Actually, really sorry you're the one confusing things further by accusing me of being incorrect trash? I know you can get cranky at times, but as Richard has mentioned above, and your links clearly re-iterate, the default location for trend lines, notations etc is in the ASX-PremiumData sub directory underneath the Amibroker directory.
There is nothing mentioned in my links to amibroker.com about any ASX-PremiumData. I was talking about
any AmiBroker databases. I was referring to AB's database concept. You didn't mention anything about trendlines being in an AmiBroker database. Where have you done so?
Instead you wrote this one
The data directory is purely the price database - no Amibroker notations etc in there.
Where you have seemed to refer to an AB database. If you didn't mean AB database then you should have pointed it out unmistakably!
I replied to that your comment with actual facts from AmiBroker manual...
"A database (or a workspace) is a directory that holds a set of binary files, which are stored in 0-9, a-z, '_' subdirectories. Those binary files hold quotes, symbol information, your studies (trend lines, Fibonacci stuff)."
Even Richard Dale was repeating it
"(e.g. a trendline on BHP is in the file C:\Program Files\AmiBroker\ASX-PremiumData\B\BHP)"
So manually drawn trendlines data or any other studies data are saved in AmiBroker database subfolder's binary sample symbol file 'BHP' or
any other symbol file
of an AB database. So studies are saved to a database only. Only there studies are getting stored but nowhere else. Please re-read your first post of this page, it is clearly misleading on that part.
Do you understand that the mentioned sample BHP file or any other symbol file (which are part of AmiBroker Database) do not only save price data but also store studies data? Yes? Fine, but then you should have been more precise.
The actual price database will typically be located in another directory well away from the executable. Obviously those can be user adjusted, however in my case the ASX-PremiumData is a sub folder under Amibroker, therefore I periodically backup my entire Amibroker (and sub folder) directories.
Yeah, and that subfolder (ASX-PremiumData) is an
actual AmiBroker database but not just some generic subfolder and once again it does
not just store price data! Also the location of any AmiBroker database doesn't matter. An AmiBroker database can be located where ever you want it to be located. It may be AmiBroker's main directory, it may be a different partition on your hard drive or it may be located on an external dropbox folder far away from AB installation folder (let's ignore any disadvantages of the last example).
The Norgate price database is typically in a completely separate directory called "Trading Data". I have frequently deleted the entire directory and re-installed when the odd price corruption has occured.
That data folder is not an AmiBroker database as mentioned by Richard Dale. I was talking about
AB databases. Since that "Trading Data" folder is not an AB database there is no AB studies data being stored in there.
On 2nd thoughts, I guess I did say in the Amibroker directory, not in a sub-dir beneath. Presumably that's what the excitement was about. All the discussion will be a success however if just one other user gets to salvage their precious notations data.....
You wrote a general statement about trendlines being part of AmiBroker directory. This is not the case if you choose a different location for your
AmiBroker database. Why? Because as we have learned.. studies are part of symbol files and as such are
part of an AB database. An AB database even after its first creation (which may be in AB directory or elsewhere) is
not bound to its creation place. It is
movable to any place after being created. And if you move an AB database and you have created manual studies for that AB database then such manual studies
get moved too since they are part of an AB database (whatever its name may be since you can give a database any name you want even after its creation) but they are nowhere else placed. An AB database may be located in AB directory or elsewhere.
As a summary if you delete a symbol file of an AB database or if you overwrite it by some file having the same symbol name then all your studies of the former file are removed too.
PS: please stop putting any fictional emotions into my posts. I am commenting on things and facts but not persons. I guess some people don't like facts that's why they try to distract by drawing emotion cards not being there.
