CEX Spot Arbitrage Scanner — Binance, Bybit, OKX, Kraken, Gate

What does CEX Spot Arb Scanner do?

CEX Spot Arb Scanner pulls real-time bid/ask quotes from five major centralized exchanges — Binance, Bybit, OKX, Kraken, and Gate.io — and calculates cross-exchange spot price arbitrage opportunities for any list of cryptocurrency pairs. For each coin it computes the gross spread, fee-adjusted net yield, minimum capital requirement, execution feasibility, exchange counterparty risk, liquidity symmetry, and a sustainability score that indicates whether the spread is structural or likely to close within seconds.

Why use CEX Spot Arb Scanner?

• All five major CEXs in a single call. Instead of polling Binance, Bybit, OKX, Kraken, and Gate.io separately and reconciling the results yourself, one actor run gives you a unified, comparable dataset with per-exchange bid/ask prices.
• Fee-aware profitability, not just raw spread. The arb_net_yield_pct field deducts taker fees, estimated slippage, and withdrawal costs from both legs so you see the actual pocket-able profit — not the headline spread that evaporates after fees.
• Know before you trade: execution window and capital floor. The execution_window field (seconds / minutes / hours / persistent) and capital_requirement_usd tell you whether an opportunity requires sub-millisecond algo execution or is wide enough to capture manually.
• Counterparty risk baked in. Each result carries an exchange_risk_score (0–100) and sustainability_score so you can weigh exchange reliability against the apparent yield.
• No API key required. All five exchange APIs used are public, unauthenticated endpoints — no credentials to manage.

FAQ

Q: Does the actor actually execute trades or move funds? A: No. The actor is read-only. It fetches public order-book quotes and computes analytics only. No accounts, API keys, or wallets are connected.

Q: Why might arb_net_yield_pct be negative even when raw_spread_pct is positive? A: After subtracting taker fees from both exchange legs, estimated slippage, and withdrawal costs (which are fixed regardless of trade size), many spreads become unprofitable for small trade sizes. The capital_requirement_usd field shows the minimum size needed to break even.

Q: How accurate are the fee and withdrawal cost estimates? A: The actor uses typical published taker fee tiers for each exchange and median withdrawal fee estimates. Actual costs vary by VIP tier, withdrawal method, and network congestion. Treat the outputs as screening signals, not guaranteed profit calculations.
