在决策线公式中,加个蓝线上穿红线.且红线小于20

编写要求：

A1:=1; A2:=(5); A3:=(((2 * CLOSE) + HIGH) + LOW) / 4; A4:=LLV(LOW,34); A5:=HHV(HIGH,34); A6:=EMA((((A3 - A4) / (A5 - A4)) * 100),13); A7:=(EMA(((0.667 * (REF(A6,1))) + (0.333 * A6)),2)) * A1; 决策线:(EMA(A7,A2)) * A1,COLORRED; A8:=(HHV(HIGH,9)) - (LLV(LOW,9)); A9:=(HHV(HIGH,9)) - CLOSE; A10:=CLOSE - (LLV(LOW,9)); A11:=((A9 / A8) * 100) - 70; A12:=((CLOSE - (LLV(LOW,60))) / ((HHV(HIGH,60)) - (LLV(LOW,60)))) * 100; A13:=SMA(((A10 / A8) * 100),3,1); A14:=(SMA(A13,3,1)) - (SMA(A11,9,1)); A15:=IF((A14 > 100),(A14 - 100),0); A16:=(EMA((((A3 - A4) / (A5 - A4)) * 100),8)) * A1; A17:=(EMA(A16,5)) * A1; STICKLINE(((A16 - A17) > 0),A16,A17,3,1),COLORFFAA18; STICKLINE(((A16 - A17) = A19) AND (A21 = A20)) AND (A18 > A22)) AND (CLOSE > A21)) AND ((REF(A21,1)) = A19) AND (A21 = A20)) AND ((CLOSE / (REF(CLOSE,1))) >= 1.07)) AND (A24 0;} A30:=((((((A18 >= A19) AND (A21 = A20)) AND ((CLOSE / (REF(CLOSE,1))) >= 1.035)) AND (A24

在末尾增加一行

drawicon(cross(a16,决策线) and 决策线<20,a17,1);
