John,
One of the things that I do is to have a dedicated sheet in AB
just for development. TEST in this case.
<IMG alt="" hspace=0 src="png00063.png"
align=baseline border=0>
I ALWAYS know that whatever I was working on last was there,
and all the formula names there are preceded by "TEST-", so they will all show
up together in the IB list box.
When I decide to move on to something else, I remove the TEST
prefix from the name and rename it.
I'm not sure what your methodology is to edit and change
formulas, but I can do it without hitting APPLY, and the changes are set by
just clicking on some other formula in the IB list. I've done it hundreds of
times, all the time.
I don't always save every little change to every formula to
disk in the AFL directory. Just what I feel are major changes and upgrades.
I do save the broker.charts file often. That way, all the
custom formulas in IB are all collectively saved at once and in one
movement.
I think that your wheels fall off when you use LOAD to find
your files. Remember that AB's editor works on what is in the broker.charts
file, not what YOU saved to the AFL directory. The MODIFIED list in
LOAD won't show you what the last edited file was. It will only show you what
was the last file that you saved to the AFL directory was. The last edited
formula is in the broker.charts file.
I use the AFL directory as just a long-term disk archive
anyway. If you want to directly edit something saved in your AFL directory, use
notepad or something like that without going through AB.
P.S: Yes, I'm really, really, really sure since I had to
rebuild my broker.charts file about 6 months ago when I exceeded the dreaded
"file name length" rule. Since then, I make sure of what I'm doing when in the
AB editor.

IB and scroll thru indicator listsearching for that indicator I was

search for required AFL file on disk usingfile details date last modified
etc. I make the mistake of Opening therequired indicator file and doing
something with it without having firstremembered to reposition the IB
scroll list on correct entry (or new entry)thereby overwriting IB
indicator code. The Load dialogue obscures most ofthe IB dialogue so there
is no easily visible reminder of the IB indicatorentry the program is

(really, really sure)that all your IB code matches that in your .afl

PM Subject: [amibroker] Indicator Maintenance
Having just corrupted some of my indicators yet again I thought I
wouldpost some personal observations and suggested improvements
on AB indicator maintenance. I am posting here rather than direct to
the AB suggestionsbox to get the POV of other users. Hopefully
others may be able to offer some tips on best practice or point out
the error of my ways and also if enough users chime in we can then
compile a list of agreed suggestions for TJ to
consider. OK here are my observations:- It is
*far* too easy to corrupt indicators without even realising it.
Ibet nearly everyone has done this. For those who think you have
never done it try checking thru the code of all your custom and
builtin indicators andsee if 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 increasing numbers of indicators I find accurate
maintenance a real problem. In addition we have systems,
explorations, scans, filters and those which do combinations. Over
time I have tried various methods of file suffixes, prefixes,
directories etc. to try and keep things under control but never been
entirely happy with it. My feeling is there must be a better more
organised solution with maybe separate directories for these specified
via Preferences. One of the big problems I have is
indicators getting out of sync with the corresponding .afl file on
disk. For example it is very easy to make an amendment to an
indicator while testing visually via charts/gurucommentary and
forget to save to the correct afl file on disk. Later when I come to
system test and copy/paste the code into test afl from disk I
getunexpected results. BTW I am sure the endless copy/edit/paste
operations willeventally drive me to complete baldness - my
background is in commericial IT systems development so it goes very
much against the grain when you cannot definea formula/module
just once and then just refrence it wherever required. TJ has
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 be created
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.Allow sorting on name column or date and
time. At present you cannot check dates or 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 everylist item
to determine these. Provide some protection or warning to
prevent unintentional overwritingwhen using Load.
IMO indicators should be directly related by filename to the
corresponding disk file. For example the indicator HolyGrail7 is
defined via the diskfile HolyGrail7.afl Ideally AB preferences
would specify the directory name(s) for custom and standard
indicators. This would prevent many maintenance problems that the
current architecture invites and would also facilitate many other
maintance operations (see below). Facility to bulk load
indicators from disk files into AB. i.e. browse and select multiple
.afl disk files which are then loaded into corresponding custom or
builtin indicator names. Facility to bulk copy indicators from
AB to disk files i.e. browse and select multiple AB indictors
which are then copied to selected windows directory.
Allow the default directories for custom and bulitin indicators to
be specified via Preferences. Maybe also systems, explorations,
scans....? All POVs welcome.
