does the rolling vwap study exclude periods of no trading? i.e. holidays the output of the study around the xmas and new years holidays seems to be calculating incorrectly and including the dec25 and jan1 calendar days into the calculations. thanks Date Time Of Last Edit: 2016-01-10 15:50:46

the output of the study around the xmas and new years holidays seems to be calculating incorrectly and including the dec25 and jan1 calendar days into the calculations. Yes those days would be included in the calculation even if there was no trading/data. The code does skip Saturday and Sunday. But overall the logic of how this is implemented is not really the best. We will have a look at this. 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 see in the post below you changed the rolling vwap methodology but now it is not a continuous rolling? not sure of the logic behind using that method, rolling to me would imply a continuous value like a moving average dropping old and adding new etc...can I get the code for the previous version so can still use? thanks Rolling VWAP
