Innovation is rare in technical analysis as the field has been worked intensively for a long time and the low hanging fruit is long gone. I first came across Volume Weighted Average Price, VWAP as it is known, many years ago as a trading technique for large orders used mostly by institutions. More recently it has surfaced as an analytical technique, Anchored VWAP. To my mind that is a real innovation and Brian Shannon is the analyst to tell you what it is and how to use it.
