I'm using CVB (Constant Volume Bars) for e-mini ES and NQ futures. I need to calculate the velocity of the volume in lots/sec, but I have a problem with the bar time duration when volumes run very fast: as you can see from the attached pictures (highlighted by the ellipses) the bar time duration in some cases became negative and obviously this is not possible. Is it possible to solve this issue? Waiting for your kind reply. Best regars Pierpaolo Savi |

There is no need to say thank you. It creates more burden for us.

The problem of negative bar time duration was still present on ES e-mini future, but until today, just around at the end of the close of trading day (21:00 London time zone), so it didn't disturb. Today the negative bar time duation was measured at 17:51:31, so during the trading day. Below the chart. http://www.sierrachart.com/image.php?Image=1493667620588.png Waiting for your kind reply.

Not sure if related, but when using tick-bars (Number of trades per bar setting) i do see sometimes negative values in the Countdown Timer study. This is on build 1543.

A negative number of trades remaining? This is unrelated. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

I didn't notice negative number of trades remaining. What I see is just a negative value when I divide the volume by bar time duration. |

In regards to post #10, the calculations are done correctly. Not sure why there would still be a negative value in some cases, but a negative value is now set to 0 in case that happens. This will be out in the next release. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users. Try to keep your questions brief and to the point.

I use Bar Time Duration as denominator of the Study Subgraphs Ratio (volume/bar time duration), so I kindly ask you to consider this (perhaps it can be set a value close to 0 but not 0). Best regards. Date Time Of Last Edit: 2017-05-02 08:12:53

You will need to solve this on your side. That is not something we are going to do. You can always modify the study as well to meet your requirements.
