Finding Arbitrage Opportunities

Overview

Compare one exact pair's best bid and ask across nine exchanges and compute every cross-venue spread, gross and net of stated taker fees. A triangular search checks three-trade cycles inside one venue.

Venues: Kraken, Coinbase, KuCoin, Gate, OKX, Bitfinex, Crypto.com, Binance, Bybit. Binance and Bybit refuse US networks (HTTP 451/403); the tool names them and carries on.

Pairs with different quote assets are never compared: BTC/USD against BTC/USDT measures the USDT/USD rate, not an arbitrage.

Prerequisites

• Python 3.9 or newer. Standard library only: no packages, no API keys.
• Network access to the exchanges' public endpoints.

Instructions

All commands run python3 ${CLAUDE_SKILL_DIR}/scripts/arb_finder.py. Every command accepts --format json, --fee VENUE=PERCENT (the actual account taker fee), --demo (bundled recorded data, marked on every line) and --timeout SECONDS.
