Keltner Channels
Overview
Keltner Channels are volatility-based envelopes plotted above and below an exponential moving average using the Average True Range. Unlike Bollinger Bands, which use standard deviation, Keltner Channels produce smoother bands that are less reactive to individual price spikes. This makes them effective for identifying trend direction, overbought/oversold conditions, and volatility squeeze setups when combined with Bollinger Bands.
Key Concepts
Centre line: typically a 20-period EMA. Upper band: EMA + (multiplier x ATR). Lower band: EMA - (multiplier x ATR). Standard multiplier is 1.5 or 2.0 x ATR. Smoother than Bollinger Bands due to ATR-based calculation. Bollinger Band squeeze inside Keltner Channels signals imminent volatility expansion.
Entry Signals
Enter long when price closes above the upper Keltner Channel, signalling strong bullish momentum and a breakout. Buy on a pullback to the centre EMA line during an uptrend with price respecting the lower channel. Enter when Bollinger Bands squeeze inside Keltner Channels (TTM Squeeze) and then expand, with the breakout direction determining entry. Go short when price closes below the lower channel with confirming volume.
Exit Signals
Exit momentum trades when price re-enters the channel after trading outside it. Target the opposite channel boundary for mean-reversion trades from one channel extreme. Trail stops using the centre EMA line — exit if price closes below it on two consecutive bars. Take profits when the channel bands flatten, indicating momentum exhaustion.

Pro Tips
The TTM Squeeze (Bollinger Bands contracting inside Keltner Channels) is one of the most reliable volatility breakout signals available — master this setup. Use Keltner Channels for trend direction and Bollinger Bands for volatility extremes; combining both provides a fuller picture. Adjust the ATR multiplier to match the asset's typical volatility rather than using defaults blindly.

Average Directional Index (ADX)
The Average Directional Index quantifies trend strength on a scale from 0 to 100, regardless of direction. Developed by J. Welles Wilder, ADX is derived from two directional movement indicators (+DI and -DI) that measure bullish and bearish pressure respectively. A rising ADX above 25 signals a strengthening trend, while ADX below 20 indicates a ranging or trendless market — making it an invaluable filter for choosing between trend and range strategies.
Parabolic SAR
The Parabolic Stop and Reverse (SAR) is a trend-following indicator that plots dots above or below price to define the current trend direction and provide trailing stop levels. Developed by J. Welles Wilder, the indicator accelerates toward price as the trend matures, eventually crossing price to signal a reversal. The parabolic curve of the dots gives the indicator its name.
Vortex Indicator
The Vortex Indicator consists of two oscillating lines — VI+ (positive trend movement) and VI- (negative trend movement) — that capture the directional movement of price through the relationship between the current high and prior low, and the current low and prior high. Crossovers between these lines signal trend changes and provide entry and exit timing for trend-following strategies across any market.
Williams %R
Williams %R is a momentum oscillator developed by Larry Williams that measures the current closing price relative to the highest high over a specified lookback period. It ranges from 0 to -100, with readings above -20 indicating overbought conditions and readings below -80 indicating oversold conditions. Williams %R is closely related to the Stochastic oscillator but inverted, making it particularly responsive to price reversals.
