Premiss is a tool that turns a trading idea written in plain English into a real Python backtest on years of real market data, returning the generated code, the trades it placed, and a verified result in seconds.

Do I need to know how to code to use Premiss?

No. You describe a trading idea the way you would say it out loud - for example, 'Hold bitcoin while it's above its 100-day average.' Premiss writes the Python backtest for you.

What data does Premiss backtest against?

Premiss runs backtests on years of real market data, such as real Binance candles, so every trade and result is auditable.
