OI Surge — Signal Playbook

What it detects

Open interest jumps sharply alongside a one-sided book — fresh leveraged positions are piling into a move. New money is committing in the book’s direction.

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

How VYX surfaces it

VYX evaluates OI Surge live on every candle across 300+ Hyperliquid markets and paints it onto the heatmap, so an unusual positioning 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 OI Surge 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:

• Rising OI + rising price = new longs (conviction); rising OI + falling price = new shorts.
• A surge confirms a move has fuel behind it — but that same fuel becomes squeeze risk.
• Use with funding: surging OI into already-stretched funding is a late, fragile move.
• Falling OI on a move (not this signal) means an unwind, not new conviction.

Confirmation

What strengthens the read:

• Price trends in the book’s direction as OI builds.
• Funding moves toward the crowded side.
• Aggressive flow agrees.

Invalidation

What kills it:

• OI rolls over (positions unwinding) — the fuel is leaving.
• Price reverses while OI keeps rising (trapped positions → squeeze).

Risk & honest evidence

Respect the limits:

• New leverage cuts both ways — it powers trends and fuels violent squeezes.
• Late-stage OI surges into stretched funding are the riskiest.
• Evidence: grounded in market-microstructure research; on open-interest dynamics; needs multi-day data to validate. VYX's own live backtest is still accruing — treat this as scanner context, not a proven edge.
