Blave-TW/blave-agent ? reverse-engineered prompt

Build me a free macOS app that turns a trading idea into a real strategy with Claude Code or Codex.

I want to type something like “backtest BTCUSDT when the 20 day SMA crosses above the 60 day SMA, use a 0.05 percent fee, and show me the results,” then have the app write the strategy, run the backtest, and if I want, trade it live. It should support paper trading too, and make it easy to connect to exchanges like Binance, OKX, Bybit, Gate.io, or BingX without me having to paste secret keys into chat. Please include a clean desktop workspace, a way to see backtest results and live status, and safety features like a kill switch and clear logs of what it did.

If you need to, look up current docs online for the exchange or CLI setup. Keep it simple for a normal user, and make it work on macOS with a nice native feel.
