VibeTradingLabs/vibetrading ? reverse-engineered prompt

Build me a Python trading framework for crypto that lets a user describe a strategy in plain English, turns that into working strategy code, checks it for common mistakes, backtests it on historical market data, and then gives a simple performance summary with helpful suggestions.

I want built in strategy templates too, like momentum, mean reversion, grid trading, and dollar cost averaging, so people can use it without an AI key if they want. It should also support live trading on a few exchanges, with the same strategy code working in both backtests and live mode.

Please include a command line tool for generating, validating, downloading data, and running backtests from the terminal. Make it feel polished and practical, with realistic fees, slippage, leverage, and risk management. If you need anything current from the docs or exchange APIs, look it up online first.
