Aggressive Sweep — Signal Playbook

What it detects

A burst of aggressive market orders sweeps one side of the tape (a large buy or sell run in notional) while the book already leans that way — momentum players are paying up to get filled.

How Aggressive Sweep paints across a heatmap row — the colour language it speaks on the live map.

How VYX surfaces it

VYX evaluates Aggressive Sweep live on every candle across 300+ Hyperliquid markets and paints it onto the heatmap, so an unusual flow reading stands out at a glance instead of hiding in a watchlist. That is the job it does in the workflow: it is a scan filter and a piece of context, not an automatic entry. Scan the map for where Aggressive Sweep is firing, focus that market to read the signal against price and the confirmation cues below, and let the next candle or two resolve before acting on it.

How to play it

Use it as scanner context, not an automatic entry:

• A sweep shows urgency — someone wants in now and is crossing the spread.
• Trade with the sweep’s direction on continuation, only when the book agrees.
• Best on liquid majors where a sweep means real size, not a thin-book blip.
• Pair with OFI/CVD for a higher-conviction read.

Confirmation

What strengthens the read:

• Follow-through prints in the same direction.
• Book imbalance stays on the sweep’s side (it didn’t just get absorbed).
• Spread stays orderly through the burst.

Invalidation

What kills it:

• The sweep is fully absorbed and price stalls (see Delta Absorption).
• Imbalance flips against the sweep immediately after.
• One isolated print with no follow-through.

Risk & honest evidence

Respect the limits:

• Sweeps can mark exhaustion (the last buyers) as easily as continuation.
• Chasing a sweep means paying the worst price.
• Evidence: grounded in market-microstructure research. VYX's own live backtest is still accruing — treat this as scanner context, not a proven edge.
