Stop Hunting Explained: What a Stop Hunt Is, Why It Happens, and How to Trade It

A stop hunt is a fast, short-lived move through a price level where stop-loss orders are clustered, followed by a reversal. It happens on every liquid market at every timeframe, typically at session opens, and is the recurring mechanic that explains why price so often moves against you before going where you expected.

You place a long. You put your stop a few pips under the obvious low, because that is where "the trade is wrong." Price drifts down, spikes through the low by exactly enough to fill your stop, and then rallies 80 pips without you.

That is a stop hunt. It is one of the most consistent patterns in every liquid market, and understanding it changes where you enter, where you place risk, and which move of the day you trade.

What a stop hunt is

A stop hunt (also called a stop run, liquidity grab, liquidity sweep, purge, or raid) is a sharp, short-lived move through a price level where a large number of stop-loss and breakout orders are resting, followed by a reversal. Its purpose (or effect, depending on who you ask) is to fill those orders at the extreme, giving whoever is on the other side a large position at the best price of the session.

Three features identify it:

• Location. It targets obvious levels: the previous day's high or low, the Asian-session range, equal highs/lows, round numbers.
• Speed. It is fast, one to three candles, because the orders it triggers are market orders that execute instantly.
• Failure. Price does not hold beyond the level. It closes back inside the range, usually within a few candles, and then moves the other way.

Why stops are so easy to find

Most traders put stops in the same place: a few pips beyond the most recent swing, or just past a round number. You do not need inside information to know where they sit.

That is not folklore. Carol Osler's research at the Federal Reserve Bank of New York, using thousands of real customer orders from a major dealing bank, found that take-profit orders cluster at round numbers while stop-loss orders cluster just beyond them, and that exchange rates move faster and further after reaching a stop-loss cluster than after any other type of level. Stops are, quite literally, fuel: each one that triggers is a market order pushing price into the next one. A cascade.

Anyone with an order book can see the cluster. Anyone with enough size can reach it.

Who actually runs the stops

This is where most articles either sell you a conspiracy or dismiss the whole idea. The honest answer sits in between.

Retail brokers (A-book): a regulated broker that passes your order to the market has no incentive to hunt a 0.2-lot stop. They earn the spread either way. The "my broker spiked the price to hit my stop" complaint is usually noise on a low timeframe.

B-book brokers and CFD "synthetic" pricing: a broker that takes the other side of your trade does see your stop and does control the feed. This is the one case where the broker can literally be the hunter, which is one reason to know how your broker handles your orders.

Market makers and large dealers: in the interbank market, the institutions that provide liquidity know where order flow clusters and are paid to position ahead of it. Whether you call that manipulation or inventory management, the stop cluster gets run, and the move that follows is the one they positioned for.

The illegal versions, specifically spoofing (placing orders you intend to cancel, as in the Sarao Flash Crash case and JPMorgan's $920M precious-metals settlement) and benchmark-fix collusion (the 2014 to 2015 "Cartel" chat-room fines), are real and prosecuted. Trading toward a level where stops sit is not illegal. That distinction matters: the stop hunt you see on a chart every session is a structural feature of how liquidity works, not a crime you can report.

Is stop hunting illegal?

Trading into a level where stop orders cluster is legal. Spoofing (placing fake orders to move price) and collusion to fix a benchmark rate are illegal and have resulted in significant fines and criminal charges. The stop hunt you see on a retail chart every session falls into the legal category.

Stop hunt vs. liquidity sweep vs. liquidity grab

These terms describe the same event from different schools of thought.

Use whichever vocabulary your charts use. The trade is identical. (See Liquidity sweeps explained and Liquidity grabs explained.)

Where stop hunts fit in the market maker cycle

A stop hunt is phase two of the market maker cycle: accumulation (quiet range), then manipulation (stop hunt), then the real trend. It is the bridge between the quiet range where a position is built and the directional move that pays for it. That is why the hunt so reliably happens at session opens (London at 3:00 am ET, New York at 9:30 am ET), when there is finally enough liquidity to fill size.

In forex the classic setup is the Asian range: price consolidates overnight in a 30 to 50 pip box, London opens, price spikes 25 to 50 pips through one side, then reverses and trends the other way for the rest of the session.

How to trade a stop hunt instead of being one

1. Don't trade the first move. The first fast move of a session is far more often the hunt than the trend. Wait for the reversal.

2. Enter on the reclaim. The signal is a close back inside the range after the spike, not the spike itself. A two-candle reversal at the extreme (a long wick, or railroad tracks) is the classic trigger.

3. Place stops beyond the hunt, not beyond the range. If your stop is where everyone's stop is, it is part of the liquidity. Beyond the spike's extreme is a different place than beyond the range.

4. Trade in the direction of the higher-timeframe trend. A stop hunt against the daily trend is an entry. A stop hunt with the daily trend is usually the start of a bigger reversal. Know which one you are looking at before you click.

5. Size for the spike. Wider stop, smaller position. The math of avoiding the hunt is worth far more than the extra pips of a tight stop.

How TrendTrader Pro handles it

TrendTrader Pro's engine does not fire on the spike. Its signals mark the point where a brand-new directional trend is established, and they flip when that trend ends. A stop hunt shows up as noise inside an existing signal rather than a new one. That design keeps you in the real move and out of the manipulation.

If you want to see the signals in action, you can review the pricing and plan options or browse the TrendTrader blog for more on how the engine works.

FAQ

Is stop hunting illegal?

Trading into a level where stop orders cluster is legal. Spoofing (fake orders) and collusion to move a benchmark are illegal and prosecuted. The stop hunt you see on the chart every session is the legal kind.

Do brokers hunt stop losses?

An A-book broker passing your order to the market has no way or reason to. A B-book broker that takes the other side of your trade can see your stop and controls the price feed, which is why broker choice matters.

How do I know if a move was a stop hunt?

It broke an obvious level fast, failed to hold beyond it, and closed back inside the range within a few candles, then went the other way.

Where should I put my stop to avoid being hunted?

Beyond the manipulation extreme, not just beyond the range everyone else can see. And if that makes the stop too wide, reduce size rather than tightening it.

What is the difference between a stop hunt and a liquidity sweep?

None in practice. "Stop hunt" names the intent; "liquidity sweep" names the footprint. Same event, same trade.
