you suggest below and the EOD's matched.  When you do the set up as 
described below does AB take the real time data and do the coversion to 
EOD? If so how do you do it? If not do you get some other feed from 
eSignal?

  Herman,
   
  Did you do what I suggested ? I.e. creating eSignal database 
  with base time interval set to "EOD (daily)" ?

    <SPAN 
    class=531415316-15032004> 
    I run both 
    eSignal and QP2 data and am porting some mature QP2 EOD code to 
    eSignal to see if it can be enhanced with RT data. Before changing any 
    code I wanted to confirm identical EOD performance in both data 
    environments, I found huge discrepancies. Comparing daily OHLC prices 
    derived from eSignal RT data with OHLC data from QuotePlus I found that 
    taking a Random 20-day sample showed 38% disagreement between the two data 
    sources. Now the question arises as to which is the correct 
    one?
    <SPAN 
    class=531415316-15032004> 
    If you have both 
    data sources please let me know if you have noticed this discrepancy. I used 
    the following code snippets to illustrate this problem. I used two separate 
    AB instances; one configured for eSignal and one for QuotePlus. 
    Perhaps I am doing something wrong....I hope so!

    Many thanks for 
    any comments you can make,
