// The idea is to first find the Daily 7-bar ATR (or any other nr. of days desired) 
// and then input that into the range, i.e. of the 7-Day ATR is 2.5, input 2.5). The factor input 
// determines the width of the bars relative to the ATR and since there are six bands, one sixth 
// of the Daily ATR would be .1666, so I changed that to .1618 to have a nice Fibonacci number. 
// In any case, the result is that the range of the bands from the outermost on top to the outermost
// on the bottom should roughly correlate with the Daily ATR. Ideally these bands could
// be rounded to ticks so that they will print out precise price levels for trading but
// I am not able to program that in in this language. 
// For use of vwap, use google etc. I prefer it to moving averages since it is a precise statistical 
// calculation using volume, and also it remains the same in all time frames, albeit mainly
// used for intraday charts.
// I also like to use the bands for entries, stops and profit targets - along with basic 
// price information from the bars.
// I wrote essentially the same indicator called VBandPts wherein the input for the bandwidth
// is a simple point value number so that you can get the bands to display in ticks or points,
// i.e. 3 points, 2.5 pts etc. So in that case you can take the current indicator to see
// roughly what the bandwith is, and then use the VwapPts on the chart to get bands 
// close in value to the raw calcs from this one, but more helpful for trading.
// Either way, it's just a simple visual grid overlaid on top of the basic vwap value.
