Hi Mike,
I've now been using the Anchored VWAP indicator for the past 2+ weeks and have come to the following conclusion. I believe having manual start and end identifier lines is redundant and unnecessary. Because this function uses the draw function to draw manual lines they always remain on the chart, and any linked charts, even if hidden. These have to be continually removed otherwise you wind up with scores of vertical lines on your charts. The use of "Custom Dates" for start and end times is far better, you can choose to use "Live Update" or not, and accomplishes the same thing without lines being displayed or hidden all over your charts. There is no need for vertical lines to drawn either when using "Custom Dates" as this creates the same problem of having scores of vertical lines lurking on your charts.
Best regards,
Scott
