How to Identify and Trade Breaks of Structure

TL;DR

A break of structure is confirmed when price closes beyond the most recent valid high or low that supports the current trend. In an uptrend, a close below the latest low signals a bearish change; in a downtrend, a close above the latest high signals a bullish change. Correctly identifying candle-based highs, lows, and consolidation helps prevent false signals. Read on for the exact confirmation rules.

Key Insights

• A break of structure is a trend change that indicates the current market structure or order flow has been broken. It serves as a trading confluence, but the transcript presents it as something that must be interpreted through established highs, lows, and candle closures.
• An uptrend is defined by higher highs and higher lows, while a downtrend is defined by lower highs and lower lows. Consolidation is the third market condition described, with price moving sideways and no identifiable directional trend until a breakout occurs.
• A market high is formed by a move up followed by a move down. On a candle chart, this means an upward candle must be followed by a downward candle, and the highest wick or body point across those two candles marks the high.
• A market low is formed by a move down followed by a move up. The lowest wick or body point reached by the two candles marks the low, while two consecutive downward candles do not establish a low on the current time frame.
• A bearish break of structure is confirmed when a candle closes below the most recent low of an uptrend. This closure violates the pattern of higher highs and higher lows and indicates that the existing upward structure is no longer intact.
• A bullish break of structure is confirmed when a candle closes above the most recent high of a downtrend. This closure violates the pattern of lower highs and lower lows and indicates that the existing downward structure has changed.
• A higher low inside a downtrend does not confirm a bullish trend change because price can still continue downward and establish another lower low. The decisive reference is the latest high, which must be closed above before the downtrend is considered broken.
• The chart’s current time frame determines which turns qualify as highs and lows. A price point may appear as a high on a lower time frame but fail to qualify on a four-hour chart if no upward candle immediately precedes the downward move.

Questions & Answers

Q: What is a break of structure in day trading?

A break of structure, or BOS, is a change in the market’s current trend, structure, or order flow. It occurs when price closes beyond the relevant recent high or low that supports the existing trend. The concept is used as a trading confluence.

Q: How do you identify an uptrend, downtrend, and consolidation?

An uptrend forms higher highs and higher lows, while a downtrend forms lower highs and lower lows. Consolidation occurs when price moves sideways without an identifiable directional trend. Classifying the market first determines which high or low matters for a break of structure.

Q: How is a valid market high identified on a candle chart?

A market high requires a move up followed by a move down, represented by an upward candle followed by a downward candle. The high is the greatest price reached across those two candles, whether it appears in a wick or candle body. Two consecutive upward candles do not establish a high because no downward move has occurred.

Q: How is a valid market low identified on a candle chart?

A market low requires a move down followed by a move up, represented by a downward candle followed by an upward candle. The low is the lowest price reached across those two candles, using either the wick or body. Two consecutive downward candles do not establish a low because an upward move is still required.

Q: How do you confirm a bullish break of structure?

A bullish break of structure is confirmed when a candle closes above the most recent valid high in a downtrend. That close violates the existing pattern of lower highs and lower lows. A temporary higher low alone does not confirm the change.

Q: How do you confirm a bearish break of structure?

A bearish break of structure is confirmed when a candle closes below the most recent valid low in an uptrend. That close breaks the pattern of higher highs and higher lows. Smaller fluctuations above that low do not independently confirm a bearish structural change.

Q: Why does a higher low not necessarily end a downtrend?

A higher low can be temporary because price may rise, form a lower high, and then continue down to another lower low. Under this method, the downtrend remains intact until a candle closes above its most recent valid high. The close above that reference point confirms the structural change.

Q: Why does the chart time frame matter when identifying market structure?

A turning point visible on a lower time frame may not qualify as a high or low on the current time frame. In the four-hour example, a suspected high was rejected because the move lacked the required upward candle immediately before the downward move. Highs and lows must therefore be evaluated from the candles on the time frame being traded.

Summary & Key Takeaways

• A break of structure is a change in the market’s existing trend, order flow, or structure. Identifying it begins with classifying price action as an uptrend, downtrend, or consolidation. Uptrends form higher highs and higher lows, while downtrends form lower highs and lower lows. Consolidation has no clearly identifiable directional trend.

• A market high requires a move up followed by a move down, while a market low requires a move down followed by a move up. The relevant price is the highest or lowest point reached by the two candles forming that turn, whether that point appears in a wick or candle body.

• In a downtrend, a candle must close above the most recent high to break structure upward. In an uptrend, a candle must close below the most recent low to break structure downward. Temporary higher lows inside downtrends or lower highs inside uptrends do not independently confirm that the prevailing structure has changed.
