Bearish Flag Breakdown Scanner
Automated real-time scanner detecting high-conviction Bearish Flag patterns (Impulsive Downward Flagpoles & Inverted Parallel Channels), 50% Fibonacci bounce bounds, volume drying, and downward trend breakdowns across Indian equities.
How to Trade the Bearish Flag Pattern: The Downward Flagpole & Inverted Channel Strategy
The Bearish Flag is a textbook trend continuation pattern. It is initiated by a steep, sharp sell-off (the Flagpole) formed by aggressive bear candles and volume expansion, followed by a compact, parallel upward-sloping consolidation channel (the Inverted Flag) that counter-trend bounces no more than 50% of the flagpole drop before breaking down violently downward.
1. Impulsive Flagpole & Downward Momentum
A valid Bearish Flag begins with a steep, impulsive downward plunge over 3 to 15 bars with tall red candles and institutional volume expansion (≥ 1.25× 20-day Volume SMA). The height of the flagpole, H_pole = High_base - Low_trough, represents sharp aggressive selling and determines downside measured targets.
2. Parallel Consolidation Channel (Flag vs Pennant)
Following the flagpole drop, price pauses in a small rectangular upward-sloping or flat consolidation channel (the Inverted Flag). Bound by two strictly parallel trendlines (|Slope_U - Slope_L| ≈ 0), price forms higher swing highs and higher swing lows within a constant corridor width, rather than converging to an apex like a pennant.
3. 50% Fibonacci Bounce Rule & Volume Contraction
Fibonacci Bounce Ceiling: The counter-trend bounce must never retrace more than 50% of the flagpole drop (maximum 61.8% tolerance). A deeper bounce indicates strong buyers and invalidates the bear continuation.
Volume Contraction: Trading volume must dry up significantly during the upward flag bounce, reflecting lack of real buyer conviction before the next leg down.
4. Breakdown Confirmation, Targets & Stop Loss
Flagpole Height = High_base - Low_trough
Target 1 = Breakdown Level - 0.50 × H_pole
Target 2 (Full Pole) = Breakdown Level - 1.00 × H_pole
Stop Loss = Breakdown Bar High or Highest Swing High in Flag
5. Indicator Synergy: Volume, Bollinger Bands, Moving Averages & Fibonacci
Spikes on flagpole sell-off, contracts during the gentle counter-trend bounce, and surges ≥ 1.2× SMA on breakdown confirmation.
Bands pinch tightly during the upward flag consolidation (volatility compression) and widen violently as the breakdown accelerates.
Price remains capped beneath descending 20 EMA and 50 EMA lines, confirming the dominant higher timeframe institutional downtrend.
Measures bounce resistance at 38.2% and 50% levels, providing high-probability short entry triggers with tight risk parameters.
