Leverage decisions should begin with liquidation distance. Coinbase?s perpetual-futures education page highlights two basic controls: set stop-loss orders and maintain a sufficient liquidation buffer. The point is simple but often ignored. Initial margin opens the position; maintenance margin keeps it alive; extra funds and smaller size create room for normal volatility.
Stops also need a trigger framework. Binance Futures explains that stop-loss and take-profit behavior depends on the trigger price relative to Last Price or Mark Price. Its guide notes that trigger timing can depend on mark-price precision and truncation rules. In practice, that means a trader who only watches the visible last-traded price may misunderstand when a futures stop can activate.
A cleaner pre-trade checklist has four numbers. First, define maximum account loss if the trade thesis fails. Second, calculate position size from that loss, not from the maximum leverage available. Third, place the stop far enough from the liquidation price that the exchange is not closing the position before your plan can work. Fourth, check whether the order uses mark price, last price or another trigger source.
This matters most during fast macro or crypto-specific moves. Funding spikes, thin order books and sudden wicks can make a narrow buffer disappear quickly. If a trader needs 20x leverage for the trade to look attractive, the setup may be too fragile. Lower leverage, partial entries and smaller contracts usually create more decision time than constantly adjusting a stop after the position is already stressed.
Risk notice: Perpetual futures are high-risk products. Stop orders and buffers cannot guarantee exit prices, and liquidation can occur before a trader manually reacts.
