Market Structure · Lesson 02 of 06
Liquidity pools & stop runs
What it is
In Lesson 01 you learned that waiting orders are liquidity. Here's the next piece: those orders don't spread out evenly. They cluster at obvious places.
Under every obvious low, there's a pile of stop losses from people who bought. Above every obvious high, there's a pile of stops from people who shorted — plus breakout orders from people waiting to chase. Round numbers collect orders too, just because humans like round numbers.
A price zone where lots of these orders are stacked together is called a liquidity pool.
And here's the part nobody tells beginners: your stop loss is not a shield. It's an order. A sell-stop under the low becomes a market sell the moment it triggers. To a large buyer, a pool of stops is a pile of cheap coins waiting to be collected.
A stop run (or stop hunt) is when price pushes into one of these pools, triggers the orders inside, and then reverses. The pool gets drained, someone big gets filled, and price snaps back.
Why it matters
This lesson explains the single most frustrating experience in trading: you buy, you get stopped out by a quick dip, and then price rockets in the direction you predicted. Without your position.
That's not bad luck, and it's mostly not conspiracy either. It's mechanics. Big players need huge amounts of volume to fill their orders without moving price against themselves. Triggered stops are that volume. So price gets pulled toward pools the way water flows downhill.
Once you know this, your whole relationship with "support" and "resistance" changes. A level that everyone can see isn't just a level — it's a target.
The two readings, always taught together
Read bullish when
- A sweep of an obvious low that snaps right back. Price dips under the level everyone's watching, triggers the stops, and reclaims the level within minutes. The sellers are done — they were forced out — and someone big just got filled.
- Equal lows finally taken, then reclaimed. Two or three lows at the same price are a giant pool. When it's finally raided and price recovers fast, the fuel below is spent. There's often nothing left to fall on.
- A long wick below support with a strong close back above. The wick is the run; the close is the verdict.
Never alone — confirm with the close & acceptance
Read bearish when
- A push above an obvious high that fails immediately. Price pokes above resistance, triggers the short stops and breakout buys, then dumps back below. The breakout crowd is now trapped — and their stops become the next pool below.
- Grinding up into equal highs, then hard rejection after they're taken. The rally wasn't demand; it was a collection run above the highs.
- A broken low that does not get reclaimed. This is the crucial one. If price breaks support and just… stays down there, that wasn't a stop run. That was a real breakdown. The reclaim is what separates the two.
Never alone — confirm with the close & acceptance
Visual explanation
Real market example
October 16, 2023 — the fake ETF headline. A false report that BlackRock's spot Bitcoin ETF had been approved hit social media. Within minutes, BTC spiked from around $27,900 to about $30,000 — and when the report was debunked, it round-tripped the entire move almost as fast.
Why did a fake headline move price $2,000 in minutes? Because of what was sitting above the highs: short stops and breakout orders that had been stacking up for weeks. The headline was just the match. The pool was the fuel. Once those orders were consumed and the news proved false, there was nothing above to keep price up — so it fell straight back through the space it came from.
The move told researchers something real, though: it revealed how much fuel was sitting above the highs. When the actual approval came in January 2024, the market had already shown you where the orders lived.
How RIX Intel uses this signal
Before any setup, the desk asks two questions: where is the obvious pool, and has it been raided yet?
Untouched obvious levels get treated with suspicion — they're targets. The desk's preferred entries come after a sweep, not before it: a level that's been raided and reclaimed has proven there was real demand behind it, and the fuel that could have blown through it is already spent.
Invalidations are placed beyond the pool, never inside it — because a stop inside the pool isn't protection, it's a donation. You'll see this logic written into the recorded invalidation of Journal setups.
Common mistakes
Where this signal ruins people
Placing your stop just under the obvious low. That's the exact center of the pool. Either place your invalidation beyond the whole zone — with smaller size to keep the risk the same — or accept that you're first in line to be fuel.
Calling every loss a "stop hunt." Sometimes the breakdown is real, and the market is telling you you're wrong. The reclaim is the referee: no reclaim, no conspiracy — just a losing trade.
Buying the first touch of support everyone can see. Obvious levels usually get swept before they hold. Patient traders let the raid happen, then act on the reclaim.
Reacting to the wick instead of the close. A scary wick means nothing by itself. Wait for the candle to close and see where price *settled*. The close is the market's actual opinion.
