Liquidity Pools (BSL & SSL)

Where the resting stops are

10 min+80 XP Mark the Liquidity

Large participants cannot buy or sell their size at a single price without moving the market against themselves. They need the other side — and the biggest, most predictable concentrations of the other side are the stop orders that cluster above highs and below lows.

01Where the orders are

Above every obvious high sit buy stops: stop-losses from shorts and breakout buy orders. That is buy-side liquidity (BSL). Below every obvious low sit sell stops — sell-side liquidity (SSL). When those stops trigger, they become market orders: exactly what a large seller needs above a high, or a large buyer needs below a low.

IllustrativeThree highs at ~112 and two lows at ~101: each “double” or “triple” is a magnet, because retail traders place their stops just beyond it.

02Ranking liquidity pools

Equal highs / equal lowsTextbook “double top/bottom” stops stacked at one price
Previous day high/low (PDH/PDL)Watched by every intraday trader
Previous week / month high-lowHigher-timeframe stops and options positioning
Session highs/lows (Asia, London)Raided during the next session’s killzone
Trendline liquidityStops placed under “obvious” trendlines
Round numbersPsychological stops and option strikes
Pro insightDraw on liquidity

At any moment, ask: “Which pool is price most likely to reach next?” In a bullish structure the draw is usually the buy-side above; in a bearish structure, the sell-side below. That single question gives every trade a logical target.

03Liquidity is fuel, not a signal

A pool tells you where price is likely to travel, not when. Many traders lose money trying to fade the first touch of equal highs. The edge appears after the pool is taken — when price shows it was a raid, not a breakout. That is the next lesson.

Key takeaways
  • BSL = buy stops above highs; SSL = sell stops below lows.
  • Equal highs/lows and PDH/PDL are prime pools.
  • The draw on liquidity frames direction and targets.
  • Pools are targets and fuel — wait for the reaction.
Common mistakes
  • Putting your own stop exactly at the obvious equal low
  • Fading the first touch of a pool
  • Ignoring higher-timeframe pools that dwarf the intraday ones
