Please, please,
No more " Are you really,
really, really sure? " windows or BS boxes.
Tell me how a professional IT developer loads/saves the wrong
formula when the name of the formula is clearly listed in the OPEN/SAVE
AS dialog boxes.
While I agree that it would be nice if AB would
automatically load the name of the open formula from the Indicator Name list
into the File Name part of the OPEN/SAVE AS dialog box, I have no problems
keeping my 400+ formulas straight.

Subject: [amibroker] Indicator
Maintenance
Having just corrupted some of my indicators yet again I
thought I would postsome personal observations and suggested improvements
on AB indicatormaintenance. I am posting here rather than direct to the AB
suggestions boxto get the POV of other users. Hopefully others may be able
to offer sometips on best practice or point out the error of my ways and
also if enoughusers chime in we can then compile a list of agreed
suggestions for TJ toconsider.OK here are my
observations:-It is *far* too easy to corrupt indicators without even
realising it. I betnearly everyone has done this. For those who think you
have never done ittry checking thru the code of all your custom and
builtin indicators and seeif they contain what you expect ;-)In
the early days of AB when we only had slots for a few custom indicators(20
was it?) maintenance was not a problem. But with large and
increasingnumbers of indicators I find accurate maintenance a real
problem. Inaddition we have systems, explorations, scans, filters and
those which docombinations. Over time I have tried various methods of file
suffixes,prefixes, directories etc. to try and keep things under control
but neverbeen entirely happy with it. My feeling is there must be a better
moreorganised solution with maybe separate directories for these specified
viaPreferences.One of the big problems I have is indicators
getting out of sync with thecorresponding .afl file on disk. For example
it is very easy to make anamendment to an indicator while testing visually
via charts/guru commentaryand forget to save to the correct afl file on
disk. Later when I come tosystem test and copy/paste the code into test
afl from disk I get unexpectedresults. BTW I am sure the endless
copy/edit/paste operations will eventallydrive me to complete baldness -
my background is in commericial IT systemsdevelopment so it goes very much
against the grain when you cannot define aformula/module just once and
then just refrence it wherever required. TJhas said he will add this
facility but will I have any hair left by then ;^)Suggested
improvements:-In IB add a Copy button to enable a new version of an
indictaor to becreated quickly. Default new name = old name with numeric
suffice e.g.HolyGrail[2]In indicator browse list add columns for
date and time last modified. Allowsorting on name column or date and time.
At present you cannot check datesor easily determine which indciators you
were last working on.In indicator browse list add columns for In quick
list, Uses builtin code,Use formula only. At present you must laboriously
click down thru every listitem to determine these.Provide some
protection or warning to prevent unintentional overwriting whenusing
Load.IMO indicators should be directly related by filename to the
correspondingdisk file. For example the indicator HolyGrail7 is defined
via the disk fileHolyGrail7.afl Ideally AB preferences would specify the
directory name(s)for custom and standard indicators. This would prevent
many maintenanceproblems that the current architecture invites and would
also facilitatemany other maintance operations (see
below).Facility to bulk load indicators from disk files into AB. i.e.
browse andselect multiple .afl disk files which are then loaded into
correspondingcustom or builtin indicator names.Facility to bulk
copy indicators from AB to disk files i.e. browse andselect multiple
AB indictors which are then copied to selected
windowsdirectory.Allow the default directories for custom and
bulitin indicators to bespecified via Preferences. Maybe also systems,
explorations, scans....?All POVs
