  - STILL Problems
  
  Bob,
   
  when I run a code like the one provided below, AB 
  successfully scans about 4-5% of my entire QP2 database and then crashes 
  telling me that GetExtraData failed plus somewhere in my code were bad 
  arguments.
   
  Please use the code provided below and tell me 
  if you encounter the same, if you don´t mind.
   
  Thanks

    I meant that

    In order see 
    what was happening, I scanned with IssueType Preferred; and imported the 
    list..
    Voila, the

    Hence Filter =

    "1";<SPAN

    Note, however, that this way is much slower than doing it in QP and 
    importing the watcchlist.

      Bob,
       
      glad you stepped in here.
       
      I used the 
      filter=getextradata("issuetype")=="p".
       
      Weird enough, AB starts checking, then 
      returns error as below.
       
      Would you mind checking if the code is 
      correct (i.e. finds ALL preferred) plus if you encounter the same error, 
      please????
       
      Line 2, Column 40:Filter= 
      GetExtraData("issuetype")==" 
      p";---------------------------------------^
       
      Error 18.GetExtraData failed
       
      Many thanks

          this might be the most efficient way to 
          go.
           
          Justwanted to play arount with the string

            not need to chug through your whole database checking all your 
            various criteria since every stock in your watchlist will meet all 
            your criteria.When doing scans and explores you simply point to this

            [amibroker] String question
            Hello,
             
            I want to exclude all preferred stocks 
            from my scan.
             
            In their symbols they either end with " 
            p" (space p) or with " p.." (space p followed by any other 
            letter).
             
            While the first may be excluded by<FONT 
            face="Courier New" color=#6600aa> 
            (<FONT face="Courier New" 
            color=#0000ff>StrRight<FONT face="Courier New" 
            color=#6600aa>(<FONT face="Courier New"

            color=#ff00ff>2) != 
            " P"
            how could exclude latter case since I don´t know which (if at 
            all) letter might follow??
            Thank you for your help
