Subject: RE: Understanding Categories
was: Re: [amibroker] Importing data into Amibroker
Hello Tomasz,thanks for the reply.I have
read the tutorials. printed out the manual all 300 plus pages, readit
twice and left it at work over the weekend so cant refer to it now
excepton the online version.I understand about the metastock
plugin and set up a database using themetastock plugin.However, I
have tried to follow these instructions and cam up with
theseproblems.I imported one of my data directories. ASX. The data
was placed in the ALLdirectory and in Group 0 and Market 0.I
changed group 0 and market 0 into ASX Equities using symbol
categories.I then tried to import my directory for London Stock
Exchange. Usingfile->Database settings->Configure am I supposed to
add further directoryfolders to this?? Where do they go? The yseem to get
merged into All andASX?? They certainly did not make another directory for
themselves.I set bars to 100000 to ensure all data from my files was
imported. is thatcorrect? Now (even though the data goes back say 20 years
) the tree takesforever to initialise.I do not understand what
process to do what I want to do.I want to import metastock files for 8
different folders (ASX, LSE, NYS,etc) 8 exchanges.I want them to
be within their own directory called (ASX, LSE, NYS,etc)under
markets.Then I want to import data from another database directory for
my futuresdata and put them in their own market name.Later I
will go through these directories and select top 100 etc and putthem into
a group called top 100 so that should not bea problem.However, at this
stage I cant see how to import the data in the firstinstance. LSE data I
have no idea where it is since I would have to trollthrough the ASX file
to locate their codes I guess.-----Original

AmibrokerImportance: HighHello,First you should really
read TUTORIAL and use METASTOCK PLUGIN<A
href="">http://www.amibroker.com/guide/h_extsources.htmlto
read MS database directly (so you don't need to reimport all the
time).Reading all tutorial sections is a first thing a new user should
do.Second thing is understanding categories.Categories are NOT
folders (like in Windows Explorer)The difference is fundamental.In
the explorer file appears (usually) only once in the giventree leaf.In
the workspace symbol tree given symbol appears multiple times becauseit
appears in every category leaf to which it belongs toeven if this is the
same symbol and only it exists only as singleentity.One symbol
belongs to MANY categories at the same time.For exampleAAPL (Apple
Inc.)will belongto"Stocks" group category"Nasdaq" market
category"Information" sector category"Comp-Computer Mfg" industry
categoryand may alsobelong toseveral watch lists and favorites
categoryALL at the same time.That's why ONE symbol will appear in
many leaves of the symbol tree.Now if you delete the SYMBOL it will of
course disappear from ALL categoriesbecause you have deleted the
SYMBOL.There are two types of categories:1. with mutualy exclusive
membership: groups, markets, sectors/industries - it means that
symbol MUST belong to ONE group ONE market and ONEsector/industry at a
time you can move the symbol from one group/market/sector/industry
to anotherbut you can not remove this assignment - create
"Unassigned" group/market/sector/industryinstead.2. with free
membership: watch lists/favorites/indexes - it means that a
symbol may belong to ANY number (including zero) ofwatch lists (and to
favorite/index category too) In this case you can remove this
assignment by Watch List->RemoveWatch lists are covered in detail
in the User's Guide:<A
href="">http://www.amibroker.com/guide/h_watchlist.html(the
same is available when you press F1 from AmiBroker)Third
thing:if you use "DELETE" button in Symbol->Categoriesit displays
the warning:"This will delete selected symbols FROM THE
DATABASE".Again: it will delete FROM THE DATABASE, not from the
category.Best regards,Tomasz
