通达信MA3操盘主图指标（均线型）指标公式

买卖信号

1. **买入信号**： - L>REF(H,1)：最低价高于前一天最高价时买入（红色图标11） - CROSS(VAR2,MA(VAR3,6))：VAR2上穿MA(VAR3,6)时买入（图标1） 2. **卖出信号**： - H<REF(L,1)：最高价低于前一天最低价时卖出（绿色图标12） - CROSS(MA(VAR3,6),VAR1)：MA(VAR3,6)上穿VAR1时卖出（图标2）

用法

1. **适用场景**：中短期趋势交易，结合均线系统和超买超卖判断 2. **注意事项**： - 包含7条EMA均线（5/10/20/30/60/120/250日），可观察均线多头/空头排列 - VAR1、VAR2、VAR3为超买超卖指标，可结合STICKLINE颜色判断市场状态（红色为多头，蓝色为空头） - CDP系统提供支撑位（撑、底）和阻力位（阻、强）参考 - 图标信号需结合K线形态和成交量验证，避免假信号 - 250日均线（红色）为长期趋势分界线
