mmr + 1 / leverage);

Margin vs Collateral: Understanding the Hierarchy

Orderly uses a multi-layer risk system. Here's how the pieces fit together:

Your Deposit
     ↓
[Collateral Factor] → Determines effective collateral value
     ↓
Effective Collateral (what you can actually use)
     ↓
[IMR/MMR] → Required margin per position
     ↓
Used Collateral (locked in positions)
     ↓
Free Collateral (available for new trades)

The Three Layers Explained

1. Collateral Factor (Token Level)

• Set per token by Orderly risk team
• Example: USDC = 1.0, USDT = 0.95
• Applied when you deposit: $1000 USDT × 0.95 = $950 effective collateral
• Where to find it: GET /v1/public/token

2. IMR/MMR (Position Level)

• IMR (Initial Margin Ratio): Minimum collateral needed to OPEN a position
• MMR (Maintenance Margin Ratio): Minimum collateral needed to KEEP a position open
• Determined by leverage: 10x leverage = 10% IMR, ~5% MMR
• Applied to position notional: $10,000 position × 10% IMR = $1,000 required
• Where to find it: Position object or symbol info

3. Account Margin Ratio (Account Level)

• margin_ratio = total_collateral / total_notional
• If this drops toward MMR, you're approaching liquidation
• Where to find it: GET /v1/client/holding

Calculation Example

Deposit: $10,000 USDC (collateral_factor = 1.0)
Effective Collateral: $10,000

Open Position: $50,000 ETH-PERP at 10x leverage
IMR Required: $50,000 × 10% = $5,000
MMR Required: $50,000 × 5% = $2,500

After opening:
- Used Collateral: $5,000
- Free Collateral: $5,000
- Margin Ratio: $10,000 / $50,000 = 20%

Liquidation happens when:
- Margin Ratio drops to MMR (5%)
- That means your collateral drops to $2,500
- Or position grows to $200,000 notional

Key Takeaway: You need sufficient effective collateral (after collateral factor) to meet IMR requirements (determined by leverage). The margin_ratio tells you how close you are to liquidation (determined by MMR).

Common Issues

"Position would exceed max leverage" error

• Current notional with new leverage exceeds limits
• Reduce position size or increase collateral

"Insufficient margin for TP/SL" error

• TP/SL orders require available margin
• Close some positions or add collateral

TP/SL not triggering

• Check if trigger_price is valid
• Verify the order is in NEW status
• Market may have gapped past trigger

Liquidation risk

• Monitor margin_ratio closely
• Set stop-losses early
• Watch funding rates for extended positions
