Have
you examined those files in your different installations and found them
meaningfully different?

Installations
Hi
Bob,
How
about Broker.Sectors and Broker.Industries Broker.Params ... these
are all in the program directory ... do they not cause interference when
only one installation is used for all databases, since every instance will
have to start at same database and then be shifted to another one (if so
desired).
Also
another point came up ... Is there an advantage, either way, for access to
CPU capacity?
In
a multithreaded CPU, AB is allowed a maximum of 50% of CPU
capacity.
Can
a second instance of same installation access the other 50% of CPU
capacity as well as a separate installation??? or are both limited to same
50% ???

RE: [amibroker] Multiple AB Installations
Ara,
The
DB-specific info is in
broker.layout, broker.master, broker.watch, and
broker.workspace.
All
four reside in the individual
DBs.

Graham,
Thanks
for the detailed note below...
I
read through the section on broker.* files and what they
contain.
There
seems to be a fair amount of potential for interference between instances
from same installation depending on how one uses the system. For
my purposes having one set of Broker.* files would mess things up ... so I
have to stick to multiple installations.
With
TJ solution of disabling autosave, things should be OK, but I do hope
he modifies the autosave as it is a very good feature to
have.

Re: [amibroker] Multiple AB Installations
I
have many databases for different markets and timeframes and have always
run 2 instances during the trading day, intraday and end of day databases.
Plus I often move to different databases as I do work on different AFL.
I
did use 2 installations a long time ago but have found one installation
running multiple instances is easier and better.
I
have occasionally run afoul of the layouts not being saved properly,
but to be honest this is such a small inconvenience to re-insert any AFL
charts that you added before.
Recent changes occuring make the saving
of layouts better from memory as they will auot save to your named layout
when exiting that database, correct me if I am worng.
I
would say I am a far heavier user the the majority of users as my work of
writing AFL takes me to many different exchanges and time bases ( some of
these are end of day and intraday of ASX, US, forex and futures exchanges)
I keep all of these in separate databses so that I can concentrate on
using the data rather than worrying over same symbols overwriting. I also
have many different layouts for each database to isolate the various jobs
I do as I do not want 100's of sheets for each window finding 10 to be
more than sufficient for organising the charts.
I
say all this to just point out that a single installation works well with
very minor inconveniences.
I
would also point out that you get into the habit of saving your layouts as
named layouts, and like all software get into the habit of saving these as
you make changes. They can easily then be brought back to the living
display as required.

Two

shared registry settings].

Graham,
I
would prefer to have a single installation and use it with multple data
bases as you suggest... however I ran into problems earlier doing
that. That was some time ago that I had to switch to multiple databases...
perhaps before certain changes were made that make the operation of a
single installation using multiple instances practiclal.
I
know that many changes have been made over time to the preferences and
parameters controlling each data base setting have been moved to the
individual data base. The problem earlier was that parameters relating to
databases were common and part of preferences, thus all databases had one
set of parameters (such as number of bars)... which was a pain...
Also
I beleive that even with current version, a single installation would have
a single set of symbols. Broker files reflecting a unique set of setting
for a particular application (EOD, Real Time etc). Is that nor correct?
Do
you (or anyone else) currently use a single installation with multiple
instances without any complications???
Thanks

Re: [amibroker] Multiple AB Installations
Why
do you need multiple installations of AB on one computer
You
can just have the one installation and use different databases. AB can be
opened many times from one installation and have separate database for
each occurence.

[amibroker] Multiple AB Installations
I
am having problems with multpile installations getting mixed
up.
When
I open one installation, I find the layout from another installation have
been copied into it.
Example:
1.
Open Tick data base and see layouts from Time (1 min) or EOD data
base.
2.
I run scripts via OLE on EOD data base, and results show up in RT
installation.
How
can we keep these from crossing over?
(I
think there was a recent related discussion, but can not find
it)
