Bull or Bust: Trading Sim

Practice trading risk-free in a live candlestick sandbox, then paper-trade real market data through your own free Alpaca account — real prices, zero real money.

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.

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.
