I have done some thing that might employ similar technology....
If you are interested, I have a basic little ela that plots sine wave arcs
for cycles.
ahhh, half days and holidays.... so much fun. Try keeping track of what your
values should be based on date and time, then plot, draw lines, etc on each
bar. I have price and time stuff that works properly for any holiday, but I
will say that it is not easy to do...the exceptions make the code 3x as long
as it would be w/o holidays.. Unfortunately, all the stuff that I have done
in this arena employs some concepts that I can't share, but I'd be happy to
answer questions. Another thing I will say is this kind of stuff is MUCH
easier in TS8 than older versions.
