Re: Reply to post 'Intraday Advance/Decline Line?'
Thanks all,
I believe that the solution is pretty simple and maybe the confusion
here is between cumulative and ratio based a/d lines.
ratio is dead simple, it really is adv/decl issues and is certainly a
valuable indicator.
cumulative is just that though, a cumulative running total (over n
periods, usually 10 or 21 day, but could be any period) of $add (for
NYSE) with the current day value added to the result.
to build it one would do something like get the running cumulative
total of $add over n periods prior to current close --
close(n,1,"$add") -- where n is iterated for whatever number of days
chosen and then add the current day closing value to it.
here is a link showing what the line is going to look like when plotted.
the indicator is generally used over periods of days, not intraday to
get a sense of the longer term trend and help identify divergences in
price/breadth. make sense?
i'm afraid i'm just hopelessly bad with efs as Alexis can attest to and
i'm sure this is not a big deal to do. just beyond my feeble abilities.
