Risk Management

Understanding and Mitigating Risks

While arbitrage is often called "risk-free profit," reality is more nuanced. Execution risk exists when trades fail or partially fill. Network delays can cause spreads to close before completion. Exchange outages or maintenance can trap funds temporarily. Smart traders plan for these scenarios.

Position sizing is crucial for sustainable arbitrage. Never risk more than you can afford to lose on a single trade. Even with careful planning, unexpected events can cause losses. Start small, prove your strategy works, then scale gradually.

Diversification across exchanges and strategies reduces concentration risk. If one exchange has issues or one strategy stops working, others can compensate. Build redundancy into your trading system - backup exchanges, alternative routing, failover procedures.

Monitor your performance metrics constantly. Track your win rate, average profit, and maximum drawdown. If metrics deteriorate, stop trading and investigate. Markets evolve continuously, and strategies that worked yesterday might fail today.

Capital Efficiency and Leverage

Flash loans revolutionize arbitrage by eliminating capital requirements. Instead of needing $100,000 to capture a $1,000 spread, you can borrow the capital for just the duration of the trade. This democratizes arbitrage for traders without large capital reserves.

However, leverage amplifies both profits and risks. Failed flash loan transactions still incur gas fees. Complex multi-step arbitrages have more points of failure. Always test strategies on testnet before risking real funds on mainnet.

Calculate your break-even spread carefully. Include all fees: platform fees, network gas, exchange fees, and potential slippage. Only execute trades where expected profit significantly exceeds costs. Building in a safety margin protects against unexpected expenses.
