Maintenance
TJ: can you clarify this one comment you made:
"The ones which are not referenced by any layout
can be deleted from internal table."
I do not remember a choice labeled with "Delete from
Internal Table" vs "Delete from Hard Drive". I got the impression, that
clicking next would delete all checked files from the hard drive. Is
there a way to delete from the table and still leave all AFL files on the
drive, yet relieve the 3000 active indicator limitation?
Can you clarify please.
Thanks,
Ken
Hello,
THe limit is that you can have upto 3000 indicators
actually used at the same time in layouts.
The number of AFL files is UNLIMITED.
Indicator maintenance checks for any indicators that were
deleted from any layouts on your hard disk and frees table from
entries
allocated for indicators that were deleted. This
procedure is rarely but still needed because if you delete indicator from
one
layout there is no guarantee that there is no other layout
file buried somewhere on your hard disk that still references given
indicator.
So Indicator Maintenance scans all hard disks and all
partitions looking for layout files and analysing them to built the
"actually used" table of indicators. The ones which are not
referenced by any layout can be deleted from internal table.
Depending on your choice you may leave default behaviour
(cleaning up only internal table) or deleting actual formula
files
that are not referenced. This is up to you. If you don't use
particular formula for say AA Scan/Backtest/Optimization you
can
delete it. If you use it or need it for some archive
purposes - leave it unchecked.
As for rules to use - the only rule is in AMiBroker - if you
don't know what to do - accept defaults. The same with indicator
maintenance.
Just press "Next" all the time and you will safely complete
the procedure without changing any settings.
Best regards,
Tomasz

Can someone tell
me where the limits on indicators is explained and how the Indicator
Maintenance Wizard works. Actually, I ran it so I know what it does step by
step, but am curious what the "rules" are about its use. For example,
I have a bunch of indicators in Formulas>Custom, with a variety of
subfolders under Formulas, plus I have a large inventory housed in My
Documents. I do not necessarily want to delete any of these, and dont
want to spend the time reviewing each one to see whether I want to keep it
or not. What is the program limit on these (I never thought there was
a program limit), and why is there such a limit?
Any
comments?
Thanks,
Ken
