Smart Money Concepts, without the mysticism
BOS, CHoCH, order blocks and fair value gaps — what each one means mechanically, and where they help.
Structure is just a sequence of swings
A market is in an uptrend while it keeps printing higher highs and higher lows. That is the whole definition. Smart Money Concepts (SMC) gives names to the moments that sequence changes, which is useful, but the names are not magic.
Our engines detect swings with a fixed lookback: a bar is a swing high if its high is the highest of the three bars either side of it. Change that lookback and every downstream label changes with it — which is why we publish the number.
BOS vs CHoCH
A Break of Structure (BOS) is a close beyond the previous swing in the direction of the existing trend: continuation. A Change of Character (CHoCH) is a close beyond the previous swing against the trend: the first evidence the sequence is breaking.
We use BOS on the higher timeframe as bias, and CHoCH on the lower timeframe as the trigger. That combination is the core of the SMC Hybrid engine: the H4 says which way, the M15 says when.
Order blocks and fair value gaps
An order block is the last opposing candle before an impulsive move — the area price left in a hurry. A fair value gap is a three-bar pattern where the middle bar's range leaves an untraded gap between the first and third bar's wicks.
Both are just zones where price moved inefficiently and often returns. They are not orders from institutions; nobody can see that. Treat them as levels with a slightly better than random chance of reaction, and always pair them with a stop.
Where SMC fails
In a range, every swing break is a CHoCH and every candle is an order block. The concepts need an impulsive market to mean anything, which is why our SMC engines sit flat for days and then cluster several trades together.
