With experience in developing browser extensions and web apps, I understand your need for a paper trading platform for Indian stock market traders that integrates seamlessly with existing terminals. My past projects in creating browser extensions align well with the lightweight overlay panel concept you envision. Could you share more about the specific trading functionalities and data sources required for this platform? Regards, Yogesh Kumar

@NEHABHAT92

With a solid 9+ years of experience as a web developer & Mobile App developer, and a strong background in JavaScript, MySQL, PHP, I'm confident that I'll be able to tackle this exciting project for you. Oh btw Neha here! I not only bring technical expertise but also offer a good pulse on the market, which is crucial for building any Trading platform, let alone one that provides simulated trading. This ensures that both you and your users receive a product that not only meets expectations, but also anticipate needs before they arise! Your project requires skills within several domains ranging from integration of various APIs and platforms, real-time data processing and visualization, administering large volumes of data securely. Over my journey in technology I've honed all these skills. For example utilizing Modern AI tools such as Cursor, Claude Code and Copilot for efficient coding. But beyond skills and overused jargons like 'AI' or 'Blockchain' , what really sets me apart is the keen sense of user psychology that 9 years have given me. Trading is all about timing and emotions. I understand the adrenaline rush when the numbers go your way or the anxiety when it's against you. With this empathy, I aim to create an intuitive platform providing comprehensive features like P&L calculation based on simulated brokerage to Kafka backend implemented for efficient task distribution etc

@arshig8

Hi, I’ve carefully gone through your requirements and understand the vision behind your paper trading platform. I can build the Chrome Extension (Manifest V3), web dashboard, and admin panel with a scalable architecture, including simulated order execution, portfolio tracking, analytics, option strategies, leaderboards, and secure user management. The focus will be on clean code, fast performance, and future scalability. A few questions: Which backend stack do you prefer (Node.js, Laravel, or another)? Do you already have a market data API in mind, or should I recommend one? Will this be a subscription-based platform from the first release? Let’s discuss the workflow in chat and proceed with the next steps. Best Regards, Arshiya

@hoangvanp

Hello, Creating a paper trading platform for Indian stock market traders involves overlaying a simulated trading panel on existing terminals like Zerodha Kite and TradingView. This approach ensures a seamless user experience without the need to build a new charting product. I would start by reviewing the architecture of these terminals to ensure smooth integration. For the browser extension, I would focus on auto-detecting stock/index tickers, implementing different trading modes, and incorporating a position-sizing calculator. The web dashboard would display live positions, P&L calculations, trade highlights, and a trade journal. Additionally, the admin portal would provide an overview of users, trade logs, and subscription tracking. Having worked on similar projects involving financial data management and user interfaces, I understand the importance of accuracy and user-friendly design in this domain. Best regards,

@alluankit01

Hi, I can build your paper trading SaaS with Chrome extension, web dashboard, admin portal, simulated orders, analytics, and Indian market-specific trading workflows. The best solution is to first define a strong MVP around extension-based ticker/price detection, floating trade panel, simulated order placement, user capital system, dashboard, P&L tracking, brokerage/charges logic, and admin management. Then I’ll expand into option strategy baskets, journal, reports, leaderboard, alerts, and subscription/payment tracking in clean modules. I’m comfortable with JavaScript, Chrome Manifest V3 extensions, content scripts, DOM detection, full-stack web apps, REST APIs, MySQL/PostgreSQL, SaaS dashboards, authentication, admin panels, analytics, trade logs, PDF/CSV exports, and AI-assisted fast development workflows. Deliverables will include: * Chrome extension overlay * Simulated buy/sell order flow * User login and virtual capital * Web trading dashboard * Order book and P&L reports * Brokerage/tax charge calculation * Trade journal and exports * Admin portal * User/session management * Payment webhook support * Source code and deployment guide I’ll focus on building a clean, scalable V1 that works reliably for simulated trading and can be extended later with more analytics, options tools, and market integrations. Best regards Ankit

The make-or-break decision here is where the live price comes from, and most bids will get it wrong. The obvious approach is to scrape both ticker and price out of Kite/Dhan/TradingView's DOM. That works about two weeks. Those terminals ship obfuscated, build-hashed class names and re-render on every deploy, so a DOM-read price silently breaks and users start filling paper trades at stale prices without knowing it. What I would build instead: the content script reads only the SYMBOL (from the URL/instrument header, the most stable thing on the page), and the LTP comes from an independent market-data feed keyed to that symbol. Price integrity stops depending on someone else's frontend. Each terminal gets a small adapter for symbol detection, so when one changes you patch one file, not the fill engine. Second decision: store an append-only order/fill ledger and derive positions and P&L from it, rather than mutating a balance row. Multi-leg baskets, capital resets, brokerage/STT/stamp/GST netting and the payoff graph all become replayable instead of corruptible. Timeline: extension + fill engine + dashboard + admin + options basket builder with Greeks is not a 3-day build and I won't pretend it is. 21 days, delivered in working phases - extension and paper-fill engine first so you can trade on it early, then dashboard analytics, then admin and strategy builder. Full source, deployment, and setup docs included. Aakaash

