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.

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.
Stochastic RSI
The Stochastic RSI applies the stochastic oscillator formula to RSI values rather than raw price data, creating a more sensitive momentum indicator that oscillates between zero and one. By measuring where the current RSI sits relative to its own range over a lookback period, the Stochastic RSI generates faster overbought and oversold signals than either the stochastic or RSI alone, making it particularly useful for timing entries within established trends.
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.
Ichimoku Cloud
The Ichimoku Kinko Hyo (Ichimoku Cloud) is a comprehensive indicator system that defines support and resistance, identifies trend direction, gauges momentum, and generates trading signals — all in a single glance. Developed by Goichi Hosoda, the system consists of five lines and a shaded cloud (Kumo) that projects into the future, providing a uniquely forward-looking view of market equilibrium.
