This is a simple trend identification script which is based on the current vwap (Cvwap) and previous vwap (Pvwap).
Pvwap in the sense; previous day vwap closing value.
Bullish: price is closing above the current day vwap and previous day vwap(pvwap). Bearish : Price is closing below the current day vwap and previous day vwap (pvwap).
Made a change to the barcolors as well :)
Bullish Green Bar: close is above Pvwap and Cvwap. Blue bar: close is above Pvwap but below Cwap.
Bearish Red bar: close is below Pvwap and Cvwap. Purple bar: close is below Pvwap but above Cvwap.
