The problem here is probably neither the software nor the hardware -
check the "middleware", the interface between the two. :)
When using the Security() function, make sure that there is sufficient
data in the referenced securities to match the loaded chart data,
otherwise errors will follow. One way around this is to restrict the
processing to the common valid data period as done here:
---8<----------------------------
Sec1:=Security("C:\MetaStock\Data\cbavp",C);
Sec2:=Security("C:\MetaStock\Data\cbavc",C);
SMA1:=Mov(Sec1,3,S);
SMA2:=Mov(Sec2,3,S);
valid:=Cum(IsDefined(SMA1+SMA2))>0;
same:=valid AND
(SMA1>Ref(SMA1,-1) AND SMA2>Ref(SMA2,-1)
OR SMA1=Ref(SMA1,-1) AND SMA2=Ref(SMA2,-1)
OR SMA1<Ref(SMA1,-1) AND SMA2<Ref(SMA2,-1));
{ +1= 100% correlation, -1= 0% correlation }
same
