Options Activity Scanner & Web Dashboard

@crtvecode

1) What specific parameters do you envision for user-configurable settings, and how do you plan to manage the storage and retrieval of these presets in the database? 2) Can you clarify your preference for real-time data updates? Would you like to use websockets for continuous streaming, or do you prefer a polling mechanism based on the capabilities of the DhanHQ API? 3) How do you want to handle user authentication and role management for accessing the dashboard, especially if there are plans for multiple users with different permission levels? I commit to providing feedback and iteration updates within 12 to 24 hours, and I will make sure to keep you informed with small incremental updates throughout the development process. As a first deliverable, I can provide a draft schema for the database and the initial API skeleton within 2 to 3 days, setting a solid foundation for the project. I look forward to discussing the project further and getting started. Please feel free to message me! Rajavel

I have 8+ years of experience in web development and am familiar with modern web technologies, frameworks like API integrations and other tools. You need a live dashboard that pulls option data through the DhanHQ API, scans for unusual moves using your chosen settings, and sends in-app alerts right away. On the backend, I'll fetch data efficiently, avoid hitting rate limits, and push updates through the page without refreshing. The interface will let you change every threshold, save presets, and view the alert history with simple charts—all on desktop and tablet. I can start right away.

Your DhanHQ integration will fail during market volatility if you poll too aggressively — NSE option chains can return 500+ strikes per expiry, and naive polling will burn through rate limits in under 10 minutes. You also risk stale gamma calculations if you don't handle chain snapshots atomically. Quick questions - are you planning to track all weekly expiries simultaneously, or focus on front-month only? And do you have a DhanHQ production API key with confirmed rate limits so we can design the caching layer correctly? Here is the architectural approach: - WEBSOCKET + REDIS: Build event-driven pipeline using DhanHQ streaming where available, fall back to intelligent polling with Redis cache to keep API calls under quota while maintaining sub-second UI updates. - PARAMETER ENGINE: Create JSON-driven threshold config stored in PostgreSQL so every metric (RVOL, GEX, VEX, Gamma-Regime, IV Rank) recalculates on-the-fly when you adjust sliders — no redeployment, no downtime. - REAL-TIME ALERTING: Implement server-sent events to push breach notifications instantly to the browser with full event history, filterable by symbol, strike, and metric type. I've built similar options analytics dashboards for two prop-trading desks that process 200K strikes per second during expiry days. Let's schedule a 20-minute technical call to walk through the DhanHQ endpoint structure before locking the data model.

I can build your web-based dashboard that scans NSE and BSE option chains and alerts you to unusual activity. My first step will be to define the backend architecture to ensure efficient data fetching and real-time updates. Based in Toronto, I work promptly and stay responsive throughout the project.

@Hrolgar

Would RVOL and IV Rank recompute cleanly if you swap DhanHQ's feed for a backup source mid-session, or does that only get answered once I see the actual field mapping? That's the piece of this build I'd want nailed down early, because everything downstream, the GEX and VEX regime flags, the CE/PE walls, the gamma-flip line, is derived off whatever those two feeds hand back, and a scanner that silently degrades under a feed hiccup is worse than one that just stops. The way I'd structure this is each signal as its own calculator with its own config block rather than one big scoring pass, so RVOL's lookback window or the Dealer-Flow Score's weighting can be changed from the dashboard without touching code or redeploying. That also means presets aren't just saved filter states, they're saved parameter sets per signal, which is what you'd actually want if you're tuning this against live NSE/BSE behaviour week to week. For the numbers: 37,500 INR over 12 days, split M1 4,500/2d for the DhanHQ ingestion pipeline and the calculator framework, M2 21,000/6d for the full signal stack plus alerting and charts, M3 12,000/4d for the dashboard, login, presets and heatmaps. That's my read off the brief as written, I'd tighten it once I know how many option chains you're scanning concurrently and whether alerts need to fire on tick data or can run off a polling interval. Two things before I lock scope: do you already have a DhanHQ subscription tier that covers the option chain and market depth endpoints this needs, and are the heatmaps a live view only or do you want historical replay too.

@softhunters

This dashboard needs more than a market-data UI—the key is a reliable real-time signal engine that calculates option-chain metrics efficiently while keeping every threshold configurable from the frontend. I can build the system around a Python backend + responsive JavaScript dashboard, with DhanHQ integration structured for efficient polling/WebSocket usage according to the available API capabilities. ✅ NSE & BSE live option-chain ingestion ✅ RVOL, GEX, VEX, Charm, IV Rank/Percentile & regime calculations ✅ CE/PE walls, Gamma Flip & Dealer-Flow Score ✅ Fully configurable metric thresholds without redeployment ✅ Preset creation, editing and switching ✅ Real-time in-app alerts + searchable event history ✅ Live charts, option-chain heatmaps & summary tables ✅ Secure authentication and responsive desktop/tablet UI ✅ Caching, rate-limit protection and efficient data processing ✅ Clean architecture with logging, error handling and deployment documentation I’ll keep the scanner/alert engine separated from the presentation layer so parameter changes can be applied safely without disrupting the live feed. The architecture can also remain extensible for additional signals later. I’m Ashish Malik, Full Stack Developer & Digital Marketing Expert with 9+ years of experience and 500+ projects delivered. If you’re looking for a robust dashboard rather than a basic API visualization, let’s start a chat and discuss the implementation approach.

@Visharaa2024

Hi, This is a real-time derivatives analytics system, so I’d focus first on data reliability, calculation accuracy and alert latency rather than simply building another trading dashboard. I’d use React + TypeScript for the dashboard and Node.js + PostgreSQL + Redis for the backend. The DhanHQ integration would be isolated so polling/WebSocket behaviour can be adapted to the APIs actually available, with caching and rate-limit controls protecting the data pipeline. I’ll build: NSE/BSE option-chain scanner RVOL, GEX, VEX, Gamma/Vex Regime, Charm, CE/PE walls Gamma-flip, Dealer-Flow Score and IV Rank/Percentile calculations UI controls for every metric and threshold Saved parameter presets without redeployment Real-time charts, heatmaps and summary tables Immediate in-app alerts + searchable event history Secure authentication and responsive desktop/tablet UI Efficient data ingestion, caching and background processing Production deployment, documentation and walkthrough I’d begin by validating the DhanHQ market-data capabilities and formulas, then build the ingestion/calculation pipeline before connecting the live UI. Best regards, Deepak

@thinkbotictech

Hi, I can build a real-time DhanHQ-powered NSE/BSE options dashboard with configurable RVOL, GEX, VEX, Gamma/Vex Regime, Charm, walls, Gamma Flip, Dealer Flow, and IV metrics. I’ll deliver live alerts, charts/heatmaps, threshold presets, secure login, alert history, optimized data handling, source code, deployment guide, and walkthrough. 1. Do you already have the DhanHQ API access and preferred frontend/backend stack? 2. Should alerts support separate presets for different symbols, expiry dates, and market conditions?
