Premiss

Premiss is a platform that lets you describe a crypto trading strategy in plain English and have it generate the Python code, backtest it against historical market data, and run it forward in paper trading or live execution. You don't need to code. You write what you want the bot to do, the system translates that into a strategy, and you can inspect every line of logic before you let it touch real money. The AI generates readable, auditable Python, so you can see exactly what conditions trigger a buy or sell before committing any capital.

The problem it addresses is the gap between having a trading idea and testing it rigorously. Most people who want to automate a strategy either write code themselves, hire a developer, or use drag-and-drop builders that often obscure what's happening under the hood. Premiss takes the natural-language input and outputs readable Python, so you get automation without losing visibility. You can audit the code, see exactly what triggers a buy or sell, and modify it if you know enough Python to do so. The transparency is the point, you're not locked into a black box that hides the logic from you.

Under the hood, the platform backtests strategies against years of historical crypto data from the Binance spot market. It models fees for major exchanges including Binance, OKX, Bybit, Kraken Pro, and Coinbase Advanced, which matters because fee assumptions can make or break a strategy's profitability. Every backtest produces an auditable log with timestamps, entry and exit prices, and position sizing, so you can trace how the bot would have behaved in real market conditions. The results include returns, drawdown, Sharpe ratio, and win rates, giving you the numbers you need to decide whether the strategy is worth pursuing.

Once you're satisfied with the backtest, you can run paper trading on live market data. The bot executes simulated trades in real time without risking capital, which lets you see how it handles current volatility before you commit funds. Strategies run continuously as paper bots by default, so you can monitor performance over days or weeks before making any decisions about going live. For users who want to go further, Premiss offers early-access integration with Kraken for real-order execution, though the platform is clear that backtests and paper trades are hypothetical and don't guarantee future results.

The platform also supports signal integration. You can export entry and exit signals as JSON to custom URLs, which lets you plug Premiss into your own infrastructure or alerting system. This is useful if you want to run your own execution logic or simply receive notifications when the strategy triggers a trade. There's a Discord community for sharing strategies and getting support from other users and the founding team.

It fits crypto traders and investors who have ideas they want to test without manual coding or opaque visual builders. If you've ever wondered whether a simple moving average crossover actually works on your favorite pair, or whether a momentum signal beats buy-and-hold, Premiss lets you find out in an afternoon. The target audience skews toward people who want transparency, since the generated code is fully visible rather than locked in a black box. Strategy researchers and backtesting enthusiasts will find it useful for validating ideas before risking real money.

What sets it apart is the combination of natural-language input and code transparency. Plenty of bot builders generate strategies from templates, but fewer let you write in plain English and then hand you the underlying Python. The fee modeling across multiple exchanges is also useful if you trade on more than one platform and want realistic cost assumptions baked into your backtests.

Pricing is free to start. You get daily credits for chatting, backtesting, and running paper bots without entering a credit card. The site doesn't detail paid tiers on the homepage, so you'll need to check inside the app for credit limits and upgrade options. Live trading through Kraken is gated behind early access with limited participants, so full automation isn't available to everyone yet. The company behind Premiss is LoraLabs, reachable at founders@loralabs.co. Premiss won't replace professional quant infrastructure, and it's careful to disclaim that past performance doesn't predict future results. But for casual to intermediate traders who want to stop guessing and start testing, it's a low-friction way to turn an idea into data.
