The project
This mobile app creates a simulated trading environment without real-money transactions. Users can sign up, manage a virtual wallet, buy and sell mock stocks, and explore how their holdings change alongside the market data.

What I built
The application combines account flows, a trading simulation, portfolio views, and price history in one Flutter experience.
Twenty mock stocks
Buy, sell, and hold stocks using a stream of mock market data.
Portfolio view
A dedicated page showing the user’s current holdings.
Interactive history
Interactive historical price charts spanning up to one year per stock.
Technical focus
BLoC-based state management organises the Flutter application as it receives and renders frequent price changes. The project description documents updates more than five times per second, along with authentication, REST APIs, and interactive charting.

Conceptual component map
Simulation, not investment performance. All balances and prices belong to a mock trading environment. The cover chart is an illustration, not a live market feed or a screenshot.