Reading live ticker and price data purely from the DOM across four different broker terminals is really where this build gets fragile, each platform's page structure changes without notice, so the extraction layer needs to be resilient and easy to patch per-terminal rather than one brittle shared parser. I've built the Kununu scraper and IQRAi, both involved close DOM-level extraction work and structured data syncing between a browser layer and a backend system. Similar work here https://www.freelancer.pk/u/UmairBuildsAI I'd build the Chrome extension in Manifest V3 with terminal-specific content scripts for Kite, Dhan, TradingView, and Upstox, sync simulated orders instantly to a web dashboard tracking P&L with accurate brokerage, STT, and GST calculations, implement the options strategy builder with a payoff graph and refreshed Greeks, and build the admin portal for user, ledger, and subscription oversight, structuring the whole system to stay maintainable as terminal layouts shift over time. Let's connect on a call and discuss. Best Regards, Umair

@teresaa47

Hi, My background is in financial and data analysis rather than full-stack software development, so I would not position myself as the developer for your entire platform. However, I can support the financial analytics and business-analysis side of the project if you are open to separating that portion of the work. I have 10+ years of finance and data experience and an MBA in Finance & Project Management. I can help define and validate the financial calculations and reporting requirements for P&L, trading performance, KPI dashboards, return metrics, data structures, reconciliation, reporting logic, and user/admin analytics. I can also help translate the business requirements into clear specifications for the development team and test the outputs for accuracy. If you are looking for support specifically on the financial data, analytics, reporting, or business-requirements portion of the platform, I would be happy to discuss the scope.

@ExactSpec

Likely business objective: ship a lightweight paper-trading product that overlays existing Indian retail terminals (Kite, TradingView, Upstox, Dhan) so users simulate trades in the interfaces they already use, with synced analytics and an owner-only admin panel for account & ledger control. Understanding: the core technical risk is reliable DOM/price detection across third-party UIs and the legal/ToS implications of overlaying behavior. You also need accurate simulated P&L (fees, taxes, simulated margin, basic Greeks) and fast sync to a web dashboard and admin portal. The listing is well-scoped but lacks data-source and compliance constraints needed to finalize design. Recommended approach: deliver in three validated phases — 1) discovery & architecture (data sources, TOS/legal checklist, option-chain provider decision), 2) MVP extension + backend + dashboard for equity & simple options (single-leg orders, simulated P&L, account/ledger flows), 3) options strategy builder, multi-leg execution simulation, admin portal features and hardening. Each phase concludes with an acceptance-ready deployment and a lightweight runbook for maintenance. Approved ExactSpec capability: ExactSpec Electronics LLC d/b/a ExactSpec Capital Partners provides Private Equity Advisory, M&A, Due Diligence, and Custom Software & SaaS Development Oversight; we have prior development collaboration experience noted in the CellularPort Buyback Platform and Innovation36T Platform Collaboration case study entries (see provided company facts). SEAN REVIEW REQUIRED next to any assumptions about third-party terminal stability or legal permissibility of DOM overlays. Delivery stages and milestones are below. I propose fixed-price milestones with staged acceptance to limit risk and show progress quickly. Price: INR 142,748.38 (fixed-price, payable across milestones as below). SEAN REVIEW REQUIRED — recommend confirming client budget and willingness to pay published amount before starting discovery. Focused questions: 1) Do you have an approved market-data provider or are you expecting initial DOM scraping only? (license costs may be required.) 2) Have you validated that overlaying UI/reading DOM on target terminals complies with each provider's Terms of Service? Next step: confirm budget and answer the two questions above; I will kick off a 1-week paid discovery to produce a final technical spec, a risk register (including legal/data licensing), and a launch plan.

@DeanSaliegh

I can help you create an intuitive paper trading platform that seamlessly integrates with popular trading terminals. The idea of overlaying a simulated trading panel directly on existing interfaces is brilliant and will provide users with a familiar experience. My approach would involve developing a robust Chrome extension that auto-detects tickers while ensuring a smooth user experience with features like position-sizing calculators and a user-friendly web dashboard. I have done similar work: Modern Real Estate Investment Website ([Link]). My focus is on building a clean, functional design that enhances usability without overwhelming the user. Let's chat about your vision and how we can bring this project to life. You'll get a free consultation to explore the best approach. Regards, Dean
