About this tool
This tool screens funding-rate differences for the same asset across trading venues to surface where perpetual-swap funding diverges. It helps traders exploring delta-neutral funding strategies see where the rates are widest without checking each exchange by hand.
It compares the funding rates each venue charges on perpetual contracts and highlights the spread between them for a given coin. A funding-arbitrage idea typically involves holding offsetting long and short positions on different venues to collect the difference, while accepting execution, fee, and margin costs that eat into that spread.
Frequently asked questions
What is a funding rate?
Funding is a periodic payment exchanged between long and short holders of a perpetual contract to keep its price aligned with the spot market. When the rate is positive, longs pay shorts, and when it is negative, shorts pay longs.
How does funding-rate arbitrage work?
The basic idea is to hold offsetting positions so you are market-neutral while collecting the funding difference between venues or between perpetual and spot. The realistic edge is small because fees, slippage, and margin requirements reduce the raw spread, and rates can change each funding period.
What is a good funding rate to look for?
There is no fixed 'good' number, since funding varies constantly with market sentiment and leverage demand. For arbitrage, what matters is the spread between venues being large enough to cover trading costs, not the absolute rate on any one exchange.
