Usage

How can I improve the update and data access speed?
NDU started to download an historical database and then stopped. What could the problem be?

WatchList Library

Where are my Watchlist Library files stored?
How do I transfer the NDU Watchlists created on one machine to the Norgate Data database on another machine?
My Watchlist Library includes watchlists for "Current & Past" index constituents. To restrict a back-test to historical index constituents, do I simply reference such a watchlist in a back-test?
When a symbol in a watchlist for "Current & Past" has a date suffix - like XYZ-201506 - does the suffix indicate when the stock was removed from the index?
Why can't I filter US delisted stocks by exchange?
Why does the S&P 500 Watch List contain more than 500 tickers?



Installation

If I install NDU under a supported but older version of Windows, will it work just as well?

It should. But you need to make sure that your version of Windows has been activated and kept up-to-date with critical updates. In particular, NDU can work under Windows 8.1 but not under Windows 8.

Can I install NDU on a Mac?

Not directly. NDU will only work under Windows. However, you can run NDU indirectly on a Mac via Windows virtualization software ("Windows Emulators") such as Parallels Desktop, VMWare, VirtualBox etc.

I've stopped updating from one of my two computers, so why am I prevented from installing on another?

We don't track individual machines - instead we keep count of the total number of machines that have logged in. If you want to abandon one of two existing installations, and install on a new machine, the process is to notify us so that we can re-start the count. Ask us to "reset my hardware keys" or "restart my machine count". As soon as 2 machines have logged in again, the limit has been reached again (we don't care which ones they are).

I have installed the NDU database on d: drive. Why am I getting a pop-up warning about free disk space on c: drive?

"Temp files" are typically directed to a Windows folder on c: drive by default.
After NDU has been installed, it requires a minimum of 500 MBs of free disk space on c: drive to keep functioning.
We provide a facility to give "advance warning" about current space on c: drive (Settings > Notifications). You can either untick the facility or set the threshold to suit yourself.

Database

How can I find my Norgate Data database?

You can find the location of your database by opening NDU and clicking on the Database tab or on Settings > Database Location. To open the folder, go Settings > Database Location and click "View Database folder contents".
Please note that the default database folder "c:\ProgramData\Norgate Data" might be hidden by Windows and therefore not shown in Windows Explorer.

How do I change the Database Location?

See the instructions provided here.

Can I search the Database?

Yes. The Data Viewer allows you to search by symbol or name. To do a refined search with filtering, use the Watchlist Library interface.

Do I need to keep a back-up copy of the Database?

Generally-speaking, you don't need to keep a back-up of the entire Database folder. If any database goes missing or becomes corrupt, you can click on the Database tab in NDU to download a replacement. However, you should keep a particular back-up of the "Watchlists" sub-folder to insure against accidental loss of files you have created in the Watchlist Library. See: "Where are my Watchlist Library files stored?".

The Database tab shows that all my databases are marked as "Corrupt" and downloading a database doesn't fix it. What can I do?

Click on Settings > Database Location > View Database folder contents and then close NDU.
Find the file core_ngdb in the database folder and delete it.
Then open NDU again and do a data update (which should deliver a replacement).

Is the NDU database static with regard to historical data?

No. Corrections come through to us from our primary upstream suppliers and these are transmitted automatically. Other errors and omissions are corrected by us as soon as they are discovered.

For stock market data, corrections may apply to any number of things, including:
