Andrews' Pitchfork
Three-point trend channel for price action analysis
Overview
Andrews' Pitchfork is a powerful price action tool that uses three key price points to construct a parallel channel forecasting future price movement. The tool is based on the principle that after a swing leg (up or down), price tends to oscillate within parallel trend lines, creating predictable support and resistance zones.
Developed by Alan Andrews, this technique involves selecting three points—a swing low followed by a swing high and another swing low (or vice versa in downtrends)—to establish the pitchfork's middle line and channel boundaries. The middle line acts as a balance point or fair value, while the upper and lower lines define potential reversal zones.
Professional traders use Andrews' Pitchfork to identify potential continuation zones, breakout zones, and mean reversion targets. It's particularly effective in markets with distinct trends and periodic retracements, making it a staple in swing trading and position trading strategies.
Formula
Andrews' Pitchfork construction involves three key price points:
Parameters
| Parameter | Type | Default | Description |
|---|---|---|---|
| Point 1 (Pivot) | Price Level | Manual | First swing high or low that initiates the trend structure |
| Point 2 (Reaction) | Price Level | Manual | Opposite extremum defining the initial impulsive leg |
| Point 3 (Correction) | Price Level | Manual | Retracement point that completes the initial formation |
Common Use Cases
1. Channel Breakouts
Price breaking above the upper pitchfork line signals continued momentum while breaks below the lower line suggest trend reversal or acceleration downward.
2. Mean Reversion Trading
Traders buy when price touches the lower channel line and enter short at the upper line, expecting mean reversion to the central line.
3. Support/Resistance Prediction
The pitchfork lines project forward where support and resistance should form, helping traders plan entries and exits ahead of time.
4. Trend Confirmation
Price oscillating within the pitchfork with the central line as balance point confirms trend health; breaks suggest structural changes.
Advantages & Limitations
✓ Advantages
- Visual Clarity: Immediately shows potential reversal zones and support/resistance ahead of price arrival.
- Predictive Power: Channels adapt to market conditions and project future price interaction zones.
- Scalability: Works effectively across multiple timeframes from intraday to longer-term trend analysis.
- Rule-Based Entries: Clear entry/exit rules based on channel interactions reduce emotional trading decisions.
! Limitations
- Manual Point Selection: Accuracy depends entirely on identifying correct swing highs/lows; wrong points create invalid channels.
- Assumption of Parallel Lines: Assumes price will maintain parallel channel structure, which doesn't always hold in choppy markets.
- No Volatility Adjustment: Channel width doesn't account for changing market volatility or regime shifts.
- Lagging Signal: Based on historical price structure; doesn't lead sudden breakouts or black swan moves beyond channel.
Tips & Best Practices
⚡ Multiple Time Scales
Draw pitchforks on multiple timeframes—longer timeframe pitchforks show macro direction while shorter ones identify tactical entry/exit zones.
📊 Combine with Volume
Heavy volume at pitchfork lines increases confidence in support/resistance. Low volume touches should be treated with more caution.
🔄 Trend Confirmation Tool
Use the central line as a trend balance point. Strong trends maintain price above (up) or below (down) the middle line—crossovers suggest weakening.
⚠️ Avoid Redraws
Once drawn based on confirmed swing points, don't continuously redraw pitchforks. Objectivity requires committing to initial structure.
Example Strategy
1. Setup: Draw Valid Pitchfork
On a 4H or daily chart, identify a clear swing point (P1), the opposite extreme (P2), and a retracement point (P3). Draw the pitchfork channels extending forward.
2. Entry: Channel Interaction
Buy at the lower pitchfork line with tick volume confirmation in uptrends. In downtrends, short at the upper line. Use central line as target for mean reversions.
3. Stop Loss: Channel Breakout
Set stop loss 1-2% beyond the outer channel line. Closes beyond the pitchfork signal invalidation of the pattern and potential trend reversal.
4. Target: Next Resistance Level
For mean reversion trades, exit at the central line. For trend continuation trades, take profit at the opposite pitchfork line or previous swing extremes.
