A live cross-exchange scanner for price spreads and funding rates. Built on real bid/ask prices — not stale last-trades. Honest about slippage, lendability, and what's actually tradeable.
Crypto arb data is full of mirages. Stale prices, thin books, coins you can't even short. Skyptra fixes all three.
Most scanners use last-trade prices, which can be stale by seconds. By the time you act, HFT has closed the gap. We compute from real-time bid/ask — what you can actually execute.
A "1% spread" on a thin-book coin becomes 0% after fees and slippage. We show fee-adjusted net edge and flag low-liquidity routes so you don't get rugged by the order book.
A -5% funding looks juicy, but if the coin isn't lendable on the exchange, you can't capture it. We track funding intervals (1h/4h/8h) normalized to per-8h equivalents so they're actually comparable.
Every feature comes from a real trading bug I ran into and got tired of.
We compute spread from actual bid and ask — the prices you can really sell and buy at. Not stale last-trade snapshots.
See how long an opportunity has been visible. A 1% spread that's been live for 30+ seconds is more real than a flash that just appeared.
Most bots only watch Binance ↔ OKX. We show OKX → Gate routes that the 2-exchange crowd misses — often the biggest opportunities.
Plug in your notional. See the actual dollar profit, after fees, for each opportunity. Stop doing math in your head.
Funding cycles differ across coins (1h, 4h, 8h). We normalize everything to per-8h equivalents so a 0.5%/4h coin is correctly compared to a 1%/8h coin.
Spreads under 0.3% are usually eaten by HFT before retail can fill. We label them so you don't waste time chasing ghosts.
The full scanner runs in your browser, refreshes every 5 seconds, and shows every opportunity across all 3 exchanges.
Three steps. No magic. Just transparent math.
Real bid, ask, last, volume, and funding rates from Binance, OKX, and Gate. ~600 coins tracked simultaneously.
Subtract fees, estimate slippage, normalize funding intervals, track persistence. Show net edge — not gross fantasy.
