Cash & carry (spot-futures) basis scanner: buy spot, short perps, track funding, and exit on convergence with fee-aware net ROI and alerts.
Mastering Spot-Futures (Cash & Carry) Arbitrage
Spot-Futures arbitrage is the gold standard for delta-neutral investment. By purchasing the 'Cash' asset (Spot) and selling the 'Carry' (Futures), you create a position immune to crypto market crashes while earning high interest rates.
In contango, perps can trade at a premium to spot. The scanner surfaces basis gaps and helps you validate realistic net edge after fees and slippage.

Cash & Carry Workflow (Spot + Perps)
Step 1: Check Basis Spread
Find a positive basis (perp premium vs spot) and confirm net edge after fees and realistic slippage for your size.
Step 2: Buy Spot (Long)
Buy the asset on spot. Prefer limit orders and sufficient order-book depth to reduce slippage.
Step 3: Short Perps (Hedge)
Open an equal-size perp short to neutralize price risk. Keep low leverage and maintain a liquidation buffer.
Step 4: Close Both Legs
Exit on basis convergence (or risk changes). Close spot and perps close in time to avoid temporary exposure.

Maximizing Capital Efficiency
Utilize Portfolio Margin accounts (if available) to use your spot BTC or ETH as direct collateral for your short, reducing the need for idle USDT and boosting net ROI.
Risk Control & Margin Safety Management
The primary risk is a short liquidation during a massive vertical price spike. We recommend keeping your 'Health Ratio' above 2.5 by allocating sufficient USDT margin.

Execution Notes
Risks of SpotβFutures Arbitrage
This is one of the more stable arbitrage approaches, but risk is not zero. Funding can flip, execution can slip, and leverage can create liquidation risk if mismanaged.
Funding rate reversal
Funding can turn negative and reduce yield. Track funding continuously and define exit rules for rate flips.
Liquidation risk (avoidable)
The futures leg can liquidate if leverage is excessive. Use isolated margin and conservative leverage (often 1x) to keep a large buffer.
Basis/mark mechanics
Large dislocations can widen the basis temporarily. Monitor mark price behavior and avoid oversized positions during volatility spikes.
Exchange risk
Downtime and sudden parameter changes can impact hedged positions. Prefer top venues and diversify across exchanges when scaling.
