//
// This plot takes a simple 60 bar window
// For each bar in the window 3 things are plotted:
// 1.) The volume-weighted average, each bar's volumne * price summed, then divided by total volume
// 2.) The simple 60 bar average (not weighted)
// 3.) The close price (for reference)
//
// Green is used when the weighted price is above the average
// This is meant to indicate that actually, by volume the stock may be worth more that it is currently trading at.
// I made a new script was because I didn't see one that had a rolling hour window.
