VWAP stands for Volume Weighted Average Price. It is one of the most powerful and popular technical indicators used by intraday (day) traders to determine the true average price of a stock based on both price and trading volume.
While a standard Moving Average only looks at the closing prices, VWAP factors in how many shares were actually traded at each price point. This gives you a much more accurate picture of where the actual market value lies.
The VWAP Formula
Your charting software does this automatically, but it’s helpful to understand the logic behind it:How Traders Use VWAP
Traders look at the VWAP line on their charts as a baseline for market efficiency, using it to gauge momentum and find entry or exit points:
Bullish Bias (Above VWAP): If the stock price is trading above the VWAP line, it means buyers are paying more than the average intraday price. The momentum is upward, and traders generally look for buying (long) opportunities.
Bearish Bias (Below VWAP): If the price is below the VWAP line, the stock is considered to be in a downtrend. Sellers are driving the market, and traders often look to short-sell.
Dynamic Support and Resistance: The VWAP line frequently acts as a psychological magnet. Prices will often pull back to the VWAP line, find support or resistance there, and then bounce off it.
The Institutional Benchmark: Large institutions (like hedge funds or mutual funds) use VWAP to execute massive orders. They consider it a "good deal" to buy below VWAP and sell above VWAP so they don't accidentally disrupt the market price.$NVDAB
Key Limitations to Keep in Mind
Intraday Only: VWAP accumulates data from the opening bell and resets completely at the start of every trading day. It is not meant for swing trading or long-term investing.
Late-Day Lag: Because it calculates cumulative data, the VWAP line becomes less sensitive to price spikes as the trading day goes on. A massive surge of volume at 10:00 AM moves the line easily; that same volume at 3:30 PM barely nudges it.
