Tomasz,
   
  Since you mentioned 
  it…
   
  Yahoo provides only adjusted close 
  - as for H/L/O you have to adjust yourself. 
  But.. AmiBroker's importer 
  (including AmiQuote 'auto-import') does that automatically for 
  you.

  Since the adjusted 
  close is used to compute the adjustments for H/L/O we are stuck with 
  bad data since Yahoo 
  has only 2 decimal places in adjusted close. For example, Yahoo data for CSCO 
  shows $0.08 adj. close for all actual prices between $23.00 and 
  $24.00. Screen shots below.
  
Also, the 
  volume info is distorted, possibly due to 32 
  bit integers? (Note 
  negative values.)
   
  Assuming this is 
  correct, I will lodge a complaint with Yahoo.
