Premiss

Turn your next trading idea into a strategy you can test and improve. Describe your rules in plain English, create custom Python strategies, and run historical backtests with Premiss from your conversation. Explore supported crypto, stock, and ETF markets. Build your own indicators, entry and exit rules, and risk controls using the same strategy engine as the Premiss app. See the trades behind the numbers, understand drawdowns, and compare completed results with a matched buy-and-hold baseline. Keep your code, strategies, and research notes together in your private Premiss workspace. Revisit an idea, change the rules, and run it again. A Premiss account is required. Available history and timeframes vary by market. Historical results do not predict future returns.
