## About

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.

## How to use

1. **Add it in ChatGPT** Open Premiss in ChatGPT's Plugin directory (button above), select + to add it and sign in if asked.

2. **Use it in a chat** Type @ in the composer and pick Premiss, or start your message with its name. ChatGPT may also suggest it when it fits what you ask.

## Skills

- **premiss-research**: Create and edit Python strategies, discover supported markets, run historical backtests, inspect saved code and results, and keep private research notes in a connected Premiss workspace. Use when the user requests these tasks with Premiss.
