Subject: Re: [amibroker] Re: I think the real defect of Amibroker is
charting
There are a number of other charting suggestions than the three that you
mention, including some that have been implemented completely or to some
degree. Some are totally new and others address improvements to tools, ease
of operation, appearance, etc.
Different users will zero in on different "make or break" characteristics
that move them to other software where they perceive better performance and
use AB where it is superior. It would be nice to have one program that does
all but at this point some feel that more than one is needed. Nothing wrong
with that. Some software outfits strive to be the one that fits all while
others aim to be the tops in a specific niche. Users will figure out which
one or combination works best for them - and that's OK.
Charting suggestions are not new and have been made through the years even
before the new board existed. I suspect that some are "lost" on the current
board because of the way they are described either in the title or lack of
clarity in the message. Perhaps the suggestion board (and maybe also the
bug board) needs subsections for charting, AFL, etc. to ensure that
suggestions are properly grouped. If this were established then users could
move or copy previous suggestions into the appropriate sub-board and future
suggestions would automatically be properly classified.
