Bull or Bust: Trading Sim

Bull or Bust is a two-mode trading teacher — practice the mechanics risk-free, then step up to real market data. Both modes are built to teach, and neither one touches real money. LEARN — a risk-free sandbox (free) Trade a live candlestick chart with virtual cash on a market that's generated fresh on your device — so no two runs are the same. Step the market forward candle by candle, or hit Auto and watch it run. Track your equity curve, realized P&L, win rate, and the stat the pros obsess over: your maximum drawdown. Test yourself across five scenarios — Bull Run, Bear Market, Choppy, High Volatility, and Rally-then-Crash — with a per-trade fee baked in so you feel how costs quietly eat returns. Seven built-in lessons distill hard-won ideas: why spreads and fees matter, why position sizing beats being right, the brutal math of drawdowns, and why chasing green candles is a trap. Works fully offline, no account, nothing collected. LIVE — paper trading with real market data (one-time Pro unlock) When you're ready for the real thing without the risk, connect your own free Alpaca paper-trading account and trade a simulated cash balance against real, live market data. Paper trading means fake money and real prices — no real funds are ever involved, and Bull or Bust connects to paper trading only, never live. See real-time IEX quotes, live candlestick charts, and place market and limit orders, then track your real positions, orders, and profit & loss. Your Alpaca API keys are stored only on your device (in the iOS Keychain), are sent only to Alpaca's paper servers, and are never uploaded to us or logged. FEATURES • Learn mode: live candlestick chart with a moving-average overlay and your entry line • Buy, sell, and close with virtual cash; step or auto-play the market • Equity curve, return, realized P&L, max drawdown, win rate, and full trade history • Five distinct, randomly generated market scenarios • Seven built-in lessons • Live mode (Pro): real-time IEX quotes, live charts, market & limit paper orders, positions & P&L via your own Alpaca paper account • Haptic feedback on trades · Learn mode works fully offline · No account for Learn mode · No ads Bull or Bust is an educational simulator. Learn mode's markets are randomly generated — there are no real prices there. Live mode shows real market data but trades only in a paper (simulated) account using your own Alpaca paper keys — no real money, no real brokerage account with us, and no order is ever sent to a live exchange. Nothing in the app is financial advice.
