Donchian Channel

Donchian uses the highest high and lowest low over N periods (price extremes), while Bollinger uses standard deviations from a moving average. Donchian is better for breakout trading; Bollinger is better for volatility and mean reversion strategies.

No, wait for a confirmed close above/below the channel. Intraday touches often reverse by close. The close confirms that price genuinely broke through, not just spiked temporarily.

Daily charts are most reliable for swing trading. Weekly for position trading major trends. 4H for active swing trading. Lower timeframes generate more signals but also more false breakouts.

Roughly 40-60% of breakouts fail in typical conditions. This is normal for breakout systems. The key is that successful breakouts generate profits larger than the accumulated small losses from failures.

Yes, breakouts below the lower channel signal bearish momentum. Enter short when price closes below the lower channel, with stop at the middle line or upper channel. Same principles apply in reverse.

They used faster exits (10-day for System 1) than entries (20-day) to lock in profits more quickly. Entries require significant breakouts for confirmation, but once in profit, a faster exit preserves gains without waiting for full trend reversal.

Rank signals by quality: ADX level, volume, channel width contraction, and higher timeframe alignment. Take highest-ranked signals first. Apply correlation limits to avoid concentrated positions in related instruments.

Not necessarily. Filtering by ADX (> 20-25), volume (> average), and channel width (contracted) improves win rate. Quality over quantity - fewer better signals outperform many weak signals.

In System 1, if the previous 20-day breakout was profitable, skip the next signal. This filtered entry reduced whipsaws after big winners (which often preceded consolidation). System 2 had no such filter.

Common combinations: ADX for trend confirmation, volume for conviction, RSI for overbought/oversold filter, MACD for momentum. Use Donchian for entry/exit levels, other indicators for signal validation.

Calculate the ratio of current volatility to average volatility (e.g., ATR14 / Average ATR). Multiply base period by this ratio. High volatility extends period (fewer false signals); low volatility shortens it (capture opportunities).

A well-implemented Donchian system with filters typically achieves Sharpe 0.7-1.1 over long periods. Unfiltered systems around 0.5-0.8. Results vary with market conditions - trending markets improve metrics.

Expectancy = (Win Rate × Average Win) - (Loss Rate × Average Loss). For example: (0.40 × £400) - (0.60 × £100) = £100 per trade. Positive expectancy despite low win rate due to larger wins.

Typically use 2-3 years in-sample (for statistical significance) and 6-12 months out-of-sample. Walk forward quarterly or semi-annually. Ensure enough trades in each period for reliable statistics.

Upper channel informs call strike selection; lower channel informs put strikes. Middle line can serve as short strike for spreads. Channel width helps gauge spread width. Breakout entry triggers options position.
