Understanding market dynamics is crucial for traders aiming to make informed decisions. One of the most revealing aspects of price movement lies in the balance between buyers and sellers at any given moment. The Buyer-Seller Strength indicator, developed by SATHYANR, offers a unique way to visualize this balance using simple yet effective calculations based on candlestick structure.
This tool does not serve as a standalone trading system but functions as a powerful analytical supplement—especially for price action traders who rely on interpreting candlestick patterns to gauge market sentiment.
How the Buyer-Seller Strength Indicator Works
At its core, the indicator analyzes the proportional relationship between a candle’s wick (or shadow) and its real body. This ratio helps reveal hidden strength in what might otherwise appear to be a straightforward bullish or bearish candle.
For instance:
- A long upper wick on a green (bullish) candle may suggest that although buyers pushed prices higher, sellers stepped in strongly near the close.
- Conversely, a long lower wick on a red (bearish) candle could indicate strong buying pressure that reversed the downtrend temporarily.
By calculating these proportions, the script quantifies buyer and seller dominance in percentage terms:
- Sellers' strength is shown as a positive %
- Buyers' strength is represented as a negative %
When you hover your cursor over any candle on the chart, the indicator displays these values in real time, allowing for quick assessment of intrabar dynamics.

This granular insight enables traders to detect potential reversals, exhaustion points, or continuation signals that aren't immediately obvious from raw price action alone.
Why Use This Indicator?
While traditional technical indicators like RSI or MACD focus on momentum and volume, few directly measure the internal struggle between supply and demand within individual candles. That’s where this tool fills a critical gap.
Price action traders often speak of “hidden strength” — subtle clues embedded in candle formation that hint at future movement. This indicator makes those clues quantifiable, helping traders move beyond subjective interpretation.
For example:
- A bullish engulfing pattern with minimal wicks suggests strong conviction from buyers.
- But if the same pattern has long upper and lower wicks, it may reflect indecision despite the closing price being higher.
The Buyer-Seller Strength script brings clarity to such scenarios by assigning numerical values to each side of the battle.
Integration into Your Trading Workflow
Although the developer emphasizes that this should not be used as a sole decision-making tool, it excels when combined with other forms of analysis:
- Support and resistance levels: Use the indicator to assess whether price rejection at key levels shows strong seller or buyer presence.
- Trend confirmation: In an uptrend, look for consistently negative (buyer-dominant) readings during pullbacks to confirm healthy momentum.
- Reversal spotting: Sudden spikes in seller strength (% positive) at resistance zones may signal an impending downturn.
Additionally, because the script is written in Pine Script and hosted on TradingView, it integrates seamlessly into most chart setups without requiring additional software.

Buyer-seller strength refers to the relative power exerted by buyers and sellers within a single candlestick. It helps traders assess who is in control during a specific period, based on wick-to-body ratios.
