What is Liquidity?
In SMC, liquidity refers to clusters of pending orders sitting above old swing highs and below old swing lows. Retail traders place their stop-losses at these predictable levels. Institutions need these orders to fill their own large positions.
Buy-side liquidity forms above old highs and equal highs, where short sellers have placed their stop-losses. Sell-side liquidity forms below old lows and equal lows, where long traders have placed their stops.
How Institutions Use Liquidity
Institutions deliberately drive price toward these liquidity pools to trigger the stops, absorb the resulting orders, and then reverse in their intended direction. This is why markets so often push just beyond a key level before reversing sharply — the sweep was intentional.
Once you understand this, you stop placing stop-losses at obvious levels. Instead, you place them beyond the next significant structure, out of reach of the most predictable sweeps.
Identifying Liquidity Sweeps in Real Time
A liquidity sweep is characterised by a fast, wick-heavy push beyond a previous high or low, followed by an immediate and sharp reversal back inside the prior range. The candle often has a very long shadow with a small body.
When you see this pattern at a key level, the sweep is likely complete. Wait for a lower-timeframe confirmation — a CHoCH or order block — and enter in the direction of the reversal.
