Premiss and stock strategy testing
Premiss is an AI-assisted stock strategy tester for creating readable strategy code and running historical tests on supported stock and ETF markets. A useful stock backtest still needs explicit timing, data assumptions, costs, position sizing and a matched benchmark. Verify coverage before testing.
Begin with a clear request
Turn a stock trading idea into explicit rules in Premiss. Inspect the generated Python, the historical trades and the assumptions behind the result. The free tool on this website prepares a written specification or an educational calculation. Copy that result into Premiss and review the missing choices before running research.
Follow the evidence in the application
Premiss lets you describe custom trading rules, inspect generated Python and review historical simulated trades. Select a supported market and interval before a test. Keep research findings, historical backtests and forward paper observations as separate artifacts.
Understand the current offer
Premiss currently offers a free early-access plan with 15 backtests or research runs per month and up to 3 paper bots. Paid plans increase usage limits. Verify current allowances on the official pricing page. No plan includes a general direct exchange connection; live trading requires separate approval.
