Liquidity withdrawal: what the thinning looks like in the minutes before
Posted: Sun Nov 01, 2026 12:02 am
Before a major event, the market doesn't suddenly go quiet. It thins in steps, and the steps can be seen if someone is watching.
First, large resting orders disappear. Quotes at the top of the book shrink in size. Then spreads widen slightly. Then the tick rate drops, as providers update less often. In the final seconds, quotes may blink in and out.
On the chart, the market appears calm. Ranges shrink in the last minutes before the release. It's easy to read as stability. In fact, it's a market holding its breath with a very thin cushion underneath.
Anyone entering a position in this window with a normal-sized stop is placing it into a market where a small order moves price more than it would normally. The first print after the release can jump over the stop with no trading in between.
A few clues help recognize it: unusually low tick counts, a stuck spread that suddenly changes, and flat price action that doesn't match the typical noise level for the hour.
It helps to measure thinning directly. Plot the tick count per second in the five minutes before a series of releases. Most pairs show the count falling steadily as the event nears. The slope of the decline and the depth of the lull vary by pair and by release.
Another measure is the spread's volatility, not its level. In the last minute, the spread may oscillate between narrow and wide as providers adjust. A stable spread that suddenly begins to jump around signals the transition.
In practice, many scalpers set a hard cutoff, such as five minutes before any major release. Trades already open are managed, new entries are blocked. The cutoff comes from watching how early the quiet becomes unreliable.
The rule is not about predicting direction. It's about avoiding the worst conditions for fills.
How long before major releases does the market start to feel thin on the platform used?
