Break of Structure (BoS) and Change of Character (CHoCH) Trading Strategy
Learn practical trading strategies to apply BOS and CHOCH concepts for profitable entries and exits.
Understanding Break of Structure (BOS) and Change of Character (CHOCH) in Trading
Last Updated: October 28, 2025
In this post, we will explore two important concepts in the trading world: Break of Structure (BOS) and Change of Character (CHOCH). These terms are frequently discussed among traders, especially those focusing on market structure trading. Though BOS and CHOCH may initially seem complex, we'll break them down using simple examples to ensure you grasp their significance.
Break of Structure (BOS): Key to Recognizing Trend Continuation
Break of Structure, or BOS, is a fundamental concept used to identify the continuation of a trend in market structure trading. A BOS occurs when the price of an asset breaks the previous high or low within the current trend, thereby confirming a continuation of the trend.
Break of Structure (BOS)
How Does BOS Work?
Imagine you are watching the price chart of a currency pair in Forex trading. In an uptrend, the price consistently makes higher highs and higher lows. A BOS is confirmed when the price breaks above a previous high. This point is crucial as it signals the continuation of the uptrend, encouraging traders to consider entering or staying in their positions to capitalize on the upward movement.
For instance, if the price of EUR/USD moves above its previous high after a period of consolidation, this break above the resistance level signals a BOS. Traders would interpret this as a signal to potentially buy, expecting the trend to continue pushing higher.
Change of Character (CHOCH): Indicative of Trend Reversal
Change of Character, or CHOCH, contrasts with BOS as it indicates a potential end to the current trend and a possible reversal. This shift is observed when the price fails to maintain its pattern of highs and lows corresponding to the existing trend.
Change of Character (CHOCH)
Recognizing CHOCH
Using the same Forex example, a CHOCH might occur during an uptrend if the price drops below the most recent low. This break below the strong low suggests that the market is losing steam and could be shifting from an uptrend to a downtrend or moving into a consolidation phase.
For instance, if EUR/USD breaks below a major low point after consistently forming higher highs and higher lows, this action is a CHOCH. Traders might see this as a warning sign to either exit their long positions or prepare for a potential trend reversal.

🎯 Practical Application Guide
Using BOS Signals
1. Identify the Trend: Confirm you're in a clear uptrend or downtrend
2. Watch for Break: Look for price to break above previous high (uptrend) or below previous low (downtrend)
3. Wait for Confirmation: Let the candle close beyond the structure
4. Consider Entry: Look for entry opportunities in the trend direction
5. Set Stop Loss: Place stops below the most recent swing point
Using CHOCH Signals
1. Monitor Trend Health: Watch for signs of momentum weakening
2. Spot the Failure: Price fails to make a new high (uptrend) or new low (downtrend)
3. Watch for Break: Price breaks the opposite structure (lower low in uptrend, higher high in downtrend)
4. Manage Positions: Consider taking profits or tightening stops on existing trades
5. Wait for Clarity: Let the new trend develop before entering reversal trades
📋 Key Principles to Remember
Confirm with Higher Timeframes: Check that higher timeframes support your signal before trading
Wait for Candle Close: Don't enter until the candle closes beyond the structure level
Use Proper Risk Management: Always set stop losses and position sizes before entering
Combine Multiple Signals: Look for confluence with other indicators before trading
Stay Patient: Not every BOS or CHOCH signal requires action - wait for optimal setups
Respect the Trend: BOS trades with the trend; CHOCH is a warning, not a guarantee of reversal
Understanding the nuances between BOS and CHOCH is crucial for developing effective trading strategies. Here’s how traders use these concepts:
BOS Trading Strategy: Traders look for BOS signals to confirm trend continuations. By entering trades following a BOS, they aim to capitalize on the strength of the ongoing trend.
CHOCH Trading Strategy: On the other hand, a CHOCH alerts traders about possible trend reversals. This information is vital for risk management, helping traders secure profits or cut losses before the market moves against their initial predictions.
Integrating BOS and CHOCH with Other Technical Analysis Tools
While Break of Structure (BOS) and Change of Character (CHOCH) are powerful concepts on their own, they are most effective when used in conjunction with other technical analysis tools. This multi-tool approach allows traders to confirm signals and make more informed decisions by analyzing different aspects of market behavior.
🔗 Integrating BOS and CHOCH with Other Technical Analysis Tools
While BOS and CHOCH are powerful on their own, combining them with complementary indicators can help you make more informed trading decisions.
📊 Using RSI with BOS/CHOCH
What RSI Shows:
The Relative Strength Index (RSI) measures the speed and change of price movements, helping you assess momentum strength.
Confirming BOS Signals:
- When price breaks structure upward, check if RSI is above 50
- RSI moving higher alongside price may indicate strong momentum
- RSI divergence (opposite direction from price) can be a warning sign
Spotting CHOCH Warnings:
- RSI divergence before CHOCH can indicate weakening trend
- RSI in overbought (>70) or oversold (<30) zones may signal exhaustion
- Use RSI changes as early warning before price confirms CHOCH
📈 Using MACD with BOS/CHOCH
What MACD Shows:
MACD is a trend-following indicator that shows the relationship between two moving averages, helping identify trend direction and strength.
Confirming BOS Signals:
- MACD line above signal line can support bullish BOS
- Bullish crossover near BOS may indicate trend alignment
- Expanding histogram bars can suggest building momentum
Spotting CHOCH Warnings:
- MACD crossing below signal line can support bearish CHOCH
- Shrinking histogram may indicate weakening momentum
- Zero line crossover can help confirm trend change
✅ Multi-Indicator Confirmation Approach
Consider checking multiple factors before entering trades based on BOS or CHOCH signals:
For BOS Trades:
✓ Price breaks above previous high (uptrend) or below previous low (downtrend)
✓ RSI shows momentum alignment with trend direction
✓ MACD supports the trend direction
✓ Higher timeframe confirms overall trend direction
For CHOCH Signals:
✓ Price fails to make new high/low in existing trend
✓ RSI shows divergence or momentum shift
✓ MACD shows crossover or weakening
✓ Multiple timeframes show similar structure changes

Complementary Analysis Tools:
Relative Strength Index (RSI): The RSI is a momentum oscillator that measures the speed and change of price movements. It can help confirm the momentum behind a BOS or indicate a weakening trend potentially leading to a CHOCH.
Moving Average Convergence Divergence (MACD): MACD is a trend-following momentum indicator that shows the relationship between two moving averages of a security’s price. It can be particularly useful to confirm the trend direction suggested by a BOS or to signal a weakening trend that might result in a CHOCH.
Conclusion
Mastering the concepts of Break of Structure (BOS) and Change of Character (CHOCH) is essential for anyone engaged in market structure trading. Whether you trade Forex, stocks, or any other financial instruments, these concepts can greatly enhance your analytical skills, helping you make more informed and strategic trading decisions.
