If you can describe it,
you can trade it.

Weather, election odds, on-chain flows, news volume, anything with a number. Describe a data source in plain English and SignalAI writes the code, deploys it live, and streams it on your schedule. Then build a strategy on top and backtest it on real market history, honestly: real fills, real costs, no lookahead.

Signals that don’t come in a menu.

These aren’t preset indicators. Someone described each one in a sentence, and an agent researched the source, wrote the code, and deployed it live.

How it works

From a sentence to a live signal, then an honest backtest.

01
Describe
Say what you want to track, in plain English. No code, no formulas.
02
The agent builds it
It researches the source, writes and sandboxes the code, and deploys a live signal on your schedule.
03
Compose a strategy
Combine your signals into buy and sell rules, also in plain English.
04
Backtest honestly
Replay on real market history. Real fills, real fees, no lookahead, no pretty fake curves.
Honest by default

The number after the costs everyone else hides.

Most backtesters flatter you: no fees, no slippage, and a peek at tomorrow’s price. Ours doesn’t. Every run is priced like a real account and blind to the future.
