Spikes: hunting for liquidity

A spike is a sharp burst of price in one direction followed by an equally fast return. The chart draws a wick: price shot up, say, a couple of percent in a second or two and almost immediately came back to where it started. In market language this is a liquidity sweep — and there's almost always something deliberate behind it.

What a liquidity sweep is

Stop orders always pile up beneath the obvious levels. Below a local low sit the stops of everyone who's long. Above a local high, the stops of the shorts. These clusters are visible to anyone who can read a chart — which means they're visible to big money too.

A stop is, at its core, a market order that triggers automatically. When price reaches a cluster of stops, they cascade into execution and, for a moment, create a powerful one-directional flow of liquidity. That liquidity is the target. A large participant who needs to fill or unload serious size finds it convenient to do so at the exact moment the market hands them counterparties. Price is "spiked" up to the cluster, the stops trigger, the size gets absorbed — and price comes back, because there was no genuine interest in continuing the move.

Why a fast return is so informative

The key here isn't the burst itself — it's the return. If price shot away and didn't come back, that's most likely a real move: news landed, a level broke, a trend began. But if it lunged and almost immediately retraced more than halfway, that's a completely different story.

A fast return means the move had no foundation. The impulse found no follow-through, nobody picked price up at the new level, and it collapsed back. That retrace is direct evidence the burst was technical: someone swept the liquidity and left. A false breakout, swept stops, a wick on the chart — three names for the same event.

That's why a spike-with-return is more informative than a plain volatility burst. It doesn't just say "there was a move" — it says "the move was empty," and an empty move is almost always someone's intent.

Speed is power, drift is noise

There's a subtlety that separates a real spike from ordinary market fidget: speed.

A fast burst — over a second or two — is power. Behind a move like that is concentrated action: someone's large order or a cascade of stops that happened right here, right now. A slow drift covering the same couple of percent over ten seconds is just volatility, ordinary price wandering you can't squeeze any conclusion out of.

So we look not only at amplitude but at how fast the spike developed. Sharp, snapping moves pass the filter; slow drifts are screened out as noise. We keep the windows tight — a short allowance for the burst and a short one for the return — because a spike is by definition a fast event, and anything that drags out isn't one.

Reading it alongside walls

A spike gets far more eloquent in combination with other signals — especially walls.

Picture this: a large wall is resting in the book, and then price makes a sharp spike right toward it and returns. That's no longer a lone wick but a coherent story: someone may have been deliberately clearing liquidity around a prominent level. Or the opposite — the spike ran through a zone where there were no walls at all, which tells you something different.

No signal works in a vacuum. A wall shows where the big money is standing. A spike shows the moment someone came for the liquidity. Together they form a picture of what's happening far more complete than either one alone.

And, as always, we show the event, not a recommendation. Here's the spike: this many percent, in this many seconds, with this much return. What it means for your position is up to you. Our job is to catch it before it dissolves into the tape and put the fact on your desk.
