Perp funding rate arbitrage checklist between crypto exchanges turns a visible rate gap into an executable trade or a pass. The practical workflow is to confirm whether a funding-rate spread survives fees, slippage, withdrawal times and exchange risk before committing capital.

CryptoSigy covers this as execution quality. A trader seeing different funding rates on Binance and Bybit for the same perp pair has found a pricing gap, but the gap is only profitable if the costs and risks of the cross-exchange route are smaller than the expected carry.

Calculate The Net Carry After All Costs

Start with the funding-rate difference between the two venues. Convert the eight-hour or four-hour rate to an annualized percentage and subtract the taker fees for opening both legs. Add withdrawal fees, minimum withdrawal amounts and the spread cost of converting any intermediate stablecoins.

A two-percent annualized gap that costs one percent to enter and one percent to maintain is not an arbitrage. It is a fee transfer from the trader to the exchanges. The net carry must be positive after every fee, and the margin of safety should be wide enough to absorb one or two unfavorable funding periods.

Check Position Size Against Exchange Liquidity

The spread exists on screen but may not support the intended size. Check the order book depth on both venues at the entry price. If one leg requires crossing multiple levels, the real entry cost is higher than the top-of-book quote.

Also check whether the exchange has a maximum position size or a different margin requirement for the pair. A rate that works for one Bitcoin of notional may fail for ten. Position size should be tested against the book before the trade goes live.

Account For Withdrawal And Rebalancing Time

Cross-exchange arbitrage requires capital on both venues. If one leg accumulates profit faster, the trader needs to rebalance. Withdrawal times, network fees and exchange processing delays create windows where the position is under-hedged.

A funding-rate spread that looks stable over eight hours can become negative during the rebalancing window. The trader should know the worst-case funding payment during the longest expected withdrawal time and include that in the net carry calculation.

Monitor Funding Rate Cap And Floor Rules

Exchanges use different funding-rate formulas. Some cap the rate at a percentage of the maintenance margin. Others use a moving average that smoothes spikes. A spread driven by a temporary spike may revert before the position has time to earn the expected carry.

Also check whether the exchange reserves the right to change funding intervals, rate caps or calculation methodology. A regulatory or risk update can close the spread without warning, leaving the trader with two open positions and no carry advantage.

  • Calculate annualized net carry after taker fees, withdrawal costs and spread.
  • Test position size against real order book depth on both venues.
  • Include rebalancing time and worst-case funding payments in the model.
  • Track exchange-specific funding formulas, caps and methodology change risk.
