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?
