can't believe i'm dropping this now. bloomberg terminal for basis and funding arbitrage a lot of time and effort went into this, and here's what you get: - scanner for arb setups across 35 cexes and perp dexes - realtime parsing of 9300 unique pairs - bid and ask of both legs are accounted for, not just last or mark price - you can see real returns over 24h, 7d, 30d based on historically paid funding (not just converting current funding into APR) - ability to filter pairs by volume and open interest and most importantly for every pair you can open a detailed chart section that includes: - price chart (including bid ask) - historical in/out spread chart (based on real bid ask) paid funding chart - funding change chart (yes, it's always different and not always equal to funding paid) and yes, all of this is completely free link:
