What is a Liquidation Price?
When you trade with leverage, you borrow capital from the exchange. If the market moves against you far enough to consume your margin, the exchange forcibly closes your position at the liquidation price. You lose your entire margin deposit for that trade.
Understanding your liquidation price before entering a trade is one of the most basic — and most ignored — rules of leveraged trading.
The Liquidation Price Formula (Isolated Margin)
Long: Liq Price = Entry × Leverage / (Leverage + 1 − MMR × Leverage)
Short: Liq Price = Entry × Leverage / (Leverage − 1 + MMR × Leverage)
MMR = Maintenance Margin Rate (typically 0.4–0.5%)Example: BTC long at $65,000 with 20× leverage and 0.5% MMR:
Liq Price = 65,000 × 20 / (20 + 1 − 0.005 × 20)
= 1,300,000 / 20.9
≈ $62,200 (only 4.3% below entry)How to Protect Your Position
Never let the exchange liquidate you — always set a stop-loss above your liquidation price. The standard practice is to set it at 40–60% of the distance to liquidation. This way, you control the exit and keep some capital instead of losing everything.
Also consider: the higher the leverage, the closer your liquidation price is to your entry. At 50× leverage, a 2% adverse move is enough to wipe your position.
