What Is Liquidity?
Liquidity is the pool of resting orders waiting to be filled. Learn buy-side and sell-side liquidity and why price is drawn to them.
The definition
In SMC, liquidity refers to the resting orders — pending orders and stop losses — that sit at and beyond key price levels. Institutions need liquidity to fill their large orders without moving price against themselves. Where there is liquidity, there is interest.
Think of liquidity as fuel. Price moves toward fuel because that is where orders can be matched efficiently.
Buy-side and sell-side liquidity
Buy-side liquidity sits above price — these are buy stops (stop-loss orders of short sellers) and buy-breakout orders resting above resistance and old highs. Price tends to rise into buy-side liquidity to fill these orders.
Sell-side liquidity sits below price — these are sell stops (stop-loss orders of long buyers) and sell-breakout orders resting below support and old lows. Price tends to fall into sell-side liquidity.
When you hear 'price swept the highs,' it means price rose into buy-side liquidity, filled the buy stops, and is now likely to reverse. The opposite is true for swept lows.
The liquidity map
Your first job on any chart is to map liquidity: where are the obvious highs (buy-side) and obvious lows (sell-side)? These are the magnets price is drawn to. Once you see the liquidity map, you stop being surprised by 'fake breakouts' — you start expecting them.
The magnet at 42,000
Bitcoin put in an old high at 42,000 weeks ago. Every trader can see it, and stops from shorts sit just above it.
- 1Map the liquidity: buy stops rest above 42,000 — short sellers' stop losses and breakout buy orders.
- 2Price grinds up toward the level over several sessions. You expect the move — it's hunting fuel, not 'breaking out'.
- 3Price taps 42,150, triggering all of it, then reverses sharply within two candles.
- 4The rally existed to fill institutional sell orders into that triggered buying. The 'new high' was the exit, not the beginning.
Once you see old highs as pools of resting orders, 'unexpected reversals' become expected.
