Every trend is a sequence of swing highs and swing lows. While price keeps printing higher highs and higher lows, buyers are in control; the mirror holds for downtrends. The moment that sequence breaks is where structure — and often the trade — begins. Edo Smart Money Map marks these breaks automatically, but understanding them by hand makes the tool far more useful.
Break of Structure: the trend continues
A Break of Structure (BOS) happens when price closes beyond the last relevant swing in the direction of the prevailing bias — a higher high broken in an uptrend, a lower low broken in a downtrend. It confirms that the side already in control still holds it. A clean run of BOS in the same direction is the signature of a healthy trend, and each one leaves a fresh order block to watch on the next pullback.
Change of Character: control may be shifting
A Change of Character (CHoCH) is the opposite: price breaks structure against the prevailing bias — losing the last higher low in an uptrend, or reclaiming the last lower high in a downtrend. It is the first structural sign that control may be changing hands. A CHoCH is not an entry by itself; it is the cue to lower conviction in the old direction and watch how price behaves at the order block the move leaves behind. The exact same level break can be a BOS or a CHoCH — the difference is purely the context of the prevailing bias.
Why closed-bar validation matters
The value of BOS and CHoCH depends entirely on how a break is confirmed. A wick that pierces a level intrabar and closes back inside is not a break — it is often a liquidity grab. Validating structure only on closed bars removes those false signals at the cost of confirming a little later. It is the single most important rule for trading structure cleanly, and it is why non-repainting tools are worth the small delay.
