尝试用Tv写了一个基于EMA的策略，目前能做到简单的条件判断，EMA12上穿EMA144和EMA169的时候开多，EMA12下穿EMA144和EMA169的时候止损。开空则完全相反。 优势是可以抓住趋势，问题是在震荡中会不断止损，不能保证盈利，过程中还是需要人为介入。 把代码记录在这里，大家可以导入Tv自己尝试做一下回测，看看是不是启发： 做多的条件： //@version=6 strategy("EMA策略 - 做多", overlay=true, default_qty_type=strategy.percent_of_equity, default_qty_value=10) // 定义与开单相关的EMA周期 ema12 = ta.ema(close, 12) ema144 = ta.ema(close, 144) ema169 = ta.ema(close, 169) // 绘制与策略相关的EMA线 plot(ema12, color=color.blue, title="EMA 12", linewidth=2) plot(ema144, color=color.green, title="EMA 144", linewidth=1) plot(ema169, color=color.orange, title="EMA 169", linewidth=1) // 条件：EMA12向上穿越EMA144和EMA169 long_condition = ta.crossover(ema12, math.max(ema144, ema169)) // 平仓条件：EMA12下穿EMA144和EMA169 exit_long_condition = ta.crossunder(ema12, math.min(ema144, ema169)) // 开多逻辑 if (long_condition) strategy.entry("Long", strategy.long) // 平多逻辑 if (exit_long_condition) strategy.close("Long") 做空的条件： //@version=6 strategy("EMA策略 - 做空", overlay=true, default_qty_type=strategy.percent_of_equity, default_qty_value=10) // 定义与开单相关的EMA周期 ema12 = ta.ema(close, 12) ema144 = ta.ema(close, 144) ema169 = ta.ema(close, 169) // 绘制与策略相关的EMA线 plot(ema12, color=color.blue, title="EMA 12", linewidth=2) plot(ema144, color=color.green, title="EMA 144", linewidth=1) plot(ema169, color=color.orange, title="EMA 169", linewidth=1) // 条件：EMA12向下穿越EMA144和EMA169 short_condition = ta.crossunder(ema12, math.min(ema144, ema169)) // 平仓条件：EMA12上穿EMA144和EMA169 exit_short_condition = ta.crossover(ema12, math.max(ema144, ema169)) // 开空逻辑 if (short_condition) strategy.entry("Short", strategy.short) // 平空逻辑 if (exit_short_condition) strategy.close("Short")
