在下面江恩轮动中出现红箭头时做个预警公式

编写要求：

VA:=BARSCOUNT(CLOSE)*3.142/180; AA2: SIN(VA*8)*100,LINETHICK2; AA3: COS(VA*8)*100,LINETHICK2; X1: 0; A1:SIN(VA*1)*100; A2:SIN(VA*2)*100; A3:SIN(VA*3)*100; A4:SIN(VA*5)*100; A5:SIN(VA*6)*100; A6:SIN(VA*7)*100; A7:SIN(VA*8)*100; A8:SIN(VA*9)*100; A9:SIN(VA*4)*100; VAR1:=MA(CLOSE,5); VAR2:=MA(CLOSE,10); VAR3:=MA(CLOSE,20); VAR4:=MA(CLOSE,30); VAR5:=(VAR1+VAR2+VAR3+VAR4)/4; VAR6:=(VAR5-REF(VAR5,5))/REF(VAR5,5)*1500; VAR7:=(VAR5-REF(VAR5,5))/REF(VAR5,5)*1500; VAR8:=EMA(VAR6,8); 底部注意: STICKLINE(VAR6>REF(VAR6,1) AND VAR6<0 AND VAR6REF(VAR8,1) AND VAR6<0 AND VAR6>VAR8,VAR8,0,3,0),COLORYELLOW; 买点: STICKLINE(VAR6>REF(VAR6,1) AND VAR6>0 AND VAR8<0,VAR6,VAR8,10,0); DRAWICON(FILTER(VAR6>REF(VAR6,1) AND VAR6>0 AND VAR8<0,30),-140,4); DRAWTEXT(FILTER(VAR6>REF(VAR6,1) AND VAR6>0 AND VAR8<0,30),-40,'买点'),COLORFFFFFF; 坚定持股: STICKLINE(VAR8>REF(VAR8,1) AND VAR8>0,VAR6,0,3,1),COLORRED; 谨慎观望: STICKLINE(VAR6REF(VAR8,1) AND VAR6>0,VAR6,VAR8,10,0); 果断持币: STICKLINE(VAR6

解答：

?VA:=BARSCOUNT(CLOSE)*3.142/180;

?AA2:=SIN(VA*8)*100,LINETHICK2;
