A Break of Structure (BOS) occurs when the price moves definitively beyond a previous significant high (for an uptrend) or low (for a downtrend), indicating a continuation of the current trend. For example, if a stock in an uptrend makes a new high above its previous peak, that's a BOS. A Break of Structure signifies that the dominant market force (buyers in an uptrend, sellers in a downtrend) remains in control and has successfully pushed prices past a key level, establishing a new higher high or lower low. This often happens after a period of consolidation or retracement, where the market pauses before resuming its primary direction. When EUR/USD breaks above 1.0950 resistance with high volume after a pullback, traders using this concept would interpret this as a strong confirmation of the uptrend and look for opportunities to enter long positions, potentially targeting the next resistance level. Conversely, a break below a significant low in a downtrend would signal continued bearish momentum, prompting traders to consider short positions.
