Backstory: I wanted to play with intraday stock data but couldn't find a free dataset anywhere. IEXCloud [1] offers API access to 1-minute granularity intraday historical price data, but I was worried that it could get expensive or unwieldy to build up a substantial dataset via API calls. Plus, IEX gives out their raw data for free. I probably should have just used the IEXTools python library [2] to parse IEX's raw data dumps, but I was working on a Julia project, so it felt more thematically appropriate to build a new tool from scratch. I haven't been actively using InvestorsExchange.jl a…

I built TradeSight (https://tradesight.live) as a lightweight market risk indicator that combines real-time data with AI insights. The backend is written in Rust, with a vanilla JS frontend for maximum performance. It aggregates data from multiple sources (FRED API, Yahoo Finance) and uses Claude's API to provide detailed market analysis. Technical stack: - No login required - static page with hourly updates - Rust backend for efficient data aggregation - Vanilla JavaScript frontend for minimal overhead - Claude API integration for real-time market analysis - Data sources: FRED…

StoxGPT▲12Hi HN, I built *StoxGPT*, a TradingView-powered chart where you control everything by chat. Example: > *You*: add RSI > *Chart*: (RSI indicator appears) > *You*: change ticker to AMZN > *Chart*: (switches symbols) No menus, no hotkeys—just natural language mapped to the TradingView JS API. --- ### Why? I got tired of drilling through panels to add indicators or tweak settings. A chatbot front-end felt faster, so I wired GPT-3.5-Turbo to TradingView’s `widget.activeChart()` calls. --- ### How it works * *React + Next.js* front-end * *Dummy OHLCV generator* (open-source) for this demo * Simple…
