Positions

Positions represent your active exposure in markets on the Nexus Exchange. Each position maintains a live state in the exchange's risk engine, tracking your entry price, size, collateral usage, funding, fees, and real-time profit and loss.

Positions update every block, giving near-instant feedback on risk, margin, and liquidation thresholds.

Open positions

Your open-positions view shows continuously updated metrics from the real-time risk engine:

• Unrealized PnL — shown in both USDX value and percentage
• Position Size — total notional exposure (long or short)
• Average Entry Price — volume-weighted entry across fills
• Margin Usage — collateral allocated to maintain the position
• Liquidation Price — the estimated price at which the risk engine liquidates your position
• Funding Payments — funding paid or received since opening

All calculations follow the deterministic margin and funding rules enforced inside the exchange engine.

Modifying positions

Active positions are managed through several methods to adjust exposure or exit trades. Updates are applied atomically by the matching engine.

• Adjusting Position Size

  • You can increase or decrease your position size via market or limit orders using the standard trading modal.
  • Orders in the opposite direction exceeding your current position size will automatically "flip" your positions.

    • For example, if you have 1 BTC active long and place a market sell for 2 BTC, you'll end up with 1 BTC active short.
• Closing Positions

  • Exit a position partially or in full from the Positions tab.
  • Closing executes a market or limit order on the opposite side and immediately realizes PnL after the fill.
• Position History

  • Track and review trading activity with transparent historical data through the Position History tab.
