VWAP Stdev Bands v2 — Indicator by SandroTurriate

vwap

This is an update to my original VWAP Stdev Bands indicator found here:

* Fixed the calculation of the opening bar
* Added two additional deviation bands
* Added horizontal line of previous VWAP close

This update adds support for two more sets of bands, allowing you to show 1st, 2nd, and 3rd deviations. These extra bands are disabled by default as to not crowd the chart, but are shown in the screenshot and can be enabled under the indicator settings. The numbers 3.09 and 1.28 were recommended by coondawg71 in a comment on the original version. The previous version started calculating VWAP on a change of day, instead of a change of session. It now correctly calculates the VWAP when a new session begins. The last addition allows you to plot the previous day's VWAP close. The VWAP is where price has found balance, which makes these levels significant among the noise.

Thanks to coondawg71 for all suggestions.
