Trading in financial markets requires not only intuition but also a structured, data-driven approach. The Bullish Reversal Bar Strategy is a powerful methodology designed to identify high-probability trend reversals using a combination of candlestick patterns, momentum indicators, and trend confirmation tools. Rooted in the principles developed by Bill Williams, this strategy leverages the Bullish Reversal Bar, Williams Alligator, and Williams Fractals to generate precise long-entry signals while dynamically managing exits based on evolving market conditions.
This guide breaks down the strategy’s core mechanics, justification, and performance metrics—offering traders a comprehensive understanding of how to apply it effectively in real-world scenarios.
Core Components of the Strategy
The Bullish Reversal Bar Strategy operates exclusively on long positions, aiming to capitalize on reversals from bearish to bullish trends. It combines three key technical elements:
- Bullish Reversal Bar (Candlestick Pattern)
- Williams Alligator (Trend Identification)
- Williams Fractals (Reversal Confirmation)
These components work in synergy to filter out noise and focus only on high-confidence trade setups.
1. Bullish Reversal Bar: The Entry Trigger
The foundation of this strategy lies in the Bullish Reversal Bar, a single candlestick pattern that signals potential upward momentum after a downtrend. Two conditions define this pattern:
- The candle must close in its upper half.
- Its high must remain below all three lines of the Williams Alligator (Jaw, Teeth, Lips).
This placement below the Alligator lines confirms that the market is still in a downtrend phase—making the bullish close a contrarian signal with strong reversal potential.

2. Williams Alligator: Gauging Market Trends
Developed by Bill Williams, the Williams Alligator uses three smoothed moving averages to determine whether the market is trending or consolidating:
- Jaw (Blue Line): 13-period SMA shifted 8 bars forward
- Teeth (Red Line): 8-period SMA shifted 5 bars forward
- Lips (Green Line): 5-period SMA shifted 3 bars forward
When these lines are intertwined, the “Alligator is asleep,” indicating a sideways or range-bound market. When they begin to fan out in alignment—especially with Lips above Teeth and Teeth above Jaw—the Alligator “wakes up,” signaling a strong uptrend.
In this strategy, the Alligator acts as a trend filter. A valid setup occurs only when price action remains below all three lines, ensuring the reversal is identified early in the cycle.
3. Williams Fractals: Confirming Reversal Points
Fractals help identify potential turning points in price. A Down Fractal forms when the lowest low is flanked by two higher lows on each side—indicating possible bullish reversal territory. Conversely, an Up Fractal suggests bearish resistance.
In this strategy, fractals assist in exit decisions. Once a long position is opened, the system monitors for fractal-based trend shifts combined with Alligator crossovers to determine when the uptrend may be losing steam.
Trade Execution Rules
The strategy follows a strict set of rules for entering and exiting trades:
Entry Condition:
- A Bullish Reversal Bar forms during a downtrend (high below Alligator lines, closes in upper half).
- Optional filters: MFI shows "squat" state in recent bars; AO is decreasing.
Trade Activation:
- Long position opens at one tick above the Bullish Reversal Bar’s high.
- Initial stop loss is placed at the bar’s low.
Trade Cancellation:
- If price hits the low before reaching entry, the setup is invalidated and canceled.
Exit Condition:
- The trade remains active until the Williams Alligator and Fractals indicate a shift from uptrend to downtrend.
- No fixed take-profit level—exit is dynamic and trend-based.
Optional Filters for Enhanced Accuracy
To improve signal quality, users can enable two additional filters:
Awesome Oscillator (AO)
The AO measures momentum by comparing 5-period and 34-period SMAs of median prices:
AO = SMA5(Median Price) − SMA34(Median Price)
A decreasing AO bar adds confirmation that bearish momentum is weakening—increasing the likelihood of a bullish reversal.
Market Facilitation Index (MFI)
The MFI evaluates price movement relative to volume:
MFI = (High − Low) / Volume
Four states are recognized:
- Green Window: Rising MFI + rising volume → strong trend
- Fake Window: Rising MFI + falling volume → weak trend
- Squat Window: Falling MFI + rising volume → consolidation before breakout
- Fade Window: Falling MFI + falling volume → lack of interest
The strategy focuses on Squat Window bars—where high volume fails to move price—indicating accumulation and increased reversal probability.

Backtested Performance Metrics (2023–2024)
The strategy was rigorously tested over a two-year period under realistic market conditions:
- Test Period: January 1, 2023 – December 31, 2024
- Exchange Simulation: Binance (0.1% commission + 5-tick slippage)
- Initial Capital: 10,000 USDT
- Position Size: 50% of capital per trade
Key Results:
- Net Profit: +5,472.66 USDT (+54.73%)
- Total Trades: 103
- Win Rate: 33.98%
- Profit Factor: 1.634
- Max Single Loss: -5.29%
- Max Single Profit: +29.99%
- Average Profit per Trade: +53.13 USDT (+0.94%)
- Average Trade Duration: 76 hours (~3 days)
Despite a relatively low win rate, the high profit factor indicates strong risk-reward asymmetry—winning trades significantly outweigh losses.
Frequently Asked Questions (FAQ)
Q: Why is the win rate only ~34% yet the strategy is profitable?
A: The strategy prioritizes high-reward setups over frequent wins. With a profit factor above 1.6, average gains per winning trade are more than double the average loss—making consistency more important than frequency.
Q: Can this strategy be used on any asset or timeframe?
A: While applicable across assets, optimal results were observed on 4-hour ETH/USDT charts. Higher timeframes reduce noise and improve signal reliability.
Q: Is there a fixed stop-loss or take-profit?
A: No. Stop-loss starts at the reversal bar’s low but exits are dynamic—based on Alligator and fractal-based trend changes—allowing profits to run during sustained uptrends.
Q: How do MFI and AO filters improve performance?
A: These filters add confluence by confirming weakening momentum (AO) and accumulation phases (MFI squat), reducing false signals during choppy markets.
Q: What does “one tick above” mean in entry execution?
A: It refers to the smallest possible price increment above the reversal bar’s high, ensuring entry only upon confirmed breakout.
Q: Can this strategy be automated?
A: Yes. Users can set up alerts using webhook messages ({{strategy.order.alert_message}}) to integrate with trading bots or external execution systems.
