Sell-side liquidity, or SSL, is the mirror image of BSL: the pool of sell orders resting below the market. These are mostly stop losses from long traders and breakout sell stops. When price falls into them, they trigger and add selling pressure exactly where a large buyer might want fills.

How to spot it
Mark swing lows and equal lows. Two or more lows at a similar price form a stronger pool because everyone places protective stops just under obvious support. A clean, flat double bottom is one of the most reliable liquidity magnets on the chart.
How SMC traders use it
In a bullish scenario, price may dip into sell-side liquidity to trigger long stops and provide fills for large buyers before rallying. So a sweep of SSL followed by a strong reversal is a classic long context — but only when structure and confirmation agree, since a break of the low can also mean genuine continuation down.
Sell-side liquidity sits below lows — mostly long stops and breakout sells that price may run before reversing up.
