What is BOS in Trading?

In the world of modern trading, understanding market structures has become essential for making profitable decisions. 📉 One of the most powerful technical concepts to master is the Break of Structure, better known as BOS in trading. This term refers to a significant break in the market structure, signaling an upward or downward trend. In this article, we will explore in depth what BOS is in trading, how to identify BOS, and why this concept is essential for traders in financial markets, especially in forex. Whether you are a beginner or experienced, integrating BOS into your trading strategy can transform your market approach.
Understanding the Break of Structure (BOS)
Definition of BOS
The Break of Structure (BOS) is a technical signal indicating that a price movement has surpassed a key area of support or resistance. This allows traders to detect a trend change, whether it is a continuation or a reversal. 🧠
A BOS occurs when the price breaks a previous structural high or low, indicating a change in the behavior of buyers or sellers.

According to a report by Bloomberg Intelligence (2024), nearly 72% of professional technical traders consider structure breaks as more reliable trading signals than classic indicators such as moving averages.

Identifying BOS in Financial Markets
How to Identify a BOS
To identify BOS, traders must analyze price charts using technical indicators and analysis tools. Here are the key steps:
- Observe the current trend across multiple time frames
- Note the latest significant highs and lows
- Check if a high/low is broken with momentum
- Confirm with volume, RSI, or moving average
“To filter out false BOS signals, I recommend always combining a break with a significant increase in volume or an RSI divergence,” explains Julien Lefèvre, technical analyst at IG France.
📈 A valid BOS is often confirmed by an acceleration in price movement and increasing volume.
Concrete example:
On the EUR/USD, if the price breaks a previous high after a retracement, with an RSI exceeding 60, this may signal a bullish BOS and a potential buy signal.

Trading Strategies Based on BOS
Integration into a Trading Strategy
An effective trading strategy around the BOS relies on the combination of several elements:
- Market structure analysis
- BOS validation with a technical indicator (RSI, MA, MACD)
- Risk management (SL/TP)
- Entry on the pullback or at the break
A study by Forex Factory (2023) shows that strategies integrating BOS + EMA 50 record 18% more success than those without confirmation.
🎯 Pro tip: Use the BOS to anticipate major movements in forex, stocks, or indices available on platforms like Pocket Option, which offers over 100 assets to trade 24/7 via OTC.

BOS Compared to Other Market Indicators
Why Combine BOS with Other Tools?
An isolated BOS can sometimes be a false signal. That’s why professionals often combine BOS with other technical indicators:
- RSI
- Moving averages
- MACD
“An isolated BOS only makes sense if it is contextualized,” states Clara Benhaïm, strategist at Société Générale Markets.
📉 Example: A bearish BOS is more reliable if the RSI is oversold and the MA50 crosses the MA200 downwards.
