Re: [amibroker] Does anyone use Foreign function?

Hello,
 
The code you have given works provided you have ^GSPC present 
in your database.
 
If the symbol given in Foreign function does not exist you get 
-10000000000

Subject: [amibroker] Does anyone use 
Foreign function?

I have following codes:
 
x=Foreign("^gspc","C",fixup=1);y=(x/Ref(x,-1) 
- 1)*100;z=MA(y,40);Plot(z, "",1,1);
 
My result is ko(or other symble)=-100000...00.00, 
does anyone have some different experience?Your
