Liquidity Is Conditional (And Often Disappears)
Why displayed liquidity constantly changes, disappears, repositions, and sometimes reveals more through absence than presence.
This post is part of our Market Depth & Liquidity series.
If you haven’t read the previous post in this series, you can find it here.
One of the more important realizations that came from watching liquidity over long periods of time was understanding how unstable it actually is.
Displayed liquidity can feel concrete.
There will be size at a level, then price approaches it….
The assumption becomes that the liquidity will participate once tested.
Sometimes it does.
But not always.
And over time, some of the more meaningful information starts coming not from the liquidity that appears, but from the liquidity that fails to remain there once interaction becomes imminent.
Resting Orders Exist Under Conditions
Every passive participant has a price where they are willing to trade.
But they also have a price where they are no longer interested in participating.
That distinction matters because resting liquidity is not a commitment to transact under all conditions. It is a willingness to participate while conditions remain acceptable.
As volatility changes, aggression increases, or positioning shifts, that willingness can disappear very quickly.
This is why the book can appear heavy moments before becoming thin.
Liquidity Often Changes Before Price Reaches It
One pattern that becomes difficult to ignore is how frequently large liquidity changes behavior before interaction even occurs.
