Range

Range refers to the spread between the highest and lowest prices a security trades at during a given period — a single day, a week, a month, or any timeframe. The daily range of a stock tells you the distance between its intraday high and low. A wider range implies higher Volatility and potentially more trading opportunities, while a narrow range suggests consolidation.

When a stock trades within a defined range for an extended period — bouncing between a Support level at the bottom and a Resistance level at the top — it is said to be "range-bound" or in consolidation. For example, if Reliance Industries oscillates between INR 2,400 and INR 2,600 over several weeks without breaking either level, that INR 200 band is its trading range.

Range-bound trading strategies differ fundamentally from trending strategies. In a range, traders buy near support and sell near resistance, reversing positions at each boundary. This works until the range breaks — a breakout above resistance signals the start of an uptrend, while a breakdown below support signals a downtrend. Trading Volume typically spikes during genuine breakouts.

Technical indicators adapted for range-bound markets include the RSI (which oscillates between overbought and oversold), Bollinger Bands (which contract during consolidation), and Stochastic Oscillator. Trend-following indicators like moving averages tend to produce false signals in range-bound conditions, whipsawing traders with frequent crossovers.

On Indian exchanges, many mid-cap and small-cap stocks spend significant time in ranges between quarterly earnings announcements. The range expands during events — earnings, RBI policy days, Union Budget — and contracts during low-news periods. Average True Range (ATR) is a popular technical indicator that quantifies the typical daily range, helping traders set appropriate Stop Loss levels.
