SCREENER Web App

@rizwange4

Hi, I can build a modular, high-performance **web-based options screener** with a **React frontend** and a **Python (FastAPI) or Node.js backend**, integrated with the **Upstox API** for real-time option chain data. The architecture will be designed to make it easy to add new filters, switch data providers through configuration, export results to CSV, and send Telegram alerts without affecting existing functionality. The screener will feature a responsive dashboard, customizable filtering (OI, volume, IV, IVP, Greeks, expiry, etc.), real-time updates, and a clean codebase with Docker support, setup documentation, and a README showing exactly where to configure your API keys. I'm committed to delivering a fast, scalable MVP that is easy to maintain and extend. **Muhammad Rizwan LA**

Hello, I can help with your "SCREENER Web App" project. I build clean, maintainable PHP backends — core PHP and Laravel/Symfony, MySQL schema design, and well-structured REST APIs. For work involving php, javascript, python, software architecture, html, node.js, docker, web development, vue.js, api development, I pay close attention to validation, security, and readable code, delivering in small, testable milestones. I provide clean commits and clear documentation. Could we discuss the specifics before I firm up the timeline? ⭐ 5.0/5 from a recent client: "Very Professional and On time delivery of the project" Final timeline and cost will be confirmed in chat after a complete understanding and documentation of the project expectations in detail.

Greetings, Creating a flexible options screener that filters live option chains sounds like an exciting challenge. Your need for customizable filters based on various metrics is essential for quick decision-making. I would approach this by building a modular solution using a modern JavaScript framework like React for a clean interface, paired with a robust back-end possibly in Node.js. This way, we ensure quick load times and easy adaptability for future enhancements. To meet your requirements, I would integrate a reliable API for real-time data, allowing for seamless switching between providers as needed. Additionally, I’d implement features for exporting filtered results and sending alerts via Telegram, ensuring everything is user-friendly and responsive. I have successfully completed similar projects, focusing on clean code and performance. Let’s discuss how we can make this screener a powerful tool for your trading needs.

Hi, Thanks for sharing your project. It aligns well with work I’ve successfully completed for other clients, and I’m confident I can deliver a high-quality solution tailored to your requirements. Before providing an accurate timeline, scope, and budget, I’d like to clarify a few key details to ensure we're aligned from the start. Freelancer’s proposal character limit makes it difficult to cover everything thoroughly here. If you're available, let's connect via chat. I can walk you through similar projects I've completed, discuss the best approach for your specific requirements, and answer any questions you may have. Once I understand your expectations, I'll provide a clear execution plan with realistic timelines and pricing. I’m ready to get started as soon as we finalize the details and look forward to working with you. Best regards, Mayank Sahu

Microsecond-level filtering on a live option chain isn't a front-end problem — it's whether your data layer polls UPSTOX efficiently enough that filtering logic never becomes the bottleneck in the first place. I trade 5-minute charts and scalp futures myself, so I know exactly what "no buffering, no false signals" actually means when you're staring at OI and IV changes in real time — this isn't a generic dashboard brief to me. I'd build it as a Python/FastAPI backend polling UPSTOX on a websocket where available, with your scan criteria loaded from a config file so you can add metrics without touching core logic, plus Telegram alerts and CSV export as thin output layers on top. One thing that affects architecture directly: does UPSTOX give you websocket streaming for option chain data, or only REST polling — that decides whether "real-time" here means sub-second or truly push-based.

Hi, Your project immediately caught my attention because you're not looking for a basic screener you need a fast, reliable trading tool that can handle live market data, apply custom filters instantly, and remain flexible as your strategy evolves. I can build a clean, responsive options screener with a modular architecture, making it easy to add new filters, switch data providers, and maintain the project over time. The dashboard will display real-time filtered results, support CSV export, Telegram alerts, and provide the key option metrics you need, all while keeping performance and scalability as the top priority. I'd love to discuss your scanning logic, preferred tech stack, and timeline so we can build an MVP that's ready for live market testing. Best regards, Usama K

I will design and develop a flexible options screener that can rapidly filter live option chains and export results for alerts or further analysis. To achieve this, I will utilize a modular approach with a Python back-end, connecting to the UPSTOX API for market data, and a clean, responsive React front-end for user interaction. I have experience with similar projects, such as the Telegram Trade Signal Bot, where I developed a bot to parse and forward trade signals using regex-based filtering and user-specific preferences. Another relevant project is the Real Estate Data Extraction, where I engineered a sophisticated data pipeline to extract real estate tax data from dynamic websites and public APIs, handling high-volume data acquisition and complex data handling. Can you please provide more details about the scanning criteria and parameters you would like to use for filtering option contracts? Additionally, are there any specific metrics you would like to prioritize for the addition of new metrics later without rewriting the entire program?

My goal is to deliver a robust, user-friendly screener platform that supports informed decision-making and long-term scalability.

@aakaashb1

Hi! I can build your modular, high-performance options screener with a React frontend and a Node.js (or Python/FastAPI) backend. I'll integrate the Upstox API with a provider abstraction layer so switching data sources only requires a config change. The screener will support customizable filters, real-time option chain scanning, CSV export, Telegram alerts, and a responsive dashboard displaying Greeks, OI, IV, IVP, Bid/Ask, and other key metrics. The code will be clean, well-commented, Docker-ready, and include a README, setup guide, and deployment support. I can deliver an MVP quickly and refine additional filters and features based on your testing and feedback.

@CliveMSoftware

I'll build your options screener as a modular Node.js backend with React frontend, connecting directly to UPSTOX API with configurable data sources. The backend will handle real-time option chain pulls, apply your custom filter logic (IV, OI change, volume, expiry) through a plugin-style config system, and serve filtered results via REST endpoints. Frontend will display live data in a clean dashboard with instant CSV export, Telegram alert integration, and Greeks/Greeks summary display. Code will be fully commented, dockerized for easy deployment, and include a setup guide for your own API keys. I'll deploy a working demo and conduct testing with you to ensure zero false signals before handoff.
