Re: Tick Volume Problem in TS4

["Allan L. Kaminsky" <allank@xxxxxxxxxxxxxxxx>]

Thanks for your response. The reporting of the 'Volume' quantity in EL
is not dependent upon chart scaling. The same bug has, by sheer
coincidence, been reported within the last two hours under the article
entitled "MISSING DATA IN EASYLANGUAGE."

This is very serious. Volume is a primitive data attribute. The
underlying data is correct (it is not a data vendor problem). Any
indicator or system that uses volume appears to be at risk for producing
incorrect results / trading decisions.

I have called this in to Omega and am waiting for a call back.

My guess is that the code for TS segregates volume into Up and Down
volume, and that the Volume attribute is incorrectly picking up 'Up'
rather than 'Total' volume. This is potentially devastating to
indicators/systems relying on this being correct.
