Could you please confirm for me what calculation is being used in the NT8 default order flows vwap indicator to calculate standard deviation bands?
I recently tried it alongside several other established vwap indicators, and the bands often don't line up. I realise that vwap values will vary a little with data resolution, but I apply these all on a 1 minute chart which all are using for their calls and the vwaps align, but the sd bands often do not. I tried with my own interpretation of the way to calculate standard deviation also, and that provides a different result to nt8 vwap too. Example below.
Just trying to determine which ones are valid as in some cases, per the attached which has 2 vwap indicators with a single 1 sd band. You can see they can get quite out of sync in volatility on occasion. Almost 10 nq points here. Thanks.
