Arbitrage
Current cross-exchange spreads with a profit calculator (spot, perp, funding, depth).
Live: the cross-exchange spread right now. The upper bound hides suspiciously large spreads — usually ticker collisions rather than real arbitrage.
Prices and spreads refresh automatically every ~30 seconds. Order-book depth loads as you scroll to each card — that's why new cards show “…” first.
No spreads above the threshold (markets are efficient right now).
