Smart Money Concept reads the market as large players hunting the crowd's liquidity. Here are the main ideas and how to check them with data.

The idea

SMC assumes that large players need opposing orders to build a position. Those orders sit where the crowd keeps its stops and liquidations: beyond obvious highs and lows and round numbers. So price often "sweeps liquidity" beyond a level first and only then moves in the main direction.

Key terms

Liquidity sweep — a poke through a high or low that triggers stops and reverses. Order block — the last candle before a strong impulse, where a large player is thought to have built a position. Imbalance (FVG) — a stretch price crossed too fast, leaving a gap between candles; price often returns to it. Break of structure (BOS/CHoCH) — a break of the last significant high or low that changes the trend direction.

How to check it with data

SMC's weak spot is that everything is drawn on candles in hindsight. Liquidity itself can be seen directly. The liquidation heatmap shows where leveraged positions would be force-closed. The order book heatmap shows where real limit orders sit. When an SMC "liquidity zone" lines up with a cluster on the map, the idea has money behind it.

What not to expect

SMC is a way of looking at the market, not a ready-made system. Different traders mark the same candles differently. It works better the stricter the entry and stop rules are and the more real liquidity data backs them.
