<FONT face=Arial

<FONT
face=Arial>
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.

Subject: RE: [amibroker] Writing Arrays
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>
<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
size=2>
<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
