VWAP Anchoring: A Systematic Approach to Intraday Entries

Volume Weighted Average Price (VWAP) is arguably the most important indicator in institutional trading, yet most retail traders use it incorrectly. The standard session VWAP resets daily and provides a useful intraday benchmark, but the real power lies in anchored VWAP — anchoring the calculation to significant events like earnings announcements, FDA decisions, or major support/resistance breaks.

The concept is rooted in behavioral finance: institutions that entered positions around a key event use the average price from that point as their reference. When price returns to their cost basis, they tend to add to winning positions or exit losing ones. This creates predictable zones of supply and demand that repeat across different stocks and timeframes.

Our systematic approach uses three anchored VWAPs simultaneously: the earnings VWAP (anchored to the most recent earnings date), the swing VWAP (anchored to the most recent significant swing low or high), and the event VWAP (anchored to the most recent catalyst like an FDA ruling, product launch, or analyst upgrade/downgrade).
