Hello,
Of course the field WILL contain any value you put into it...
BUT your changes will NOT be saved until you set dirty flag.
ab = createobject("broker.Application");
target = ab.Stocks(name());
qts = target.Quotations;
AA = AB.Analysis;
AA.ApplyTo = 2;
for(i = 0; i < Barcount; i++)
{
qt = qts.Item(i);
qt.OpenInt = Ranking[i];
}
target.IsDirty = True; /// MUST SET
buy = sell = 0;
Best regards,

Tomasz:
Figured out the (now) simple looking commands to use the Watchlist.
Ranking = C; // replace this with something you want to store
ab = createobject("broker.Application");
target = ab.Stocks(name());
qts = target.Quotations;
AA = AB.Analysis;
AA.ApplyTo = 2;
for(i = 0; i < Barcount; i++)
{
qt = qts.Item(i);
qt.OpenInt = Ranking[i];
}
buy = sell = 0;
I would still be interested to know what happens to Amibroker operation if
the IsDirty Flag is NOT set, if the OI field now contains a value put there by
this OLE code.
Secondly, I can "clear" the value by changing the Ranking value to 0 in the
first line above. This inserts a zero. Does this mean the symbol is still
"Dirty"?

Ah, Tomasz:
Couldn't you have also tossed in the few statements I need to make it work
with a Watchlist. And where do you put the target.IsDirty = True statement.
And what do you do when you remove the value from the OI field? And what
happens if you forgot (or never knew) to set the IsDirty Flag to True? What
happens to program operation when that symbol is used by some other code?
Thanks for adding some more information.
Ken

Hello,
You need to know that AB caches data.
If you are writing directly to quote array thru OLE you need to
set "IsDirty" flag, after you are done with writing to given symbol.
target.IsDirty = True;

Paul:
Sorry to bother you again.
I have proven that your small COM object code stuck at the end of a very
complex AFL will successfully stuff the one parameter I want to save into the
OI field. Yea!
But, is a scan supposed to work on all symbols within a Watchlist? I tried
to run the code (scan) against a three symbol watchlist but it did not work
(only updated the current symbol).
I see there is an Analysis object Analysis.ApplyTo and there is something
called a SCAN Method, but by trial and error, I can not come up with a
statement(s) that works.
Would you be so kind to show me the statement(s) that need to be added so
that I can run through the symbols in a watchlist, and stick the "Ranking"
variable into the OI field of each one of them?
It would get me so very close to a major milestone in my quest.
Thank you so much.
Ken

Ken
I presume you are using the latest version of AB.
I have just tried it myself and I have come back with a COM object error
run it in previous version and is working fine.
Can you try it on an old version of AB, if you have the same result. It is
time to call on Tomasz to fix it.

Paul:
I tried the code you shared below to see if I could stick the
"Ranking=C" value into the OI filed of a single symbol, and I got
nothing. I ran Scan over a short date range, clicked "Refresh All",
and then looked in the Quote Editor for the change, but none was there.
What needs to be done to make this work?
Can the COM OBJECT application be put onto the end of an AFL file
(which generates the Ranking value), and still be expected to work?
Need help. Thanks for any suggestions.
