Hi Support,

I am using IBar.getVolume() on both Ask/Bid side to get volume for a indicator.

On Bar Chart there is no problem about volume information between chart and indicator.

But on Tick chart, It is found the Tick's Ask/Bid Volume displayed is different from what indicator gets.

Sometimes, there has a big difference. Why there is a difference between the data?

The difference is also existed on "Ask and bid volume indicator" by chrizz. https://www.dukascopy.com/swiss/english/forex/jforex/forum/viewtopic.php?f=6&t=24332

A screenshot attached for "Ask and bid volume indicator". It's checked there is no alignment problem for the indicator.

Why there are 2 set of volume data for one chart? And which one is correct?

Thanks a lot!

Indicators on tick chart assume time period of 1 second. Hence, there might be multiple ticks within the 1 sec period and there might be none (as you see in the places where there is no volume bar - there are no ticks within that period)
