Choosing a mode means choosing your risk boundary
Cross margin backs every position with the whole futures balance, absorbing noise better yet risking the full account; isolated stakes only the assigned margin and stops there. The question is not which is better but how much one trade is allowed to cost you.
What to prepare before you start
These five things cover almost every delay people run into: Your futures balance and the share you plan to commit.
The maximum loss this single trade may take. Whether you hold several positions in the same direction.
Awareness that switching modes changes existing liquidation prices.
A decision rule for picking a mode
Answer these five questions and the answer appears:
Is this a clean short-term idea
Then isolated keeps it tidy.
Do you need the whole account to absorb wicks
Then cross is smoother.
Do you want a hard cap on loss
Isolated provides it by design.
Are you holding offsetting positions
Cross reflects net exposure best. Preview the new liquidation price before switching and accept it first.
Fees, limits and processing times
Numbers change from time to time, always confirm on the official fee page before you commit size: Perpetual contracts track spot through funding payments; dated contracts settle on expiry.
Cross, isolated and portfolio margin modes change how your balance supports positions - the liquidation price follows from the mode you choose. Withdrawals require the fund password plus a two-factor code, and limits scale with your verification level.
Arrival time depends on the network; newly added addresses may need additional review before the first transfer is allowed. Spot, margin, perpetual and dated futures, plus options, sit at the core of the platform.
Strategy tools such as grid and DCA bots, copy trading, OKX Wallet with its DEX aggregator, and Earn products extend well beyond simple trading.
The OKX-specific part
Beyond cross and isolated, OKX offers portfolio margin for multi-currency hedgers. Switch from the position or settings page and note the recalculated liquidation price.
Frequently asked questions
Can I switch modes mid-trade
Usually yes, though it changes margin usage and liquidation price, so review the estimate first.
Is isolated always safer
It caps one position, but smaller buffers mean that position liquidates sooner.
Why does one bad position hurt others in cross mode
They share one balance, so any loss drains the common collateral.

Do not switch modes during violent moves; estimates become unreliable. Always set stops anyway - margin mode is not a substitute for risk control.
