买卖信号

**买入信号：** - DRAWICON(A AND 短线做多>短线做空,短线做多+0.05,1) - 当短线RSI上穿中线RSI且短线做多>短线做空时，显示买入图标(1) **卖出信号：** - DRAWICON(B AND 短线做多<=短线做空,短线做空-0.05,2) - 当短线RSI下穿中线RSI且短线做多<=短线做空时，显示卖出图标(2) **辅助判断：** - STICKLINE柱状线颜色变化反映B1的多空状态和变化方向（红/黄/绿色） - 零轴线(0)作为多空分界线

用法

1. **适用场景**：该指标结合了双EMA趋势判断和RSI相对强弱指标，适合中短期交易决策 2. **买入条件**：当出现买入图标时，表明短线RSI上穿中线RSI，且短期趋势处于多头状态（短线做多线在短线做空线上方） 3. **卖出条件**：当出现卖出图标时，表明短线RSI下穿中线RSI，且短期趋势处于空头或调整状态 4. **注意事项**： - 需要结合零轴线位置辅助判断多空趋势 - STICKLINE的柱状颜色可作为辅助参考（红色代表上涨中继或反弹，绿色代表下跌中继或回调） - RSI参数使用了1-21周期的多个时间框架组合，短线RSI(5日平均)和中线RSI(15日平均)的交叉具有滞后性，需结合其他指标验证
