Better Trade Journey

We designed and built Better Trade Journey as a TypeScript monorepo on Turborepo, keeping the domain logic apart from the UI so the calculations that matter most can be tested on their own.

• MT5 import pipeline — parsers for MT5 HTML and XLSX reports that detect the file type, handle UTF-16 encoded exports and map broker-specific column layouts. Parsing and saving run as BullMQ jobs on Redis in a dedicated worker, so large uploads never slow down the web app.
• Analytics engine — a standalone, unit-tested package that computes net P&L, win rate, average R:R, profit factor, cumulative P&L and drawdown curves, breakdowns by weekday, hour, trading session and holding time, and a risk-of-ruin simulation.
• Fast dashboards — a daily-stats rollup is recalculated after every import, so the P&L calendar loads instantly instead of re-scanning every trade.
• Journal and strategies — trade notes, tags, screenshots and strategy playbooks with statistics for each strategy.
• Admin console — user management, a parser error log showing the broker, file and error for every failed import, broker presets for column mapping, a global symbol directory, and an audit trail of admin actions.

The app runs on the Next.js 15 App Router with a type-safe tRPC API and Drizzle ORM over PostgreSQL, and is covered by Vitest unit tests and Playwright end-to-end tests.
