Profile

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
