Descending Triangle Breakdown Scanner
Automated real-time scanner detecting high-conviction Bearish Descending Triangle patterns (Continuations & Reversals), horizontal support floor depletion, and downside breakdowns across Indian equities.
How to Trade the Descending Triangle: Continuation vs Reversal
The Descending Triangle is a quintessential classical bearish formation characterized by a flat horizontal lower support floor and a descending upper trendline of lower swing highs. It portrays systematic institutional distribution: while buyers attempt to defend a static support floor, sellers become increasingly aggressive, offloading shares at successively lower price points until the support floor collapses.
Market Psychology & Structural Mechanics
The Descending Triangle demonstrates steady seller dominance over dip-buyers. While institutional buyers or bargain hunters step in at a predetermined static floor, rallies off that floor become weaker and shorter with each attempt. This creates a distinct pattern of Lower Highs ($H_1 > H_2 > H_3$).
Each successive decline back to the support floor consumes the available buying bids. When bids are completely depleted, buyers step back and stop-loss orders trigger simultaneously, triggering a sharp and swift downward cascade.
Volume Confirmation & Breakdown Rules
1. Contraction During Pattern Formation: Volume should dry up as the price oscillates between the downward-sloping resistance line and the horizontal support floor. This signifies diminishing liquidity and pending explosive volatility.
2. Volume Expansion on Breakdown: A high-conviction breakdown requires an expansion in daily trading volume to ≥ 1.5x – 2.0x the 20-day average. Breakdown days accompanied by institutional delivery volume confirm high conviction behind the downward break.
Measured-Move Downside Target Formula
The classical downside price objective is calculated using the maximum vertical height of the triangle pattern established at its widest base:
Target 1 (−100% Measured Move) = Breakdown Level − Triangle Height
Target 2 (−161.8% Fibonacci Extension) = Breakdown Level − (1.618 × Triangle Height)
Downward measured moves often unfold faster than upward moves due to panic selling and forced liquidations.
Dual Stop Loss Placement & Execution Playbook
Structural Stop Loss: Placed just above the most recent lower swing high ($H_{\text{last}}$). This keeps short trades protected while allowing the market room to retest the broken floor as resistance.
Breakdown Stop Loss: Placed just above the breakdown level or the high of the breakdown candle. Suitable for intraday shorts or option traders with tight risk parameters.
F&O Trading Playbook: Buy Bear Put Spreads or Out-of-the-Money monthly Put options upon daily candle close below the floor. Avoid aggressive shorting if the breakdown occurs directly into high-timeframe horizontal support.
