Grotaro

The cross-platform analytics dashboard for short-duration crypto markets. Watch structure, compare venues, and stay on top of fast-moving market data in real time.

5-Minute Markets

Fast short-duration structure

Monitor fast 5-minute crypto market moves with a clean analytics view that keeps price, reference levels, and market context on one screen.

Keep short-duration markets, live pricing, and key reference data in one place.
See the price to beat clearly instead of piecing context together across tabs.
Designed for people who build their understanding by watching market behavior in real time.

15-Minute Cross-Platform Markets

Compare Polymarket and Kalshi in one workflow

Watch equivalent 15-minute markets side by side with independent reference price lines that update ahead of each venue's own data feeds, so you always know where the price stands and where it's heading.

View the Polymarket and Kalshi side together instead of separately.
An independent real-time index built from the same constituent exchanges as CF Benchmarks, the pipeline behind Kalshi's asset pricing. It updates faster than Chainlink, the oracle Polymarket relies on.
A 60T line mirrors Kalshi's 60-second average pricing, and a live spot line shows where that average is headed next.
See where venues agree, where they diverge, and where the pricing looks out of line.

XARB Depth Dashboard

A broader view of market depth

Watch order-book depth across venues in one place and build insight by observing pressure, imbalance, and structure as it develops.

Monitor multiple assets at once instead of guessing from one isolated market.
Use visible depth and divergence to sharpen your read on pressure and momentum.
Built for people who do their own analysis and want more ways to explore the data.
