Funding arbitrage screener settings

Written by JustScreener Research Team Last updated August 18, 2026

The funding rate for the same pair differs between exchanges. If longs are paying on one venue while shorts are paying on another, you can open opposite positions of equal size: price stops mattering and the rate difference remains. The screener looks for pairs where that spread is large enough.

The screener answers one question: where the spread is right now. It does not account for fees, the cost of moving collateral between exchanges, or the risk of one leg being liquidated. Those costs eat a small spread entirely — which is why the threshold is worth setting with room to spare.

Thresholds: spread and stability

The spread is set in basis points: 10 bps means 0.1 percentage points of rate difference. The stability requirement answers a different question: how long the spread must hold before it is reported. An instantaneous difference is worth nothing — it can vanish while you are opening the second leg.

Which pairs to track

The pair universe matters more than it looks. The widest spreads almost always show up on obscure coins — exactly where there is nowhere to open the opposite leg at the size you need. Limiting to the top hundred leaves pairs where the trade is actually executable.

Limits: how many signals you are willing to read

A spread lives for hours while the check runs every minute — without a pause the same opportunity keeps arriving over and over.

Filters: which coins to count

Liquidity filters here are not noise protection but an executability check: both legs have to be opened and eventually closed, and on a thin contract the exit costs more than the whole spread earned.

Ready-made combinations

Liquid majors. Spread from 10 bps, stability of 3 minutes, top hundred pairs. Few signals, but each one is executable without slippage.

Wide search. Spread from 25 bps, all pairs. More opportunities, but each needs a separate check of order-book depth on both venues.

Your own list. Spread from 15 bps across the coins you already hold deposits for on both exchanges. The most practical option: a spread that needs no transfer can be taken immediately.

Common setup mistakes

A spread threshold set too low. A few basis points do not even cover the fees for opening two positions.

Zero stability. You get a signal about an instantaneous divergence that is gone by the time the second leg opens.

All pairs, no filters. The most tempting spreads turn up on contracts where your own size moves the price.
