Question

通达信 选股公式：股价上穿20日均线后的一到三天缩量回踩，且收盘价不破20日均线，请高手赐教！谢谢！

Answer 1

T1:=CROSS(C,MA(C,20));
T2:=BARSLAST(T1)<=2;
T3:=(C-MA(C,20))/MA(C,20)*100<=2 AND C>MA(C,20);
XVOL:=IF(CURRBARSCOUNT=1 AND PERIOD=5,VOL*240/FROMOPEN,DRAWNULL);
T4:=XVOL<REF(V,1)*0.8;
XG:T2 AND T3 AND T4;
如果是盘后选股的话，t4:=v<ref(v,1)*0.8;如果要盘中未破过20日线，请在t3最后加上L>=ma(c,20)

Answer 2

a:=cross(ref(c,3),ma(c,20));
B:=VOL<REF(VOL,1);
xg:a and COUNT(B,3)=3 and c>ma(c,20);

Answer 3

COUNT((C-MA(C,25))/MA(C,25)*100>0,10)>=10 AND ABS(C-MA(C,25))/MA(C,25)<0.01;

Answer 4

A:=cross(ref(c,3),ma(c,20));

xg:a and COUNT(B,3)=3 and c>ma(c,20);

Answer 5

COUNT((C-MA(C,25))/MA(C,25)*100>0,10)>=10 AND ABS(C-MA(C,25))/MA(C,25)<0.01;
