OBV vs VWAP: Which Indicator Is More Reliable?
Both On Balance Volume (OBV) and Volume Weighted Average Price (VWAP) are volume-based indicators, but they serve very different purposes. If you’re unsure which to trust for trend confirmation or entries, this guide on OBV vs VWAP will help you choose the right one for your trading needs.
What Is OBV?
OBV (On Balance Volume) is a cumulative momentum indicator that tracks volume flow. It adds volume on up days and subtracts it on down days, creating a line that reflects buying or selling pressure over time.
Key uses:
- Spot divergences between volume and price
- Confirm trend strength
- Identify potential breakouts or reversals
What Is VWAP?
VWAP (Volume Weighted Average Price) calculates the average price of a stock based on volume. It resets each day and shows where most trading activity occurred, making it especially useful for intraday trading.
Key uses:
- Acts as dynamic support/resistance
- Helps gauge fair value
- Commonly used by institutions and algo traders
