RE: [amibroker] Calling all AB'ers interested in using CSI data

["Dave Merrill" <dmerrill@xxxxxxx>]

As I 
said, my email has gone out already, and anything CSI can do would obviously be 
good. However, I'm slightly confused about the nature and degree of the 
performance problem.
<SPAN 
class=642192323-30122003> 
Is the 
CSI API is too slow in general, or is it more that the penalty of calling it 
twice for adjusted and nonadjusted data makes it too slow? Isn't there a greater 
than 2:1 difference in performance between existing plugins that people do 
consider practical? Is it more than twice as slow to get both prices? Is a 
single call already unfortunately slow?

>This 
  is a call to all you folks interested in using CSI data.  I post this 
  here so that those not on the AB-dll list will be able to participate in 
  this "grass-roots" AB effort to help ourselves.Paul Binnell, 
  Paul@xxxxxxxxxxx, has created a great plugin to access CSI data, but the 
  CSI API is too slow for practical usage.  If enough current and 
  potential customers send an e-mail to rudi@xxxxxxxxxxx we can get some 
  traction on this, and hopefully be able to get our hands on what Chuck 
  describes to be some of the cleanest data to include delisted tickers 
  (which is also cheaper than QP for stocks only).Here is Chuck's 
  post to the AB-dll group indicating the exact verbage to send to 
  rudi@xxxxxxxxxxxxThanks for chipping in and helping us as well as 
  yourself.Warmest,GaryHERE'S CHUCK'S

  support follow-upIf everyone (potentially) interested in using CSI 
  data and/or Paul's plug-in would write to  rudi@xxxxxxxxxxx, we may 
  be able to put some pressure on CSI to help us out.What we want 
  Rudi to do is modify the API so that one call to it will return actual and 
  backadjusted prices or, alternatively, the ratio of same in the open 
  interest column.I have written to Rudi myself, but some support from 
  interested parties may support my suggestion that others are 
  interested.Cheers
