VWAP types:

Period Based VWAP
Date Anchored VWAP
Earnings Based VWAP

Additional features common to all VWAP types:

Each of the VWAP types are described below:

Period VWAP

Simple period VWAP which allows preset, as well as custom periods.

Also allows setting a custom session time for reset at specific time of day.

Date VWAP

Date anchored VWAP which does not reset.
VWAP will start from the selected date.

Updates:

Added the ability to set the VWAP's data source.
Fixed an issue where DateVWAP would draw even before the specified anchor date had been reached.
Improved the way VWAP behaves when a new session begins/VWAP resets (no longer draws ugly lines directly to the new price, instead it continues until the new session and ends abruptly).

릴리즈 노트

Rollback previous release due to some issues with imperfect drawing on session changes.
