Change of Character vs. Break of Structure: CHoCH vs. BOS

BOS vs CHoCH: Market Structure Strategies Focusing on Break of Structure and Change of Character

As buyers and sellers interact daily in financial markets, they leave footprints on price charts. These footprints can be used to gain insights into what can possibly happen in the near future.

When it comes to large financial entities, this is even more true. These players constantly manipulate prices in order to ensure liquidity.

Institutional players are often called Whales. The reason for that is that they have enormous financial power. They execute massive orders and with that are able to engineer price movements just to absorb the orders of retail traders.

Learning Smart Money Concepts is a must to help you identify and understand what institutional players might be doing.

SMC, another name for Smart Money Concepts, relies on identifying 2 main signals: the break of structure and change of character.

By identifying these two patterns, you’ll be able to understand market structure direction, allowing you to benefit from trend continuation or market reversals.

Explaining the ICT Concept: What is BOS and CHoCH

Forex traders started massively adopting SMC trading strategies somewhere in the early 2010s. But the idea of tracking large institutional players, what we call the smart money, has been around since the 1920s, with the development of the Wyckoff Method.

The break of structure and the change of character are some of the most important market elements among smart money concepts.

In essence, the break of structure confirms the continuation of the trend. When prices close beyond a prior swing point, a true break happens. In bullish markets, it is defined by higher highs and higher lows.

Remember: a true BOS only happens when the price closes above the previous peak.

A change of character does not represent a trend reversal, but instead serves as an early warning sign. A CHoCH indicates that the trend could be losing momentum and a reversal is around the corner.

Picture a bearish trend. For it to be valid, we must have lower lows and lower highs. A bullish CHoCH will be triggered when the asset fails to drop further and the price breaks above the prior high.

I invite you to think of these concepts as:

• Break of Structure -> A proof of momentum.
• Change of Character -> One of the first signals of shifting momentum. Highly important for capital preservation.

Break of Structure vs Change of Character: Concepts & Comparative Table

When we compare both by analyzing the differences between CHoCH vs BOS, we learn how their applications largely differ.

Ideally, you wouldn’t want to exclusively apply one or the other. Both should be applied in conjunction within a unique trading system.

Let’s take a look at the CHoCH. If you decide to exclusively focus on this structure, you’ll fall victim to engineered fakeouts. Institutional players are able to move prices to key levels just to trap participants who enter the market prematurely. That, by itself, is how a large percentage of retail lose money every day on financial markets.

CHoCH can be a bit trickier to trade than BOS. BOS is highly useful when applying swing trading strategies, as it offers the opportunity to benefit from an established trend, allowing you to enter the market at favorable points. These points give you “cheap” stop-losses and a large window for letting profits run.

	Break of Structure (BOS)	Change of Character (CHoCH)
Primary Function	Confirms trend continuation	Early signals for possible market reversal
Structural Action	Penetrates prior high/low in trend direction	Penetrates opposing structural points
Market Bias	Maintains an existing directional thesis	Forces re-evaluation
Entry Reliability	Very high	Moderate. Serves more like a warning sign rather than a full-on entry plan
Risk Profile	Safer, since it aligns with the dominant momentum (trade with the trend mentality)	Riskier, since it attempts to catch the early stages of a trend reversal.

Real-world Examples to Enhance Your Trading Strategy

Now that we know some key concepts and what makes CHoCH and BOS different from each other, let’s take a look at some real-world examples.

Generally, the Forex market offers some really cool short-term structures for us to evaluate. But even if you’re into other markets, what you learn here is still valid.

In the example above, we have the Daily price action chart for the Euro/U.S. Dollar on TradingView. It perfectly shows us a bullish Break of Structure sequence.

The market is consistently presenting higher highs and higher lows.

The most important thing to notice is how the structure is validated when the hourly candlestick body decisively closes above the resistance level of the previous high. We’re not merely piercing through, we are completely breaking the resistance with total confidence.

This signals that institutional players are maintaining absolute control of the order flow. They are absorbing supply and pushing prices higher.

This other example, still taken from a daily price chart for the Euro/U.S. Dollar, shows us how the CHoCH manifests on the chart.

On the left, we have an established sequence of lower lows and lower highs, which defines the bearish trend. This is all evidenced by the BOS labels.

At a certain point, prices find a strong support. No candlestick is able to close considerably below that support line.

When the price fails to go down, it rallies all the way up to the last high before the last BOS.

Again, not only the price pierces through, but the hourly candlestick effectively closes above that level. With this confirmation, we have a leading warning that a new macro trend can emerge.

As I said, CHoCHs are a bit trickier than BOS. They’re not that obvious and there are a lot of fake CHoCHs out there. The only tip I can give you is to immerse yourself in these structures to effectively understand what the differences are between internal and external structures. It’ll take a long time to be effective in differentiating them on a daily basis, but the effort is worth it.

Common Mistakes When Working With Reversal Trading

Overall, when using price charts for trading, most mistakes come from misinterpreting signals.

Treating a simple wick penetration as a valid structural shift, for example, is one of the most classical mistakes. A result of anxiety while trading. If the candlestick’s body doesn’t close beyond the swing point, the market simply executed a liquidity sweep.

Institutional players are constantly hunting for retail stop-losses. They do that by pushing prices a bit past obvious highs or lows, just to bring them back in. This is called a false breakout. A solid, true breakout requires a body close and trading volume.

Another beginner mistake is confusing internal shifts with significant macro movements. When price breaks occur at minor internal levels, beginners assume a macroeconomic shift happened. But, more often than not, that’s not exactly true.

Some tips to avoid falling into these beginner traps are:

1. Pick one higher timeframe to determine the macro trend.
2. Use the lower timeframes to define entry triggers.
3. Ensure every single trade is aligned with the institutional flow. You’re not following the herd, you’re following the smart money.

Conclusion

Smart money concepts have been around for a while. But most retail traders have barely heard of it. The number of those who have mastered it is even lower.

The reason why is not complex, though. Structural concepts go beyond candlestick patterns and indicators. It does require thousands of hours studying live charts to master them.

During your journey, you will probably have to deal with drawdowns and frustrating fakeouts. But that’s a part of it. The market will test your resilience every day.

For this specific reason, I can’t help but finish this article by reminding you of the importance of risk management. By focusing on learning and capital preservation, you will have time on your side.

As soon as you have developed an effective strategy to reading institutional footprints, you will have a path to success. You will become a master in reading supply and demand on price charts, and I guarantee you that will put you among the top % of retail traders.
