#现货与合约策略 Spot and contract trading have different strategies. Spot trading, like the Martingale strategy, involves doubling purchases to lower costs, but one must be cautious of continuous declines; options spot hedging can reduce risks and lock in profits, requiring clear goals and careful selection of contracts and quantities. Contract trading includes strategies such as trend following, mean reversion, and arbitrage. Trend following profits in clear trends, but it's easy to incur losses when trends are not obvious; mean reversion is suitable for oscillation, but long-term trends are prone to misjudgment; arbitrage has low risk but limited opportunities. In addition, contract grid trading can be optimized through smart parameter recommendations, dynamic profit optimization, and other aspects.
