Donchian Channels plot the highest high and lowest low over a specified lookback period, creating a dynamic channel that defines the current price range. Originally popularised by the legendary Turtle Traders, Donchian Channel breakouts capture new trends at their inception by entering when price exceeds the prior range extreme. The channel width also serves as a volatility measure and position-sizing input.
The upper band is the highest high over the lookback period, typically twenty periods. The lower band is the lowest low over the same period. The midline is the average of the upper and lower bands. A breakout above the upper band signals a potential new uptrend. A breakout below the lower band signals a potential new downtrend. Channel width reflects current volatility — wider channels indicate higher volatility. The Turtle Trading system used twenty-period and fifty-five-period Donchian breakouts.
Enter long when price closes above the twenty-period upper Donchian Channel. Enter short when price closes below the twenty-period lower Donchian Channel. Use a longer period such as fifty-five periods for stronger, less frequent signals. Filter entries using the trend direction from a higher-timeframe Donchian Channel.
Exit long positions when price touches the ten-period lower channel (tighter trailing exit). Exit short positions when price touches the ten-period upper channel. Use the midline as a trailing stop for trend-following positions. Exit if the breakout fails to show follow-through within a few periods.

Donchian Channel breakouts produce many false signals in ranging markets, so trend filters are essential. The Turtle Traders combined Donchian breakouts with ATR-based position sizing and strict risk management to create one of the most successful systematic strategies in history. Simplicity is the strength of this approach — avoid over-complicating it with too many additional indicators.
Support and resistance (S/R) levels are price zones where buying or selling pressure has historically prevented the price from continuing in its current direction. Support is a floor where buying emerges; resistance is a ceiling where selling appears. S/R levels are the foundation of technical analysis and provide the framework for every trade setup.
The Relative Strength Index (RSI) and Stochastic Oscillator are bounded momentum indicators that identify overbought and oversold conditions. RSI (default: 14) ranges from 0-100; readings above 70 suggest overbought, below 30 oversold. Stochastic (default: 14, 3, 3) measures where the close falls within the recent high-low range.
Supply and demand zones are price areas where significant buying or selling previously occurred, causing a strong directional move away from the zone. Unlike traditional support and resistance which uses lines, supply and demand trading identifies zones — ranges of price — where institutional orders created imbalances. When price returns to these zones, unfilled orders may trigger a reaction, providing high-probability trading opportunities.
Multi-timeframe analysis (MTA) uses multiple chart timeframes to build a complete picture of market conditions. The higher timeframe provides trend direction and key levels. The intermediate timeframe confirms momentum. The lower timeframe provides precise entry timing. This 'top-down' approach dramatically improves trade quality.
