把大智慧的凤凰线指标改成通达信的指标和选股公式

编写要求：

{n,1,1,30,1} xopen:=(ref(o,N)+ref(c,N))/2; xclose:=close; xhigh:=max(high,xopen); xlow:=min(low,xopen); volality:=ma(xhigh-xlow,8); 凰线:ma(xclose,5)+volality/2; 凤线:ma(xclose,5)-volality/2; bu:=cross(xclose,凰线); sel:=cross(凤线,xclose); var1:=barslast(bu); var2:=barslast(sel); drawicon(ref(var1,1)>var2 and var1=0,xlow,7),align1,valign0; drawicon(ref(var2,1)>var1 and var2=0,xhigh,8),align1,valign2; STICKLINE(xclose>xopen and var1xopen and var1xopen and var1var2,xclose ,xopen ,8,0 ),colorgreen; STICKLINE(xclose<=xopen and var1>var2,xopen ,xhigh ,0.5,0 ),colorgreen; STICKLINE(xclose<=xopen and var1>var2,xclose,xlow ,0.5,0 ),colorgreen; STICKLINE(xclose>xopen and var1>var2,xclose ,xopen ,8,0 ),colorblue; STICKLINE(xclose>xopen and var1>var2,xclose,xhigh ,0.5,0 ),colorblue; STICKLINE(xclose>xopen and var1>var2,xopen,xlow ,0.5,0 ),colorblue;

解答：

?N:=1;

XOPEN:=(REF(O,N)+REF(C,N))/2;
