The core of the #套利交易策略 arbitrage trading strategy is **to take advantage of temporary market price imbalances to obtain almost risk-free profits**. Its core logic is **to simultaneously buy undervalued assets and sell overvalued assets**, locking in the price difference profits. Common forms include:

1. **Statistical Arbitrage:** Based on historical statistical models, pair trading related assets (such as stocks), betting on price deviations returning to the mean.

2. **Futures-Spot Arbitrage:** Utilizing discrepancies between futures prices and spot prices (basis anomalies), conducting opposite operations in both the futures and spot markets.

3. **Cross-Market Arbitrage:** When the same asset has price differences across different exchanges or markets, buy low and sell high.

**Key Points:**

* **Low Risk (Theoretical):** Relies on instantaneous hedging, with minimal market risk exposure.

* **Instantaneity:** Opportunities are fleeting, relying on high-speed trading systems and algorithms.

* **Small Profits:** Per transaction profits are thin, relying on high frequency or large capital amounts.

* **Practical Risks:** Execution risks (slippage, liquidity), model risks (statistical failures), and financing costs are key challenges.
