The Bid-Ask Volume Ratio Indicator is a powerful tool that unveils the dynamic relationship between buying and selling pressures in the market. This indicator calculates the ratio of trading volume occurring at or above the ask price to the volume happening at or below the bid price. To generate a meaningful plot on your chart, a few key conditions must be satisfied:
- Bid and ask prices are distinct, ensuring that there is an active bid-ask spread.
- The bid price remains lower than or equal to the ask price, reflecting the market’s natural order.
- Crucially, neither the bid nor the ask volume can be zero, indicating active participation in the market.
Once these conditions are met, the Bid-Ask Volume Ratio Indicator paints a clear picture of the market dynamics by generating a separate sub chart alongside your primary data series. This insightful indicator provides traders with valuable information on the balance of supply and demand, aiding in informed trading decisions.

Components and Calculation
- Volume at or Above Ask: This represents the trading volume associated with transactions executed at prices equal to or higher than the ask price. It reflects buying pressure in the market, indicating the willingness of traders to pay higher prices.
- Volume at or Below Bid: This component accounts for the volume traded at prices equal to or lower than the bid price, reflecting selling pressure. It represents the willingness of traders to accept lower prices.
Conditions for Plotting
- Distinct Bid and Ask Prices: The bid and ask prices should not be equal. This condition ensures that there is an active bid-ask spread in the market. An active spread is crucial for the indicator to function effectively as it represents the difference between the highest price a buyer is willing to pay (bid) and the lowest price a seller is willing to accept (ask).
- Bid Price Lower or Equal to Ask Price: The bid price must be equal to or less than the ask price. This condition reflects the standard order flow in the market, where buyers are willing to purchase at or below the current market price, and sellers are willing to sell at or above it. It’s a fundamental requirement to maintain the integrity of the indicator.
- Non-Zero Bid and Ask Volumes: Neither the bid volume nor the ask volume should be zero. This condition ensures that there is active participation in the market. In other words, trades are occurring at both the bid and ask prices, indicating market activity.

Interpreting the Indicator
- Market Sentiment: The primary use of this indicator is to gauge market sentiment. A ratio greater than 1 suggests more buying pressure in the market, indicating bullish sentiment. Conversely, a ratio less than 1 implies more selling pressure, signaling bearish sentiment. Traders can use this information to align their positions with the prevailing sentiment.
- Trend Reversal Signals: Significant divergences between the Bid-Ask Volume Ratio and the price chart can serve as potential signals for trend reversals. For instance, if prices are rising while the ratio is falling, it may indicate weakening bullish momentum and a potential trend reversal. Conversely, rising ratios during a downtrend may signal a weakening bearish trend.
- Confirmation of Trends: The indicator can also confirm the strength of existing trends. In an uptrend, a consistently high Bid-Ask Volume Ratio can validate the upward movement, indicating strong buying interest. Conversely, a declining ratio in a downtrend may confirm the bearish trend, suggesting continued selling pressure.
- Overbought and Oversold Conditions: Extreme values of the Bid-Ask Volume Ratio can signal overbought or oversold conditions. A high ratio suggests overbought conditions, indicating that prices may be due for a correction or reversal. A low ratio suggests oversold conditions, indicating that prices may be poised for a rebound.
Final Thoughts
In conclusion, the Bid-Ask Volume Ratio Indicator stands as a pivotal tool within the realm of trading analysis. This indicator goes beyond mere numbers, offering traders a lens through which they can decode market sentiment. With its ability to discern the intricate dance between buying and selling pressures, it empowers traders to make well-informed decisions.
Notably, this indicator’s capacity to signal potential trend reversals provides a crucial advantage in an ever-evolving market landscape. It acts as a sentinel, raising the flag when the dynamics shift, thereby helping traders stay ahead of the curve.
Moreover, the Bid-Ask Volume Ratio Indicator serves as a trustworthy companion for confirming existing trends, providing a sense of validation for traders as they navigate various market conditions. It’s akin to a compass, ensuring they remain on the right path in pursuit of their trading objectives.
