Hello,
These fields are mainly for READING from AFL.
If you want to write to them you need new composite ticker
(AddToComposite() function).
With regards to writing to "current" ticker - my previous response was
not entirely correct
- composites won't add to themselves, otherwise the composite would be
sum of itself and the rest,
so internally AmiBroker has a protection against composite onto itself.
It is not specific to
aux fields, it won't allow you to do that using OHLC too.
You need to use *different* symbol as a writing location than the one
that is currently being
processed.
Generally price data (including aux fields) should not be written from
AFL (with exception to composites).
These fields are designed to be either imported using ASCII importer or
fed via plugin.
Primary "by design" purpose of those fields are to store Bid and Ask for
real time plugins and
unadjusted close for EOD plugins. There can be other uses hence
'general' name given to these fields,
but in general, they are not "user" fields, but rather "auxilliary
price" fields.
Best regards,
Tomasz Janeczko

Does anybody use AUX1 and AUX2 fields from AFL?
How to assign values to these fields of original symbol from AFL
directly? Is it possible?

Hello Tomasz.
I am trying to use new AmiBroker 5.30 with my data and have
difficulties with AUX1 and AUX2 fields.
I have local 1 hour DB (no plugins, just ASCII imported). And I am
trying to assing AUX1 value. I am running Scan for all symbols with
following code (Code just composed from your examples):
SetBarsRequired(sbrAll, sbrAll);
buy = 0;
tst = 123;
AddToComposite(tst, "1_"+Name(), "1", atcFlagResetValues);
AddToComposite(tst, Name(), "1", atcFlagResetValues);
As result I got 1_XXX symbols with AUX1 equal to 123 - this is
correct. But value AUX1 for initial symbols XXX are still 0.
From you mail (see below) I understood that last line (for Name())
also have to work. But it isn't :( What I do wrong?
Thank you in advance.
BR, Vlad
