project: Convert Existing Polymarket Copy Trading Bot into a High-Performance Local Web Application $10-$20 MAX. Do not bid if you do not understand. Period! I already have a functional Polymarket copy trading bot running locally on my Windows PC. The trading logic is largely complete and working. This is NOT a project to build a bot from scratch. The objective is to migrate the existing application into a professional local web application that runs in my browser (localhost) while maintaining or improving all existing functionality. The current application has occasional issues such as UI stalls, delayed updates, outdated prices, and information that does not refresh correctly. These issues must be completely eliminated. The finished application should feel as responsive and reliable as a professional trading platform. Requirements: • Convert the existing standalone application into a local browser-based web application. • Maintain all current trading functionality. • Preserve the existing copy trading logic. • Create a smooth, responsive, and professional user interface. • Eliminate UI freezing, stalling, delayed updates, and synchronization issues. • All market data must update in real time. • Current copied market prices must always match the live Polymarket prices. • Individual trade profit/loss must update continuously in real time. • Portfolio profit/loss must update automatically. • Wallet balance must refresh automatically. • Position status must refresh automatically. • Order status must refresh automatically. • Active trades must always remain synchronized with the exchange. • Display all open positions, completed trades, pending orders, and trade history accurately. • Countdown timers for market expiration should update every second. • Paper trading mode should automatically clear previous simulated trades when starting a new testing session (unless restoring a saved session is intentionally enabled). • Use asynchronous programming and WebSockets where appropriate to provide seamless live updates without requiring manual refreshes. • The interface must remain responsive during heavy market activity. Security Requirements: • The application will automatically connect to my Trust Wallet using my wallet secret/private key that will be securely stored locally. • Sensitive credentials must never be exposed in the frontend. • Follow secure coding practices for credential storage and communication. Preferred Technology: • Python • FastAPI (preferred) • React (preferred) • WebSockets • Async programming • Modern responsive UI Please describe: • Your experience converting desktop applications into browser-based applications. • Your experience with real-time financial dashboards. • Your experience with WebSockets and asynchronous Python applications. • Any experience with Polymarket, prediction markets, cryptocurrency wallets, or copy trading systems. This project is focused on stability, speed, accuracy, and a seamless user experience. I am looking for a developer who can deliver a polished, production-quality local web application from my existing working bot rather than rebuilding the entire system.

I’ve converted several Python-based trading tools into FastAPI/React web apps with WebSocket live feeds, so this is straightforward. I’ll extract the bot’s core logic into a FastAPI backend, keep the copy-trading engine intact, and expose it via REST/WebSocket. React will mount a real-time dashboard with async state updates—no UI stalls, no price lag. Wallet secrets stay in backend env vars; Trust Wallet connects via secure local IPC. I’ll validate sync on Polymarket’s REST/WebSocket endpoints, add one-second countdowns, and clear paper trades on new sessions. Thanks, Andrii

Hi, I understand you’re not looking for a rebuild, you need your working Polymarket copy trading bot turned into a fast, reliable localhost web app with the same logic and smoother live updates. The main challenge is keeping every part in sync: prices, P/L, wallet balance, orders, and trade history without UI stalls. I’ve worked with Python and FastAPI-style backends, real-time dashboards, async workflows, and WebSockets, and I’m comfortable moving desktop-style logic into a browser app. I’d keep the trading engine intact, separate the UI cleanly, and wire updates through an event-driven layer so the frontend stays responsive even during heavy market activity. I’d also make sure sensitive wallet credentials stay local and never reach the browser. If you’d like, I can help turn the current bot into a polished local trading interface. Best regards, Gabriel

Hello, converting a Polymarket trading bot into a web app is mostly an architecture problem around control, state, and observability, and I’ve built production systems where a backend engine had to be exposed safely through a user-facing interface using FastAPI. The real engineering risk is not the UI itself; it’s keeping trading state, execution flow, and operator actions consistent so the web layer cannot create duplicate orders, stale decisions, or unclear bot behavior. The closest match is Enterprise ProxyTool Client App, where I separated a real-time execution layer from the control plane and API surface. DocIntel AI is also relevant for FastAPI service design, background processing, and turning a complex backend workflow into a manageable web application. I usually structure this as distinct layers: strategy/execution, state tracking, and web control. That keeps the trading engine deterministic while the app handles auth, settings, logs, positions, and manual overrides without coupling UI requests to execution timing. For systems like this, I also add audit trails, idempotent action handling, and clear failure visibility so bot decisions and order outcomes can be inspected after the fact. If useful, I can sketch the service boundaries and operator flow for the bot-to-web-app upgrade before implementation. Clifton

Hello! Transforming your Polymarket copy trading bot into a high-performance local web application requires solid software architecture and full-stack development expertise to ensure speed, reliability, and seamless user experience. I've built web applications using Python, JavaScript, PHP, and HTML that handle real-time data workflows and complex backend logic. My software architecture background ensures the system is modular, maintainable, and optimized for local deployment. I've designed interfaces and APIs that integrate trading logic with responsive frontends, so users get instant feedback and control over their strategies. Here's how I'll deliver this upgrade: - Refactor the existing bot logic into a clean backend service that handles copy trading operations efficiently - Build a responsive web interface using JavaScript and HTML that provides real-time monitoring and configuration controls - Architect the system for local deployment with secure data handling and minimal latency What specific features or controls do you want prioritized in the web interface beyond monitoring trades and adjusting settings? I'm ready to start immediately and can share a detailed technical plan after we discuss your current bot structure and desired functionality. Let's connect via Freelancer messages to review the codebase and finalize the architecture. Best regards, Jordan Rafael G.

Hello, "FastAPI + React Real‑Time Trading UI" - migrate desktop bot to a responsive local web app. I will wrap your existing Python trading logic in a FastAPI service and build a React front‑end that uses WebSockets for live price and order updates. FastAPI’s async support ensures low latency, while React gives a smooth UI. I automated a similar Python‑based backup with a web interface: https://www.freelancer.com/projects/automation/Automate-Reolink-Video-Backup-Script/reviews. To keep your Trust Wallet secret safe, the key will be stored only on the backend and never exposed to the browser; all credential handling follows secure coding best practices. Could you share how the current trading logic is organized (e.g., main classes or functions) and whether it already uses any async calls? Looking forward to working with you. Artur Giżycki
