Hi
@ducati916,
I'm a noob, but have been reading up on Amibroker and Norgate, so perhaps some of the below will help? This assumes you're using Norgate Data; if not, then perhaps this may help others.
The below link shows the "extras"/"fundamentals" data available in Norgate Data (Gold and Platinum subscription level) (scroll the page as required):
https://norgatedata.com/data-content-tables.php#current-fundamentals
I opened the data viewer in Norgate Updater:
View attachment 105427
but unfortunately it is static, not dynamic, and doesn't list all the additional information. I was hoping to be able to scroll to the right (a lot) to see all the extras.
I opened the Symbol Information window in AB:
View attachment 105428
which does appear to list (all???) the additional information, but with data labels rather than data names. For the data names I would use the Norgate URL above.
In the AB Chart window:
View attachment 105429
is the Norgate Data folder, I assume created when you install the Norgate Data Updater, or perhaps the ND AB plugin.
I dropped all these on a blank chart, then selected Edit Formula..., but IMO it's easier to just view the AFL in an external editor. I like Visual Code, but Notepad works (is notepad the best Microsoft can do after 20-30 years???)
On my installation, the Norgate Data AFL is located at C:\Program Files\AmiBroker\Formulas\Norgate Data.
Viewing those files in Visual Code, the main file seems to be C:\Program Files\AmiBroker\Formulas\Norgate Data\Norgate Data Functions.afl, as this is #included in all the remaining files.
Those functions look to just be helper functions wrapped around the AFL GetExtraData function, for example GetExtraData("NorgateBusinessSummaryLastUpdate"), with the rest of the AFL being outer functions calling the helper functions (for example to Plot() something).
IMO the documentation for the extra data could be better on the Norgate website, but this AFL, plus a bit of hacking, may get you what you need.
To me, it doesn't look like Norgate Data Functions.afl is complete, compared to the extra/fundamental data available in the URL above. Plus all the variable names in the code are prefixed with "Norgate", none of which are noted in the Norgate URL as the variable names.
For example, in the URL, search Metadata, Security Information - Text, FieldName = "Business Summary", but the AFL code says "NorgateBusinessSummary". See the function NorgateBusinessSummary() in Norgate Data Functions.afl.
All of this is untested
- I'm making the assumption that the AFL provided by Norgate, um, works
If I were to augment their code, I wouldn't edit their files directly, as they might get overwritten if I re-installed Norgate Data Updater. Instead, I think I would create another folder under C:\Program Files\AmiBroker\Formulas, such as CustomNorgateData or MyNorgateData or somesuch, then put my code there. And have a good backup somewhere in case I reinstall AB and my custom location disappears! I'd then follow a similar pattern as Norgate; have one uber-AFL file with all my helper functions, then other functions that call them (such as to plot or filter). I may be wrong on this best practice approach due to my AB inexperience, but I'm sure someone will correct me if I am (and I'll learn something in the process).
I believe you are a discretionary trader, but perhaps this will help you write up some filtering rules that would save you a lot of time when hunting for your next winners?
Hope this helps,
Linus
