Paper Trading Web & Android App

@kamran2012

Good to see this project, I will build the paper trading platform with React on web, React Native for Android, and a FastAPI backend on PostgreSQL. The app will cover auth, real-time stock dashboard, instant buy/sell simulation with a virtual wallet, and a portfolio view with P&L tracking and candlestick charts. For the market data feed, I recommend starting with Yahoo Finance via the yfinance library for historical and near-real-time data — it is free and reliable for paper trading. For live price updates on the dashboard, I will use WebSockets so prices refresh automatically without polling. Questions: 1) Which market are you targeting — NSE/BSE Indian equities, US stocks, or both? 2) Do you want a predefined list of tradeable symbols, or should users be able to search and add any ticker? Looking forward to potentially working together. Thanks, Kamran

Hello, this kind of app feels simple on the surface, but the moment trades and live prices don’t behave exactly as expected, users lose trust fast. I’d keep the core loop very tight. Prices update cleanly, orders execute instantly, and the portfolio reflects changes without delay. That part has to feel real, even if it’s paper trading. The buy/sell flow would be handled like a real system. Orders hit the backend, wallet updates immediately, and everything is stored properly so history and P&L stay consistent. On the frontend, I’d keep it close to what users are already used to. Clean dashboard, simple charts, quick switching between watchlist and portfolio. No extra layers. React for web and Flutter for Android makes sense here so logic stays shared and maintenance is easier. I’d build this in parts. First auth and basic dashboard, then trading logic, then charts and polish. That keeps things stable as it grows. Have you thought about whether you want simulated order types later like limit or stop, or just market orders for now?

Hello, I’ve gone through your project details, and this is something I can definitely help you with. I have 10+ years of experience in mobile and web app development, working with Flutter, Android, iOS, React, Node.js, and APIs. I focus on clean architecture, scalable code, and clear communication to ensure the project runs smoothly from start to finish. To align with your requirements, I suggest using React for the web front-end and React Native for the Android build, as it promotes code reusability. For the backend, Node.js with Express or FastAPI would be optimal for performance and ease of development. I can also recommend reliable APIs for real-time stock feeds. Here is my portfolio: https://www.freelancer.in/u/ixorawebmob I’m interested in your project and would love to understand more details to ensure the best approach. Could you clarify: 1.

I have read your job post and understand that you want a lightweight, fully functional paper trading platform for beginners, with both web (React) and Android (React Native) builds, real-time stock simulation, and portfolio tracking all with no financial risk. This setup ensures a realistic, zero-risk trading experience, fast UI, persistent backend, and cross-platform consistency. I can also advise on scalable, low-cost APIs to provide reliable live market data for the simulation.

@nadeemkhan7

Hello, I went through your project description and it seems like that I am a great fit for this job. I have an expert team with many years of experience in Python, NoSQL Couch & Mongo, Node.js, PostgreSQL, AngularJS, Web Development, React Native, FastAPI. Lets connect in chat so that we discuss further. Thank You

@Shrutibimpl

Hello, I will build your paper trading platform using React for the web interface and React Native to create the Android application, sharing the core business logic across both. For the backend, I will implement a robust API using Node or Python connected to a Postgres database to manage user accounts, virtual wallets, and trade history. I will integrate a popular low-cost financial data API to provide the real-time stock feed and use a standard charting library for the portfolio visualizations. The system will feature secure authentication and a responsive layout to ensure a smooth experience on all devices. This architecture allows users to practice trading in a risk-free environment that mirrors professional platforms. 1) Which backend technology do you prefer: Node or Python? 2) Are you targeting specific markets like Indian equities or US stocks? 3) Do you want the stock data to be strictly real-time or is a slight delay acceptable for this phase? Thanks, Bharat

@RajAbhisek

Hi, I have 7 years of experience building web and mobile apps. I have worked on fintech projects before so I understand how trading dashboards should feel — fast, clean, and easy to use even for beginners. Here is what I will use for your project: - React for web and React Native for Android so most of the code is shared - NestJS on the backend with PostgreSQL for storing trades, positions, and wallet data - For live stock prices I suggest we start with Angel One SmartAPI since it is free and covers Indian markets properly. I will connect it via WebSocket so prices update automatically without any page refresh For the features you asked — login with email and password, buy/sell simulation with virtual cash, portfolio view with P&L, and candlestick charts — I have built similar things before and I know the exact flow. Security is handled properly — passwords are hashed, JWT tokens are used, and rate limiting is in place on login routes. Deployment will be on Railway for the backend and Vercel for the web app. Android APK will be built using Expo EAS. I will also give you a clean README so you can run the project yourself and add new stock symbols later without any help. Happy to jump on a quick call to discuss timeline and any questions you have. Thanks, Raj

@fatimamahsud1

This is a great idea, and I can build a fast, realistic paper-trading platform that feels like Zerodha Kite or Upstox while staying completely risk-free for beginners. I’d recommend React (Web) + React Native (Android) for shared UI logic, with a Node.js (NestJS) + PostgreSQL backend for real-time performance and scalability. I’ll integrate a reliable market data provider (such as Polygon, Twelve Data, or Alpha Vantage depending on your region and budget), implement instant buy/sell simulation, live dashboard updates via WebSockets, and a secure authentication system with hashed passwords and rate limiting. You’ll receive clean source code, deployed web app, signed Android APK, and clear setup documentation so you can easily extend symbols or features later. I focus on performance, clean UX, and production-ready architecture, happy to discuss timelines and the best data API for your use case.
