<FONT face=Arial
size=2>Herman,
I am quite surprised with
this post, especially:
<FONT face=Arial
color=#0000ff>
<FONT face=Arial color=#0000ff
size=2>> you cannot run your backtester on composites,
Why do you
think so ?
<FONT face=Arial
color=#0000ff>
<FONT face=Arial color=#0000ff
size=2>> you cannot display standard charts on composites, etc.
Why do you
think so ?
<FONT face=Arial color=#0000ff

Hope this helps.

to the Database
<FONT face=Arial color=#0000ff
size=2>The easiest way is to copy your custom arrays to a Composite
(see AddToComposite() and the tutorial on the AB website). You can recall
(read back) the contents of a Composite file with the Foreign(). Composites
are saved on your hard disk in the Data (default) directory; they stay
there until you delete them.

<FONT face=Arial color=#0000ff
size=2>Alternatively you could use the Osaka plugin and create tables with
your custom data, these tables are also stored on your hard disk and can be
read/written to at will.
<FONT face=Arial color=#0000ff

<FONT face=Arial color=#0000ff
size=2>Since your data is probably updated each day you will have to
recalculate you custom arrays daily. However, you could work around
this by using inline composite creation - but this has other
complications.
<FONT face=Arial color=#0000ff
size=2>The only drawback with composites is that you cannot do everything
on them
like you can with price arrays, for example you cannot create a composite
based on composites, you cannot run your backtester on composites, you cannot
display standard charts on composites, etc. This is a serious limitation
however I get around that by omitting (against the AB rules) the leading "~"
of composites names. I have only tried this a few times so you have to
experiment to see whether all I am saying in this paragraph is correct -
experimentation is what makes you really get the most out of
AB.

Writing Arrays to the DatabaseAll,Let me
try asking again. I calculate several arrays in a custom indicator
that I want to makea watchlist out of so I can do Automatic Analysis on
them and use the results screen to display multiple variables. Can I
dothis by writing the arrays to the local database? Or do I have to do
the time consuming calculations in the AA window itself?If this
isn't a good approach, can anyone suggest other approaches that I might
take?ThanksBillSend BUG REPORTS
