PpSignal Multi-Day VWAP

Thank to @mortdiggiddy
original script:

Chart the multi-day Volume Weighted Average Price ( VWAP ). Normally, the VWAP is tracked for the current day, from the first bar of the day (regular or extended session). The VWAP shows the current value of:

-> sum(hlc3 * volume , barsForDay) / sum( volume , barsForDay),

-> where 'barsForDay' is the total number bars that have elapsed during the day for the chart interval.

The multi-day version tracks the VWAP for N days back, by averaging the previous N - 1 day bars VWAP and the current VWAP for the current bar (chart interval).

This is very different that simply using a volume weighted moving average , since the closing VWAP values are used for the historical day bars. The results are interesting for intraday trades... especially for values of 1, 2, 3, 4, 5 ....to 21 days.

Release Notes:

we changed internal calculation.
You can use this indicator with ppsignal candle converter, the best signal is when the candle converter changed the tren and vwaw changed the trend too...see the picture.
