TRADING SUITE

One risk view across accounts

Browser dashboard that pulls Hyperliquid and MetaTrader logs into one book: PnL, open positions, a closed-trade log, and APT / ICAPM risk columns. Live prices are routed by venue, and dashboard state is shared over a WebSocket so a refresh does not wipe the book.

5 pages4 venuesWebSocket sync

Problem: Fills and open risk lived in separate Hyperliquid and MetaTrader logs, so total exposure was not in one place.
Architecture: An Express API routes each symbol to the right venue. Sigma and correlation use 60 daily closes. Positions and the trade log persist on the server and broadcast over WebSocket.
Shipped: Overview, positions, trade log, APT/ICAPM, model parameters, and CSV import. A refresh keeps the same book.
