Triangle Breakout Strategy

Overview

Triangles are continuation patterns where price coils between converging trendlines. Ascending triangles (flat top, rising bottom) lean bullish; descending triangles (flat bottom, falling top) lean bearish; symmetrical triangles break either way. The trade triggers on the breakout with volume.

Setup

• Instruments: forex pairs, stocks, crypto
• Timeframe: 4-hour or daily
• Pattern requirements: at least 2 touches on each side, converging trendlines
• Indicators: trendlines, volume, ATR(14), 50 SMA for higher-timeframe context

Entry rules

1. Identify the triangle type and its apex direction
2. Wait for a candle to close outside the trendline in the breakout direction
3. Confirm with above-average volume on the breakout candle
4. Enter at the next bar's open, or on a retest of the broken trendline

Triangle bias

Pattern	Bias	Structure
Ascending	Bullish	Flat resistance, rising support
Descending	Bearish	Flat support, falling resistance
Symmetrical	Neutral	Break direction follows

Stop loss rules

• Stop: just inside the triangle, beyond the breakout candle's opposite side
• Alternative: 1 × ATR(14) beyond entry
• Maximum risk per trade: 1% of account
• Exit if price closes back inside the triangle

Take profit rules

• Target: measured move — the widest part of the triangle projected from the breakout
• Secondary target: prior swing high/low in the breakout direction
• Scale out: 50% at target 1, 50% trail with a 20 EMA
• Minimum RR: 2:1

Risk management

Parameter	Value
Risk per trade	1% of account
Max concurrent triangles	3
Position size	Risk ÷ (entry − stop)
Apex filter	Skip trade if breakout is within 10 bars of the apex
Volume filter	Breakout volume > 1.5× average

Use the position size calculator and the risk-reward calculator for every entry.

Common mistakes

• Trading the breakout before the apex (low volatility, false moves)
• Forcing a direction on symmetrical triangles — wait for the break
• Ignoring higher-timeframe trend — triangles work best as continuations

Key principle

Triangles are coiled springs; the wider the base, the larger the projected move. Wait for the close, confirm volume, and let the measured-move target do the work.
