Thanks much Clyde, I've been wanting something like this for a
while. Is there a modification that can be made to force the boxes
to consistently start at the beginning of each new date on an
intraday chart? For example, on a 5 min time frame, with NBars set
to 3 (i.e., attempting to encapsulate three 5 min bars in order to
represent a 15 min bar), occasionally the last one or two 5 min bars
from the prior date will be used as the first, or first and second,
of the three bars used to generate the first box for a given date and
this will result in all the subsequent boxes being incorrectly
shifted so that it can be seen that the boxes don't match up with
actual 15 min bars plotted as data2. The boxes periodically regain
and then lose their proper shifting over the course of time (days).
The problem is due to the data on multiple days not being perfectly
consistent (and so the "Shift" input doesn't help in this regard) ,
and not with your indicator per se. I've tried a number of different
things without success. It seems as if one possibility could be to
use a second MOD function with CURRENTTIME to force the boxes to
begin at precise time intervals, but I haven't been able to make it
work (e.g., Mod(CurrentTime,0015) = 0 in the case of 15 min bars). I
couldn't get anything using Date > Date[1] to work either.
Thanks,
Mark
