Crypto Futures Liquidation: What Every Algo Trader Must Know

Liquidation is the number one account killer in crypto futures algo trading. Unlike spot trading where you can just hold, a futures position with insufficient margin gets forcefully closed by the exchange at the worst possible time.

How Liquidation Works

On Delta Exchange and similar platforms, your position is liquidated when your margin falls below the maintenance margin requirement. The exchange's insurance fund and auto-deleveraging system kick in to settle the loss.

Calculating Your Liquidation Price

For a long position: Liquidation Price = Entry Price × (1 - 1/Leverage + Maintenance Margin Rate). Always calculate this before a trade and ensure your stop-loss is triggered well before this level.

Insurance Funds

Delta Exchange maintains an insurance fund to cover losses from liquidated positions that go bankrupt. When the fund is depleted, the exchange uses auto-deleveraging (ADL) to forcibly close profitable positions. Understanding this is critical for any delta exchange api trading bot running large leveraged positions.

Building Liquidation-Aware Bots

Your crypto trading bot should query your current liquidation price on every tick and halt trading automatically if price comes within 5% of it.
