Stock Trading Platform
A trading interface with live quote streaming and position analytics, built to learn real-time data handling in React.
The problem
An exercise in handling a high-frequency data stream in a UI without the render cost collapsing as the number of watched symbols grows.
What I built
- Streamed quote updates into a normalized store and rendered from derived selectors rather than re-rendering the whole tree per tick.
Where it landed
- Working buy/sell flow against simulated positions with live analytics.
