Let's make sure we are clear, must VWAP start at 0:00? I cannot get for my software VWAP to start at the opening bell, but it only starts at midnight.
No, not necessary to start at 00:00. I have a system that starts at PST midnight and another that starts at 6:30 PST. (I'm based in California) Basically set off Europe's open and US open. Since you are using Sierra Charts you should be able to get a custom VWAP study made that will start at whatever time you want.
