Trading Companion, Discipline System for Retail Traders

Problem

Retail and semi-professional traders lacked an all-in-one discipline system for position sizing, risk management, trade planning, and journaling. Existing tools focused on signal generation but ignored the execution and psychology side of trading.

Approach

Built a full-stack trading companion from the ground up: Vite + React + TypeScript frontend with a Supabase backend, Stripe subscription billing, and PWA support for mobile use. Automated tests and monitoring ensure production reliability.

Result

One system for position sizing, risk, planning, and journaling. Traders stop switching between tools and start building consistent habits.

• ◆One system replaces four separate tools
• ◆Traders build consistent habits with automated tracking
• ◆Works on desktop and mobile with no app store dependency
• ◆Subscription revenue from day one with Stripe billing
