VWAP Bands, which stand for Volume Weighted Average Price Bands, are an extension of the basic VWAP metric. They are designed to provide additional insights into price trends by capturing volatility and helping identify potential support and resistance levels. Here’s how you can use VWAP Bands and decide on the standard deviation to apply:
Understanding VWAP Bands: VWAP Bands are constructed by calculating a VWAP line (the average price a security has traded at throughout the day, based on both volume and price) and then adding and subtracting standard deviations from this line. The result is a series of bands above and below the VWAP, which can serve as benchmarks for potential price reversals or continuations.
Setting Standard Deviations: The standard deviation in VWAP Bands is a measure of price volatility. Common default settings include one and two standard deviations, but the choice can vary depending on your trading strategy and the security being traded. Here’s a guide:
One Standard Deviation: This setting is typically used for a narrower market, capturing about 68% of price action. It’s useful for identifying tighter support/resistance and is best in less volatile markets.
Two Standard Deviations: Capturing roughly 95% of price action, this setting is more suited for volatile markets or when you are looking for more significant market movements before identifying a potential reversal.
Application in Trading:
Identifying Trends: VWAP Bands can help confirm trend strength. In an uptrend, prices generally stay above the VWAP line, often finding support at the lower bands.
Detecting Reversals: Prices moving outside the top or bottom bands may signal exhaustion, potentially leading to a reversal, especially when coupled with other indicators.
Support and Resistance: The bands themselves act as dynamic support and resistance levels. Traders often look for reactions at these bands to make trading decisions.
Strategy Integration: Integrating VWAP Bands into a trading strategy involves careful observation of price interaction with the bands along with other technical indicators like RSI or MACD. This integration helps in making more informed decisions regarding entry and exit points.
By using VWAP Bands with an appropriate standard deviation setting, traders can benefit from a clearer understanding of market dynamics, aiding in effective decision-making processes. Always backtest your settings and strategies to align them with your specific trading style and risk management rules.
