Multi-venue trading, one browser tab
Professional crypto trading interface. Cross-venue order books, chart overlays, algo control, P&L, and execution trace — live at terminal.sequencemkts.com.
Layout
Modular canvas workspace — arrange panels freely.
Market Data
Cross-venue order book, NBBO, charts, and time & sales.
Order Entry
Market / limit / SOR orders from a single panel.
Unlike traditional exchange UIs that show data from one venue, the Terminal aggregates order books and prices across all connected exchanges into a unified view. Built in React, connected directly to the execution engine over WebSocket and SSE.
Getting Started

Real-Time Data
The Terminal maintains a persistent WebSocket connection to the Sequence API at wss://api.sequencemkts.com/v1/ws/market_data. This provides:
- Order book updates -- L2 depth refreshed on every tick from every venue
- BBO/NBBO -- Best bid and offer computed across all exchanges in real-time
- Trade feed -- Public trades from all connected venues
- Order status -- Live status updates via Server-Sent Events (SSE)
All market data in the Terminal comes from Sequence's own aggregation layer, not from a single exchange. Prices reflect the true cross-venue best available quotes.
Browser Support
The Terminal is tested on the latest versions of Chrome, Firefox, Safari, and Edge. For the best experience, use a Chromium-based browser with hardware acceleration enabled. The canvas layout system and real-time WebSocket feeds perform best with at least 8 GB of RAM.
