高点下跌10%给出买字信号

在每次从近期高点下跌10%的时候买入一定数额 在次从高点下跌在买入 保持个低成本不会深度套牢

爱约股解答：

DRAWBAND(ZIG(3,10),RGB(255,255,0),MA(ZIG(3,10),2),RGB(136,136,136));
A1:=ZIG(3,10);
A2:=MA(ZIG(3,10),2);
TJ:=REFX(CROSS(A2,A1),1);
TS:=BARSLAST(TJ);
XIN:=CROSS(COUNT(CROSS(C<REF(C,TS)*0.9,0.5),TS)=1,0.5);
DRAWTEXT(TJ,H*1.002,'高');
DRAWTEXT(XIN,L*0.98,'买');
DRAWKLINE(HIGH,OPEN,LOW,CLOSE);
