Perpetual futures look simple because they trade like a continuous contract, but the risk engine is different from spot trading. Bybit explains that funding rates are not fixed and update in real time before the funding timestamp. Coinbase’s perpetual-futures education also frames funding as a mechanism that helps keep perpetual prices aligned with spot markets. For traders, this means funding is a recurring position cost or credit, not a footnote.
Liquidation rules deserve the same attention. Kraken’s futures liquidation support page says liquidation can occur when account equity is no longer sufficient to support open futures positions, with the system monitoring portfolio equity in real time. Kraken’s perpetual futures information also warns that if account equity drops below maintenance margin, liquidation may be triggered automatically and fees can apply.
The practical takeaway is to plan around three numbers before opening a position: entry price, funding sensitivity and liquidation distance. A trade that looks attractive on direction can still be poor if funding is expensive, the liquidation level is too close, or cross-margin collateral exposes the rest of the account. Traders should choose isolated or cross margin deliberately, reduce leverage when volatility rises, and use stops as a planned exit rather than treating liquidation as a stop-loss substitute.
Risk notice: this article is for education only and is not investment advice. Perpetual futures and margin products can create losses larger than expected, especially around fast price moves, funding spikes, thin liquidity and automatic liquidation.
