Dave,
Currently, the CSI API makes the plugin impractical due to slow speed. An exploration of C > 5 and MA(V,21) > 100000 takes well over half an hour via the CSI plugin vs <5 min for the same watchlist of QP data.
In terms of the technical aspects, I'd say post to the amibroker-dll group or Paul directly. Your added brainpower to the effort will be appreciated.
Regards,
Gary

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.
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 POST:-----Original
