Coinbase’s derivatives risk page explains that margin ratio tracks the buffer before liquidation and that 100% triggers liquidation and open-order cancellation. Kraken’s futures education page frames the near-liquidation moment as a choice among adding margin, partially closing, placing a stop above liquidation, or closing manually.
The important point is that liquidation risk should be managed before the warning zone. A trader who waits until the account is near forced liquidation no longer has a clean decision; fees, spreads, volatility and platform rules all become part of the outcome. A buffer is useful only when it is tied to an action plan.
A practical rule set can define three thresholds: reduce size when margin ratio reaches a warning level, stop adding risk when the buffer is thin, and close or hedge before the exchange liquidation engine controls the trade. Adding margin should require a still-valid thesis, not just a desire to avoid realizing a loss.
For futures traders, the best comparison is not which platform has the nicest liquidation screen. It is which workflow makes risk visible early enough to act: margin-ratio alerts, reduce-only exits, stop rules, collateral transfer speed and transparent liquidation fees.
