Break of Structure — BOS
BOS is a valid break of a major swing in the prevailing structural direction and confirms continued control.
Simple and precise definition
BOS is a valid break of a major swing in the prevailing structural direction and confirms continued control.
The source calls BOS confirmation. Judge it by a meaningful level, clean movement and ability to continue; a wick touch alone is insufficient.
How it works, step by step
In an uptrend inspect the Swing High break; in a downtrend inspect the Swing Low break and later acceptance.
The source logic is: The source calls BOS confirmation. Judge it by a meaningful level, clean movement and ability to continue; a wick touch alone is insufficient.
Separate observation from interpretation: the numbers show only a price path; an SMC label still needs this lesson’s criteria. 80 → 88 → 84 → 91.5 (close 90.8)
Why it matters
Its practical importance is that BOS carries more meaning after bias and with displacement.
Place in the SMC sequence
BOS carries more meaning after bias and with displacement.
How it works, step by step
First, In an uptrend inspect the Swing High break; in a downtrend inspect the Swing Low break and later acceptance.
Then, Valid case: In an uptrend inspect the Swing High break; in a downtrend inspect the Swing Low break and later acceptance.
Finally, Invalid case: A sweep takes and rejects a level; BOS should support continuation.
Define invalidation before turning an observation into a trade.
How to identify it
In an uptrend inspect the Swing High break; in a downtrend inspect the Swing Low break and later acceptance.
Valid case: In an uptrend inspect the Swing High break; in a downtrend inspect the Swing Low break and later acceptance.
Invalid case: A sweep takes and rejects a level; BOS should support continuation.
After the observation, wait for subsequent behavior to confirm it.

Distinction from a related concept
↗ Supported case
80 → 88 → 84 → 91.5 (close 90.8): Valid case: In an uptrend inspect the Swing High break; in a downtrend inspect the Swing Low break and later acceptance. In a bullish scenario, In an uptrend inspect the Swing High break; in a downtrend inspect the Swing Low break and later acceptance.
↘ Interpretation trap
80 → 88 → 84 → 91.5 (close 90.8): Invalid case: A sweep takes and rejects a level; BOS should support continuation. In a bearish scenario, In an uptrend inspect the Swing High break; in a downtrend inspect the Swing Low break and later acceptance.
⚠ Common mistakes
First error: labeling without criteria in Break of Structure — BOS
Second error: confusing it with Liquidity sweep
Third error: turning an observation into an immediate entry without a model or risk control.
✓ Practical checklist
In an uptrend inspect the Swing High break; in a downtrend inspect the Swing Low break and later acceptance.
Valid case: In an uptrend inspect the Swing High break; in a downtrend inspect the Swing Low break and later acceptance.
Invalid case: A sweep takes and rejects a level; BOS should support continuation.
This concept is not a guaranteed entry or profit; stop, position size and model rules remain mandatory.

💡 The emphasized element is a clue; still submit the answer yourself. In an uptrend inspect the Swing High break; in a downtrend inspect the Swing Low break and later acceptance. Separate observation from interpretation: the numbers show only a price path; an SMC label still needs this lesson’s criteria.
Expected answer
B، چون سطح ساختاری با پذیرش/بستهشدن روشنتر شکسته شده است.
Assisted practice
Assisted: write one supported and one rushed interpretation of the same sequence, then state the filter that rejects the weak reading. 80 → 88 → 84 → 91.5 (close 90.8)

What to retain
Its practical importance is that BOS carries more meaning after bias and with displacement.
BOS carries more meaning after bias and with displacement.
Mental model: observe → label conditionally → wait for subsequent behavior → decide only inside a risk plan.
