Use Case
Anchored VWAP lets you place a VWAP starting from any significant market event, creating a precise institutional reference level with standard deviation bands above and below.
Strategy
Anchor the VWAP to a major swing low or high. Use the VWAP line as dynamic support in an uptrend: buy when price pulls back to the anchored VWAP with a bullish confirmation candle. Use the upper band as a target.
Common Mistakes
Do not anchor VWAP to an arbitrary point. Avoid treating Anchored VWAP as a static support level. Do not use it without understanding which anchor point is institutionally significant for your instrument.
