VAMA Volume Adjusted Moving Average Bands

This indicator is standard deviation bands using a live analysis adaptation of Richard Arms' ‎Volume Adjusted Moving Average as their basis. ‎VAMA utilizes a period length that is based on ‎volume increments rather than time.

• SampleN - N ‎volume bars used as sample to calculate average ‎volume , 0 equals all bars.

VAMA Source - Price used for ‎volume weighted calculations.

VAMA Length - Specified number of ‎volume ratio buckets to be reached.

VAMA VI Fct - Size of ‎volume ratio buckets.

VAMA Strict - Must meet desired ‎volume requirements, even if number of bars has to exceed ‎VAMA Length to do it.

• STDV Factor - Standard Deviation multiplier.

• STDV Length - Standard Deviation period.

• Brightness - Color opaqueness for the band fills.

Please see previous published example here for more details on VAMA's usage and inability to redraw the past on time based charts.
