Rick,
 
SetForeign works ALWAYS provided that symbol 
exists.
SetForeign will return FALSE (or zero) in case when symbol 
does NOT exist
 
if( SetForeign("symbol") )
{
  // setforeign successfull - symbol 
exists
}
else

{
  // setforeign failed - symbol does NOT 
exist
}
Best regards,Tomasz

  Subject: RE: [amibroker] Re: Relative 
  Strength
  
  For 
  what it's worth... I have had trouble with setforeign too. It does not always 
  seem to work.
  <FONT face=Arial color=#0000ff 
  size=2> 
  I 
  have had better luck assigning the data to a variable:
  <FONT face=Arial color=#0000ff 
  size=2>Index1=Foreign("otc-c","C")
  <FONT face=Arial color=#0000ff 
  size=2>Index2=Foreign("SP-CP","C")
  <FONT face=Arial color=#0000ff 
  size=2> 
  And 
  then calculate relative strength using the variables.
  <FONT face=Arial color=#0000ff 
  size=2> 
  I've 
  not run this though IB, but it would be something like 
  this:
  <FONT face=Arial color=#0000ff 
  size=2> 
  <FONT face=Arial color=#0000ff 
  size=2>Period=10
  <FONT face=Arial color=#0000ff 
  size=2>R1=Index1/Ref(Index1,Period)
  <FONT face=Arial color=#0000ff 
  size=2>R2=Index2/Ref(Index2,Period)
  <FONT face=Arial color=#0000ff 
  size=2>RS=100*R1/R2
  <FONT face=Arial color=#0000ff 
  size=2>Plot(RS,"RELATIVE STRENGTH",Colorgreen,Stylethick)
  <FONT face=Arial color=#0000ff 
  size=2> 
  That 
  should get you started.
