Bullish Flag Breakout Scanner
Automated real-time scanner detecting high-conviction Bullish Flag patterns (Impulsive Flagpoles & Parallel Consolidation Channels), 50% Fibonacci retracement bounds, volume drying, and explosive upward breakouts across Indian equities.
How to Trade the Bullish Flag Pattern: The Flagpole & Parallel Channel Strategy
The Bullish Flag is a premier high-conviction continuation pattern. It is initiated by a sharp, impulsive rally (the Flagpole) formed by strong momentum candles and volume expansion, followed by a tight rectangular consolidation channel (the Flag) sloping slightly downward or flat against the prior trend. Crucially, the flag consolidation must never retrace more than 50% of the flagpole before producing an explosive upside breakout.
1. Impulsive Flagpole & Momentum Velocity
Every valid Bullish Flag begins with a flagpole—a sharp, impulsive directional rally over 3 to 15 bars characterized by long green candles and heavy volume expansion (≥ 1.25× 20-day Volume SMA). The height of the flagpole, H_pole = Peak High - Base Low, reflects aggressive institutional accumulation and sets the measured-move price projection.
2. Parallel Consolidation Channel (Flag vs Pennant)
Following the flagpole rally, price pauses in a small rectangular consolidation channel (the Flag) that slopes slightly downward or flat against the prior trend. Boundaries are formed by two strictly parallel trendlines (|Slope_U - Slope_L| ≈ 0). Crucially, flags do not converge like pennants or wedges—the channel width remains uniform throughout.
3. 50% Fibonacci Retracement Rule & Volume Contraction
Fibonacci Retracement Rule: The flag consolidation must never retrace more than 50% of the flagpole's length (maximum 61.8% threshold). Deep pullbacks indicate heavy supply and invalidate the setup.
Volume Contraction: Trading volume must steadily contract and dry up during flag consolidation as smart money absorbs liquidity without distributing shares.
4. Breakout Confirmation, Targets & Stop Loss
Flagpole Height = Peak High - Base Low
Target 1 = Breakout Level + 0.50 × H_pole
Target 2 (Full Pole) = Breakout Level + 1.00 × H_pole
Stop Loss = Breakout Bar Low or Lowest Swing Low in Flag
5. Indicator Synergy: Volume, Bollinger Bands, Moving Averages & Fibonacci
Surges on the flagpole, dries up to multi-week lows during consolidation, and explodes ≥ 1.2× SMA on breakout confirmation.
Bands squeeze tightly during the flag consolidation signaling volatility contraction, then violently expand upon breakout.
Price remains firmly above rising 20 EMA and 50 EMA lines, confirming the dominant higher timeframe institutional uptrend.
