1. Funding Rate Arbitrage (Delta Neutral Hedging)

Principle: When the perpetual contract funding rate is positive, buy spot + short the contract to earn funding; when the rate is negative, reverse the operation.

Case: In June 2025, the BTC spot premium was 0.4%, holding 10 BTC hedging positions earned 450 USDT in funding rate income across 3 times, price difference convergence earned another 300 USDT, total income 680 USDT (after deducting fees).

Automated Tool: Binance has launched the **Funding Rate Arbitrage Bot**, supporting fully automated hedging without manual operation.

2. Interperiod Contract Arbitrage (Term Structure Arbitrage)

Applicable Scenario: When the current contract premium exceeds 1.5% of the next season contract (Contango structure), short the current season + long the next season.

Case: In March 2025, the BTC current contract premium was 2.2%, opening a position with 20x leverage, closing when the price difference shrank to 0.8%, yielding a return of 28%.

Key Risk Control: Set a price difference stop-loss (e.g., force exit when the current contract price difference exceeds 2.5%).

3. Grid Arbitrage (A Tool for Volatile Markets)

Operation: Set 100 grids for ETH in the range of 2000-3000 USDT, with 6x contract leverage, the greater the volatility, the higher the profit.

Profit Verification: A user with a principal of 2000 USDT opened an ETH grid, with 300 USDT arbitrage profit in 1 month (unrealized gains not counted).

Optimization Suggestion: Increase positions every 10% drop and narrow the grid range to enhance capital utilization.
