Cross-Exchange Arbitrage

What it is

If a major coin trades >0.15% wider on one CEX vs another — you get pinged. Buy on the cheap one, sell on the expensive one.

Why it matters

Risk-free profit if you act fast. Windows close in seconds though, so you need accounts pre-funded on both exchanges.

How to read the alert

Check fees FIRST — the spread has to beat your fee budget on both sides. Don't trust spreads >1% without manual check (usually data lag). Move fast: blocks of >0.3% on liquid pairs last <30 seconds.

Sample alert

🔀 SOL/USDT spread 0.31% · Bybit ↔ OKX · up from 0.08% baseline

Each alert includes

• Pair, two venues, which side to buy/sell
• Current spread % and how far above baseline
• Estimated profit after fees
• How long the window will likely persist
