Hey HN! I built Paper, a paper trading platform that actually simulates the messy reality of trading - slippage, partial fills, market impact, and real execution logic. The Problem: Most paper trading platforms give you fantasy fills at perfect prices. You develop a strategy that works great in simulation, then lose money when you go live because it never accounted for real market dynamics. What Makes Paper Different: - Simulates 22 real brokers with their exact rules, restrictions, and fee structures - Real market dynamics: slippage, partial fills, market impact - Configurable latency profiles: Retail (50-250ms), Institutional (20-100ms), Colocated (0.5-5ms), or Custom - L1 NBBO price feeds with realistic fill prices - Extended hours trading (4am-8pm ET) - Full margin trading (Reg T and Portfolio Margin with SIMPLE/SPAN/TIMS) - Short selling with proper locate requirements - Real PDT rule enforcement First Trading Platform with MCP (Model Context Protocol): We're the first to ship MCP support! Test your trading strategies with Claude directly: - npm install @paperinvest/mcp-server - Build and backtest strategies using AI - Claude can place trades, check positions, analyze performance - Full API access through MCP tools Tech Stack: - NestJS backend with PostgreSQL, Redis, Kafka - Next.js 15 frontend - SSE for real-time order streaming - REST API + MCP server - AWS deployment Pricing: - Free: 5 trades/day, basic orders, cash account - Pro ($20/mo): Unlimited trades, all order types, margin accounts, extended hours - Commercial ($500+/mo): Multi-account support for businesses Coming Soon: Options trading (full multi-leg strategies) and futures I'm a solo developer. Built this because I was tired of strategies that worked perfectly in ThinkorSwim's paper trading but failed with real money due to unrealistic fills. Try it: https://paperinvest.io API Docs: https://docs.paperinvest.io Would love feedback! What broker rules or market dynamics do you wish paper trading platforms simulated better?

About a year ago, I built an ETL system to extract and process product data from e-commerce websites, mainly supplements. It maps product structures, automates data collection, cleans and classifies the information, and uploads it directly to Shopify through API integration.

The system uses Python and Selenium for extraction, with transformation steps focused on cleaning, enrichment, and product classification. It was designed to be modular and easy to extend to new websites.

I paused development but I'm considering reviving it. Feedback or suggestions are welcome.
