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;

选股
K:=SLOPE(C ,7);

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); 
买1:CROSS(A2,A) AND A<50 ,COLOR00FFFF;
