5-Minute Markets
Fast short-duration structure
Monitor 5-minute crypto up or down contracts with a clean trading view that keeps price, strike, execution, and account context on one screen.
15-Minute Cross-Platform Markets
Compare Polymarket and Kalshi in one workflow
Watch equivalent 15-minute markets side by side, compare the price to beat, and route into the better setup without losing time to context switching.
XARB Depth Dashboard
A broader view of market depth
Watch order-book depth across venues in one place and find ideas by observing pressure, imbalance, and structure before a trade is placed.

Capital Mobility
Move funds where the trade is
Funding tools keep capital flexible across venues so you can respond to what the market is offering. Transfers average around 30 seconds, while fresh users can sometimes take longer.
