买卖信号
1. **MACD金叉/死叉**：DRAWICON(CROSS(DIF,DEA),DEA,1)表示DIF上穿DEA买入；DRAWICON(CROSS(DEA,DIF),DEA,2)表示DIF下穿DEA卖出 2. **KDJ金叉/死叉**：DRAWICON(CROSS(K,D),D,1)表示K上穿D买入；DRAWICON(CROSS(D,K),D,2)表示D下穿K卖出 3. **MACD底背离**：DRAWTEXT(B1,DEA-0.20,'▲MACD底背')，当MACD出现底背离时买入 4. **KDJ底背离**：DRAWTEXT(B2,D-0.20,'●KDJ底背')，当KDJ出现底背离时买入 5. **金叉共振**：DRAWTEXT(B4,L-0.20,'★金叉共振')，当MACD和KDJ同时金叉时买入 6. **三线金叉**：A:=CROSS(DIF,DEA) AND CROSS(K,D) AND CROSS(J,D)，DRAWICON(A,LOW*0.98,1)表示DIF、K、J同时金叉时买入 7. **BXG选股信号**：FILTER(BB AND BD AND J>REF(J,1) AND REF(J,1)<REF(J,2),3)，表示满足5日内4天DEA上升、2天阴线、J连续两天上升后第三天满足条件
用法
1. **适用场景**：该指标为综合型指标，结合了MACD、KDJ、RSI三大常用指标，适用于中短线交易分析 2. **主要功能**： - 判断MACD金叉死叉及背离 - 判断KDJ金叉死叉及背离 - 多指标共振选股（金叉共振、三线金叉） - BXG用于筛选符合条件的股票 3. **注意事项**： - 底背离信号需要结合股价创新低但指标未创新低来确认 - 金叉共振信号可靠性较高，可作为重点买入参考 - 指标包含红色粗线（DRAWLINE）显示顶背离 - STICKLINE在BXG条件满足时显示红色柱子 - 建议结合
