Leverage and Margin: Choosing Leverage, Cross vs Isolated, Liquidation Price and Holding Costs

Futures leverage and margin: choosing leverage, cross vs isolated margin, liquidation price, funding rates and fees. Five guides covering a position's risks and costs.

Leverage does not create risk on its own; oversized positions do. With the same 100 USDT of margin, whether you use 5x or 50x, what decides the loss is notional size and stop distance. Bit LangLang's settled trades average 13.4x leverage. This hub explains how leverage, margin mode, liquidation price and holding costs fit together.

What this hub covers

Many traders treat the leverage number as the risk itself, so they either avoid leverage entirely or use high leverage without knowing where liquidation sits. These five guides start from position sizing: choose leverage, choose a margin mode, calculate the liquidation price, then add funding and fees to the cost.

Suggested reading order

Read how to choose leverage first and learn the formula notional size = loss budget ÷ stop distance. Then read cross vs isolated margin to see whether the rest of your balance is exposed. Next, the liquidation price guide confirms the stop sits before liquidation. Finish with funding rates and fees to work out the real cost of holding overnight or trading often.

Settings used by the live system

The platform places orders in cross margin (tdMode cross on OKX, marginType CROSSED on Binance). The recommended margin is 250 USDT, with 20x base leverage for BTC, 10x for altcoins and a 50x maximum; the actual position size is derived from the stop distance, so a wider stop means a smaller position.

Fees are estimated at the standard OKX and Binance rates: 0.02% maker and 0.05% taker, with a further 10% off on Binance when paying with BNB.

  1. What Is the Funding Rate, and Should Day Traders Care?

    What the perpetual futures funding rate is, how it is calculated, who pays whom when it is positive or negative, how often it settles, and when day traders should care: holding across settlement, what extreme rates reveal about crowding, and how funding shows up in live PnL.

Is higher leverage always more dangerous?
Not necessarily. Risk depends on notional size and stop distance: with the same loss budget, a tight stop allows a larger position and a wide stop requires a smaller one. The real danger is trading without a stop, or with a liquidation price closer than the stop.
Should I use cross or isolated margin?
Isolated margin caps the loss at that position's margin, while cross margin uses your available balance to defend against liquidation. When every trade has a stop, cross margin lowers the chance of being liquidated by a wick; without stops, isolated margin better prevents one trade from sinking the whole account.
