通达信OBV主力指标（趋势型）指标公式

买卖信号

**买入信号：** 1. 主力上穿散户且主力<-10：DRAWTEXT(CROSS(主力,散户) AND 主力<-10,-20,'升') 2. 底部信号：DRAWICON(底部 AND A31>REF(A31,1),25,1) 3. 主力上穿散户且散户>-35：DRAWICON(CROSS(主力,散户) AND 主力<-10 AND 散户>REF(散户,1)OR CROSS(主力,散户) AND 散户<-35,-15,1) 4. 探底信号：(MA(C,5)-C)/C>0.04 AND (MA(C,10)-MA(C,5))/MA(C,5)>0.04 5. 黑马信号：DRAWTEXT(CROSS(A11,黑马线)AND 黑马线<A51,黑马线,'黑马') 6. 追涨信号：DRAWTEXT(CROSS(黑马线,A51)AND 趋势线<80,黑马线,'追涨') 7. 大黑马信号：DRAWTEXT(CROSS(趋势线,0)AND 黑马线<40,5,'大黑马') **卖出信号：** 1. 逃跑信号：DRAWTEXT(FILTER(REF(黑马线,1)>90 AND A21<0,7),黑马线,'跑')

用法

该指标为综合型技术指标，包含主力资金、散户动向、黑马线、趋势线等多维度分析。适用于中短线交易择时。主要特点：(1)通过"主力"与"散户"指标交叉判断资金流向；(2)"黑马线"用于捕捉潜在黑马股；(3)"趋势线"判断中长期趋势；(4)"探底"信号用于判断短期超跌反弹机会；(5)红色STICKLINE表示B7上升，黄色表示B7下降。注意事项：需结合大盘走势和成交量综合判断，避免单一信号操作；"跑"信号出现时需及时止盈止损。
