Does OKX factor the liquidation fee into the trigger?

Yes. OKX adds the taker fee rate directly to the maintenance margin rate in the denominator of the margin ratio formula. That shifts the liquidation trigger slightly closer to entry price.

What determines the maximum leverage on OKX?

Position notional (margin × leverage). OKX uses position tiers: the larger the position, the lower the allowed leverage and the higher the maintenance margin rate.

Very large positions get liquidated in steps on OKX (partial liquidation).

Auto-deleveraging (ADL) can close a position in extreme cases regardless of the liquidation price.

What sets OKX apart from other exchanges

OKX is one of the exchanges that adds a liquidation fee (the taker fee rate) directly to the maintenance margin rate before checking the 100% trigger threshold: Denominator = Position × Mark Price × (Tier MMR + Fee Rate). The result sits slightly closer to entry price than a pure MMR formula.

OKX also tiers its maintenance margin rate by position size (notional = margin × leverage). The calculator above automatically warns you if your desired leverage isn't even available for your position size.
