Trendline Break Strategy
Overview
A trendline connects successive highs or lows and visualizes the slope of a trend. When price breaks a trendline, the slope has changed — often the earliest sign of a trend reversal. This strategy trades the break and retest, entering once price confirms the broken line holds as new support or resistance.
Setup
- Instruments: forex majors, stocks, index ETFs, crypto
- Timeframe: 4H or daily
- Indicators: hand-drawn trendline, 50 SMA, ATR(14), volume
- Market regime: an existing trend that is showing signs of fatigue
A valid trendline connects at least three swing points. Lines drawn on two points are tentative, not reliable.
Entry rules
- Draw a trendline connecting at least three swing highs (downtrend) or swing lows (uptrend)
- Wait for a candle to close beyond the trendline in the breakout direction
- Wait for price to retest the broken trendline from the new side
- Enter on a reversal candle at the retest — bullish for longs after a downtrend break, bearish for shorts after an uptrend break
Stop loss
- Stop just beyond the retest extreme — below the reversal candle for longs, above it for shorts
- Alternative: 1.5 × ATR(14) from entry
- Exit if price closes back through the trendline — the break has failed
Use the stop loss calculator to set the distance.
Take profit
- First target: the most recent major swing high (long) or swing low (short)
- Trail the remainder below the 20 EMA on the breakout timeframe
- Aim for a minimum 2R; trendline breaks that mark reversals can run far
Confirm with the risk-reward calculator.
Risk management
- Risk 1% of account equity per break
- Position size = risk amount ÷ (entry − stop). Verify with the position size calculator
- Maximum two trendline break trades open on correlated instruments
- Reduce size if the trendline was steep — steep lines break easily but often re-form
When it fails
Trendline breaks fail most often when the line was drawn loosely or only touched twice. A retest that closes back through the line invalidates the trade. Always wait for the retest — entering on the break itself leads to many false starts.
