发给大家一个通达信支撑压力主、副图及选股指标，经测试无未来函数，希望助你投资成功。
压力线-支撑线及源码如下：
压力线:HHV(H,25),COLORFF00FF;
支撑线:LLV(L,10),COLOR00FFFF;
趋势线:SMA(MA((C-支撑线)/(压力线-支撑线)*4,5),5,1);
MA5:MA(C,5),COLOR00FF00;
MA10:MA(C,10),COLORFF00FF;
MA25:MA(C,25),COLOR0000FF;
K:=SLOPE(C,7);
DRAWTEXT(CROSS(K,-0.01),L*0.99,'买'),COLORFFFFFF;
AR1:=(C-LLV(L,18))/(HHV(H,18)-LLV(L,18))*100;
AR2:=SMA(AR1,9,1);
A2:=EMA(AR2,3);
A3:=EMA(A2,3);
A4:=EMA(A3,3);
A5:=EMA(A4,3);
AA:=EMA(A5,6);
A:=LLV(AA,13);
DRAWTEXT(CROSS(A2,A) AND A<50,L*0.98,'买1'),COLOR00FFFF;
买1:CROSS(A2,A) AND A<50,COLOR00FFFF;
买:CROSS(K,-0.01),COLORFFFFFF;
