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.
If you are not sure what options to choose, just press "Next" all
the time and you will safely complete the procedure
without changing any settings.
