I see,
that is how to import different exchanges and keep them
separate.

Am I
able to do scans etc on these diferent directories at the same time or must I
scan data from one of the databases, and then open anotyer dtabase before
running a scan on that data?

Why don't you create different databases for
diferent exchanges or did you?

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 Message-----From: Tomasz

was: Re: [amibroker] Importing datainto 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
