奥数老师选股公式

{涨停回踩选股公式}

MA10 := MA(CLOSE, 10);
MA20 := MA(CLOSE, 20);
MA30 := MA(CLOSE, 30);

{定义涨停：涨幅>9.5%且收盘为最高价}
ZT := (CLOSE / REF(CLOSE, 1) > 1.095) AND (CLOSE = HIGH);

{10日内有涨停（排除当天）}
HAVE_ZT := COUNT(ZT, 10) >= 1;

{当天阴线且缩量}
YINXIAN := CLOSE < OPEN;
SUOLIANG := VOL < REF(VOL, 1);

{前一日均线位置条件}
PRE_C := REF(CLOSE, 1);
PRE_MA10 := REF(MA10, 1);
COND1 := PRE_C > 0.98 * PRE_MA10;
COND2 := PRE_C < 1.02 * PRE_MA10;

{均线系统条件}
MA10_UP := MA10 > REF(MA10, 1); {10日均线向上}
COND3 := (MA10 - MA20) / MA20 < 0.05; {10/20均线距离}
COND4 := (MA10 - MA30) / MA30 < 0.10; {10/30均线距离}

{10日涨幅限制}
TEN_DAY_CHG := (CLOSE / REF(CLOSE, 10)) < 1.30;

{最终选股条件}
BUY_CONDITION:
    HAVE_ZT AND             {10日内有涨停}
    YINXIAN AND             {当天阴线}
    SUOLIANG AND            {当天缩量}
    COND1 AND COND2 AND     {前一日均线位置}
    MA10_UP AND            {10日均线向上}
    COND3 AND COND4 AND     {均线间距}
    TEN_DAY_CHG;            {涨幅限制}
