What this script says

Session VWAP and Profile is an indicator drawn over the price chart.

You can change 2 inputs: `rows` (default 24) and `value_area` (default 70%).

It calculates `session_vwap` as VWAP, `upper_band` as `session_vwap` plus the 20-bar standard deviation of the close and `lower_band` as `session_vwap` minus the 20-bar standard deviation of the close.

On the chart, it plots `session_vwap` as `vwap_line`, plots `upper_band` and `lower_band`, shades between `upper_band` and `lower_band` and draws a volume profile.
