Competitive Advantage

Most desks react to price.
Our clients see what's about to move it.

Informed order flow is present in every significant market move — before price reacts. The question is whether your system can read it in time to act.

Without Qantis
  • You react to price — not the order flow that drives it
  • Informed traders pick off your quotes before you can adjust
  • Spreads are set manually, rarely in real time
  • CVD divergences are invisible until the move is over
  • No cross-venue signal reference — you're quoting blind
  • Every widening happens after the damage is done
With Qantis
  • VPIN flags toxic flow ~40 seconds before price adjusts
  • Informed flow detected before it fills your orders
  • Dynamic spread logic driven by real-time VPIN via API
  • CVD divergence visible at 1-minute resolution, live
  • Binance perp microstructure as cross-venue reference layer
  • OFI gives you 200–800ms of directional lead on mid-price

Signal Suite

Three signals. Computed from first principles.

Not derived from price. Not lagging indicators. Computed directly from raw tick data and order book state — before the move happens.

01 / TOXICITY
VPIN
Volume-Synchronized Probability of Informed Trading
0.712
BTC-PERP · Live · Binance

VPIN above 0.75 means informed traders are actively hitting your quotes. You have approximately 40 seconds before price moves against you. Widen spreads, reduce size, or step back entirely. The signal does not care about your position.

Methodology: Easley, López de Prado & O'Hara (2012). Volume-synchronized, not time-synchronized — 10× more responsive to informed flow than VWAP or time-bar methods.

02 / DIRECTION
CVD
Cumulative Volume Delta
+$48.2M
BTC-PERP · 1h Window · Live

CVD diverging from price means someone is accumulating or distributing without moving the market yet. That divergence closes violently — and you want to know before it closes. Rolling windows at 1m, 5m, 1h, 4h delivered simultaneously.

Computed from aggressive taker flow (buyer-initiated vs seller-initiated). Divergence from price is one of the most reproducible signals in liquid crypto markets.

03 / PRESSURE
OFI
Order Flow Imbalance
+0.68
BTC-PERP · L2 Snapshot · Live

200–800ms before the mid-price moves, the order book is already screaming. OFI captures that scream at the queue-refresh level. If you're not reading it in real time, you're the exit liquidity — every time.

Computed from Level 2 bid/ask queue refresh differentials. Asset-specific calibration. Not a proxy — direct measurement of short-term directional imbalance.

Architecture

Not a data reseller.
A computation engine.

We don't relay orderbook snapshots. We compute VPIN, CVD, and OFI in real time across 527 symbols and 12 exchanges — calibrated per asset, cross-validated across venues.

Who It's For

Built for teams where
latency and precision are P&L.

Not a retail product. Not a dashboard. An API layer for professionals who understand that microstructure signals are a structural edge — not a nice-to-have.

MM
Market Makers

You're offering liquidity into a market that has informed traders in it. VPIN tells you when they've arrived. Adjust spreads programmatically via API. Stop donating inventory.

PT
Prop Trading Firms

CVD divergence from price is one of the cleanest signals in liquid crypto. When they disagree, CVD is right first. Build directional alpha on a signal that leads price — not follows it.

QF
Quant Funds

Academically grounded, computationally rigorous, reproducible. Integrate VPIN, CVD, and OFI directly into your factor models. Historical tick data available for systematic backtesting.

XV
Cross-venue MMs

VPIN on Binance predicts price impact on Hyperliquid within 15–30 seconds. We've measured this. Use centralized perp microstructure as a real-time reference when quoting on DEX perps.

Pricing

Access the layer others don't have.

No per-request billing. No usage caps on paid tiers. Flat pricing so your models can query as aggressively as they need to.
