Choosing the trading pair for #交易对 is like equipping a strategy with an "engine"—choosing the right one can enhance efficiency, while choosing the wrong one may render the strategy ineffective. The trading pair is the "invisible leverage" of the strategy, and selection requires a three-dimensional assessment:

❶ Risk dimension (isolation of price fluctuations of the asset) → Choose stablecoin pairs

❷ Liquidity dimension (depth/slippage prediction) → Avoid thin markets

❸ Strategy dimension (directional/arbitrage) → Match tool attributes
