    Subject: [RT] Data question
    
    I have a question about my data 
    integrity.  I have a system that buys and sells QQQ on the 
    opening.  It's based on price and volume of QQQ and DIA.  I get my 
    EOD data from Worden brothers and run the system in 
    SuperCharts.
     
    I assumed the open price on QQQ from 
    Worden Brothers was real.  Yesterday 4-11-01 my purchase of QQQ through 
    Brown & Co. was at 42.20 on the opening.  Worden brothers (and 
    Yahoo's) opening was 42.16.  Brown & Co. says the opening was 
    42.20.  Worden brothers can't explain the difference.  The AMEX 
    website doesn't give the opening.
     
    I figure the problem is composite 
    opening price vs. AMEX opening price.  
     
    Can anyone tell me what the AMEX 
    opening price of QQQ was 4-11-01 ?   The price difference wasn't 
    significant but I question the integriry of my system based on backdata 
    obtained from Worden Brothers.
     
    Any comments or 
    suggestions?                
    Thanks in advance.
