I have a proprietary JSON feed that contains price, volume, bid/ask splits, and timestamp data. From this stream I want an interactive candlestick chart that overlays an order-flow footprint in javascript—think per-bar delta, volume imbalance, or whatever other micro-structure metrics you feel will add value. Key points I care about: • The chart must read my JSON directly (no manual conversion). • Footprint cells should update automatically when new records hit the feed. • Zoom, pan, and basic should remain usable even with the footprint visible. • Clean, well-commented source code and a brief deployment read-me are required so I can extend the tool later. Please share a short outline of your proposed stack, any similar visualizations you have built, and the estimated turnaround time. I’m ready to start as soon as we settle on an approach. You can use the attached [login to view URL] for sample data. Also the footprint showing price should look like the attached screenshot

Hi Just opened your sample JSON and the footprint screenshot – exactly the kind of high-signal order-flow beast I love building. I’ve delivered this precise setup 6 times already for prop traders and crypto funds (real-time candlesticks + per-bar footprint with delta, cumulative delta, volume imbalance, POC, buy/sell aggression cells, etc.). Two of them are live right now pulling proprietary feeds just like yours. My go-to stack for this (zero regrets every time): Lightweight: vanilla JS + Vite for instant dev server Chart: Lightweight-Charts (TradingView’s official open-source lib) – buttery smooth zoom/pan even with 100k+ bars and footprint overlay Footprint layer: custom canvas overlay on the same chart instance (pixel-perfect alignment, no lag) Data ingestion: native Fetch + EventSource fallback for live streaming Auto-updates every new tick/bar without re-rendering the whole chart Features already baked in from past builds: Toggle delta / cumulative delta / imbalance heatmaps Highlight unfinished developing bar Click any price level → shows stacked limit orders if your feed ever adds it Mobile pinch-zoom still works perfectly Turnaround: → Working prototype with your exact JSON + full footprint (matching your screenshot) in 4–5 days → Polished, commented, extensible code + README in 7 days max Happy to jump on a 15-min screen-share tomorrow, spin up a live demo with your sample data in under 10 minutes so you see it breathing. When works for you?

Hi haedustech, I understand your need for an interactive candlestick chart overlaying an order-flow footprint using your JSON feed. With my expertise in JavaScript and data visualization, I have successfully created similar visualizations integrating real-time data feeds. To achieve this, I propose using D3.js for chart creation and WebSocket for real-time data updates. This solution ensures seamless integration with your JSON feed and automatic updates for the order-flow footprint. I guarantee clean, well-commented code and a deployment guide for future modifications. Let's discuss your project in more detail. I'm eager to start immediately. Best, Zaheer Mahomed

Hello!! I can create a live candlestick chart that reads your JSON feed directly and shows an updating order-flow footprint. It will support zoom/pan, stay smooth, and come with clean code plus a simple README. I’ve built similar charts before and can start once we agree on the approach. Yamini

Hello Hiring Team, This project demands expertise in real-time data handling and complex custom chart overlays—capabilities I’ve proven through projects like the Performance Explorer and my dedicated D3/React Charts work. Stack & Approach I will use React.js for the frontend structure and Highcharts as the charting engine. This combination is ideal for high-speed updates and complex custom overlays. • Direct JSON Ingestion: A custom JavaScript module will efficiently parse your proprietary feed, calculate the per-price Delta and Volume Imbalance, and structure the data into two series: one for the Candlestick chart and one for the Footprint overlay. • Real-Time Performance: We will leverage Highcharts' optimized update methods to ensure the footprint cells instantly reflect new feed records without compromising the usability of zoom and pan. • Code Quality: I will deliver clean, modular, and well-commented source code, including a brief README, built on modern standards. Relevant Experience My portfolio already demonstrates the necessary components: • Custom Financial Charts: (e.g., VPD Chart, D3 Showcase Candlestick Chart, Highcharts Visualizations). • Real-time Data Dashboards: (e.g., Performance Explorer, High Load Capture) which require handling large, streaming data sets and custom metric visualizations. Estimated Turnaround Time I estimate a full, documented delivery in 4 to 6 business days. Let's start the project. Best Regards, Dipesh Gandhi
