MarginMinder

MarginMinder is a web + mobile app that stress-tests your options portfolio against broker-style margin rules and realistic shock scenarios (gap moves, vol crush/expansion, correlation breaks). Users connect their brokerage via read-only integrations, and the app continuously estimates buying power, worst-case margin, liquidation risk, and “what breaks first” positions. It’s not a trading app; it’s a risk early-warning system with clear, actionable alerts (e.g., “If SPY drops 3% and IV +20%, you’ll breach margin by $4,200”). It also explains which spreads/legs drive the risk and suggests conservative adjustments (reduce size, roll, convert to defined-risk) without pretending to be a magic profit machine. The UI focuses on a single truth: can you survive the next ugly move? Brutal honesty: data quality and broker rule differences are hard, so the MVP should support a small set of brokers and strategies first.
