Up Volume Down Volume

I see on the saw the reference to the wiki that explains that historical total volume is recorded to the database as total volume and up volume, where down volume is stored as 0.
This sounds like a bug or flaw to me. I would like to have up volume stored as up volume and down volume stored as down volume.
Can you explain why you have it this way? There are some indicators that I am planning to write where I very much would like to know the proper historical up volume and down volume.
So I respectfully ask you to explain why you designed it this way, and when will you make it store up and down volume properly.

Regarding historical data:
IQFeed does not have a data field for up volume or down volume.
IQFeed has only Incremental Volume and Total Volume.

Well, i see up vol and down volume for the current bar in IQFEED, but not for the past bars.... Therefore I do think it offers support to some degree at least.
Which feeds are u saying does support up and down volume?
Enclosed is a screenshot of upvol and downvol showing up on the current bar of DMND this am.

IQFeed does not have a data field for up volume or down volume.
IQFeed has only Incremental Volume and Total Volume.
As far as I know IQFeed provides the bid and ask price at the time of the trade (both for historical tick data as well as realtime data), so it would be possible for MC to provide the information by calculating it. Something that needs to be done for 8.1 anyway, otherwise you wouldn't be able to provide historical delta information.

They definately should correct this in 8.1 , upvol and downvol are very useful pieces of information.

You did not read
my answers.
Up and down volume are provided and stored for realtime data only.
For minute-based and daily-based resolutions all historical total volume is recorded to the data base as total volume and is also recorded as up volume. Down volume is empty.
You can find more information in
the corresponding Wiki article.
If you collect the data in realtime-volume information will be saved to the database and available in the future.

1) No, but trade price, trade volume and bid/ask price at the time of the trade. So it could be calculated.
2) MC does this for you automatically.

No.
2) if not, how do I save the data realtime?
The data is
automatically saved into the database once you close MC and all of its applications.
You can plot the chart to get the data or
collect real time data without plotting.
3) which feeds offer historical upvol and downvol for stocks on minute and hourly timeframes?

Just spoke with IQFEED
Tech support states that the data is available in the stream, and that if the chart software provider wanted to, they deconstruct or construct it such that it would show up valume and dn volume
Basically it would be constructed out of the tick data. As a matter of fact, I was able to see up volume and down volume in tick charts, however I didnt see it in minute charts.
Is it possible for you to construct a minute chart from tick data?
Another way to construct this data would be look at historical time and sales data and then be able to construct the up volume and down volume.
So there are 2 ways that you can construct upvol and downvol historically for IQFEED
Figured it out

There is a way to get up vol and dn vol in mc on minute bars..
If you select build min and day bars using tick data option in the settings.
