Bad behaviour of volume on charts based on seconds data
Posted: Oct 14 2011
I've reported this issue in this post on the PM section
http://www.multicharts.com/pm/viewissue ... _no=MC-658
I've find a bug in MC 7.0.4510.400 official release about volume calculation on charts based on "seconds" data.
I've coded a very simple code about Volume Acceleration which sums the volume of the last N seconds but it gives me always too big values even when the market is very slow and poor of volume. I've plotted the same indicator on a 1 minute chart and set the same time lap (5 minutes or 300 seoncds). The indicator always gives me 2 different values. How could it be ?
This is the code of Volume acceleration plotted on a 1 second chart (300 seconds LapTime) or on a 1 minute chart ( 5 minutes LapTime):
it's the same if you use ticks instead of "volume" with checked "build volume on "tade volume"
This is the picture of my chart

How could it be those differences ?
Please make a deep control on Volume calculation about charts with differents resolution.
The indicator plotted different values and it's not possible on the same Time Lap. How could it be ?
The volume calculation gives high values even during poor periods of volume and this demonstrate a BUG on the volume calculation.
Please check it.
Thanks

Code: Select all
Code:
Inputs:
laptime(300);
value1 = summation(volume,laptime);
Plot1(value1, "VolumeAcceleration");
