Jack,
I use Volume Bar charts all the time on a 5 second database.
Any indicator that uses the Avg, Close, High, or Low for the data
source will change the value at the last bar during realtime data
feeds as the values change.
You can use the Open for the data source and the values will not
change during the last bar. It will be effectively be using the
close of the previous bar. However, your indicators will not be real
time, but delayed by a bar. This may be what some people want, but I
like the heads up of how the bar is developing. When the bar is
close to being complete, the probability is much higher that the High
and Low will not change.
The AB program is not designed well enough so that it can predict the
High, Low, and Close of the current bar before the bar closes. Many
people have asked Tomasz to add this feature, but he stubbornly
refuses to enable this capability. I am sure he already has it
implemented for his own personal trading, but selfishly does not want
to share it with the rest of us so that we can all become
billionaires overnight. It makes me mad to be put at such a
disadvantage to other traders, but I will keep working on my AFL
indicators to try to put this feature in on my own --and when I do, I
will share it with everyone free of charge.
(the previous paragraph is meant for entertainment purposes only. Do
not try to trade with data that does not yet exist unless you have
the supernatural ability to see the future.)
Have a great weekend,
Dennis

does VolumeBar only work on tick database? and why are indicators
moving around, what I mean is an EMA crossover signal can disapear
or move when new data coming in.
thanks
