指标策略--通达信指标分享
上期经典指标："擒妖策略，趋势潜伏信号，主力控盘标记（玫红/紫K线），主副图选股（含源码）"
01指标简介：
使用说明
指标公式的示例描述：
一、主图指标公式（"高量三阴突破"）
{主图指标参数：N（高量周期默认20日）}N:=20;
{高量阴线识别}
HIGH_VOL:=V=HHV(V,N) AND C<O;
BIG_BODY:=(O-C)/REF(C,1)*100>=3; {实体跌幅≥3%}HIGH_VOL_DAY:=HIGH_VOL AND BIG_BODY;
{缩量至1/3以下}
COND_VOL:=V<REF(V,BARSLAST(HIGH_VOL_DAY))/3;
LOW_VOL_DAY:=COUNT(COND_VOL,BARSLAST(HIGH_VOL_DAY))=1;
{突破信号识别}
BREAK_HIGH:=C>REF(H,BARSLAST(LOW_VOL_DAY));
{绘图函数}
DRAWICON(LOW_VOL_DAY,L*0.98,38); {红色三角}
DRAWICON(BREAK_HIGH,H*1.02,11); {红色箭头}二、选股指标公式（缩量买点）解析
{选股指标参数：N（高量周期默认20日）}
N:=20;
{寻找最近高量阴线}
HIGH_VOL:=V=HHV(V,N) AND C<O;
BIG_BODY:=(O-C)/REF(C,1)*100>=3;
HIGH_VOL_DAY:=HIGH_VOL AND BIG_BODY;
{验证时间顺序}
DAYS_SINCE:=BARSLAST(HIGH_VOL_DAY);
VALID_DAY:=DAYS_SINCE>=2; {排除当日高量}
{缩量条件}
COND_VOL:=V<REF(V,DAYS_SINCE)/3;
{排除已突破情况}
NO_BREAK:=HHV(H,DAYS_SINCE)<REF(H,DAYS_SINCE);
{最终选股条件}BUY_SIGNAL:VALID_DAY AND COND_VOL AND NO_BREAK;
