Difference Between Mark Price and Last Price Stop-Loss Trigger on BYDFi (APP)

In the BYDFi App, traders can also set stop-loss orders with either Last Price Trigger or Mark Price Trigger. Each option works differently under volatile conditions.

🔹 Last Price Trigger (Default)

• Stop-loss is triggered based on the most recent trade price.
• Easier for traders to predict outcomes.

⚠️ Risk: Since liquidation uses the Mark Price, your stop-loss might not activate before liquidation occurs.

🔹 Mark Price Trigger

• Stop-loss is triggered by the Mark Price, reducing liquidation risk.
• Ensures positions are closed before liquidation is hit.

⚠️ Risk: Execution still depends on Last Price, so there can be slippage if the two prices differ.

How to Set Trigger Price Method on APP

1. Log in to the BYDFi App and open the Perpetual Contracts trading page.

2. Select the position you want to manage.

3. In the Stop Loss settings, choose either Last Price or Mark Price.

4. Enter your stop-loss price and save changes.

✅ On the App, choosing Mark Price can better protect against forced liquidation, while Last Price makes execution more predictable.
