我们可以把交易系统的抽象理解为:



每笔期望收益 = 胜率 × 每次盈利金额 – 失败率 × 每次亏损金额,再简化就是:每次赚的钱,减去每次亏的钱之后平均值。
这里套入三个角色:
1. 散户:胜率45%,期望收益 = 0.45 × 1.5 – 0.55 × 1 = +0.125

2. 普通交易员:胜率50%,期望收益 = 0.50 × 1.5 – 0.50 × 1 = +0.25

3.职业交易员:胜率55%,期望收益 = 0.55 × 1.5 – 0.45 × 1 = +0.375

你可以看到,从散户到普通交易员,胜率+ 5%,收益就翻倍,胜率+10%,期望值却涨了200%,差距远比想象大...#特朗普称伊朗战事接近尾声
