VWAP and Market Participant GroupsAlnylam Pharmaceuticals, IncBATS:ALNYMarthaStokesCMT-TechniTraderThe first FACT that you need to understand about VWAP as an indicator that has bands that contract and expand is which of the 15 Market Participant Groups are in control of price. The Market Participant Groups are critical to understanding how to interpret VWAP and how to use Chaikin's Oscillator to reveal the professionals, corporate buybacks, Sell Side Institutions, Hedge Funds, and MEMEs Groups activity before the candles shift from down side to upside or vice versa. This is critical to your success trading stocks, especially intraday trading. One of the most common misunderstandings about VWAP is it DOES NOT reveal Dark Pool activity. Dark Pool activity is not visible on intraday charts as these orders are all executed on the ATS venues. Dark Pools do not trade intraday. Dark Pools do not create surges in volume. Often a Dark Pool Buy Side Institution will go directly to the company and buy shares of stock from the company. This increases the outstanding shares. Corporate buybacks reduce outstanding shares.
