How is a Symmetrical Triangle (Wedge) consolidation chart pattern constructed, and how do technical traders trade the formation?

[ A ]Constructed by drawing two parallel horizontal lines that never converge across 50 years of trading.

[ B ]Constructed by drawing converging trendlines connecting a series of lower highs and higher lows as price volatility contracts; traders wait for a decisive breakout above the upper resistance line (buy signal) or breakdown below the lower support line (short/sell signal) confirmed by rising volume.[ CORRECT ]

[ C ]Traders must buy immediately when price touches the center of the triangle without waiting for any breakout.

[ D ]A Symmetrical Triangle guarantees that trading in the security will be permanently suspended by SEBI.

Takeaway

Option B is correct: Constructed by drawing converging trendlines connecting a series of lower highs and higher lows as price volatility contracts; traders wait for a decisive breakout above the upper resistance line (buy signal) or breakdown below the lower support line (short/sell signal) confirmed by rising volume.

Derivation

A Symmetrical Triangle (or Coil/Wedge) represents a consolidation phase where market buyers and sellers reach a temporary equilibrium, creating progressively lower swing highs and higher swing lows bounded by converging trendlines (each line connecting at least two swing points). Volatility and trading volume contract toward the apex of the triangle. The pattern is neutral until a decisive breakout occurs: A breakout above the upper descending trendline triggers a long trade, while a breakdown below the lower ascending trendline triggers a short trade. Target price is projected by measuring the vertical height of the triangle at its widest base. This tests consolidation patterns. The common error is trading prematurely inside the apex.

Why the others fail

A — Constructed by drawing two parallel horizontal lines that never converge across 50 years of trading.

Two parallel horizontal lines form a Rectangle or Channel consolidation range, not a converging Symmetrical Triangle.

C — Traders must buy immediately when price touches the center of the triangle without waiting for any breakout.

Entering in the middle of a contracting triangle without breakout confirmation exposes traders to severe whipsaw losses.

D — A Symmetrical Triangle guarantees that trading in the security will be permanently suspended by SEBI.

Symmetrical triangles are standard market consolidation chart formations, having no connection to regulatory trading suspensions.
