Meet Xavi. Describe an options strategy, and Xavi writes it and backtests it on real option chains.
Xavi answers like a quant: ask how a strategy did and it tells you plainly, including when the answer is a poor one.
Try it yourself
First it shows you its plan. Say go, and it writes the strategy, runs the backtest and reads the numbers back. It will not tell you what to trade. The preview tests SPX over the last six months and runs three backtests; an account tests SPX, XSP, RUT, SPY, QQQ and IWM over the full history.
What to put in the sentence
Naming a strategy is enough to start: Xavi lays out what it understood before it builds anything. A sentence that already says these five things saves the round trip.
The underlying, and the expiry
a weekly SPX put credit spread
When it opens
enter at 11:00 ET, only when RSI(14) is between 47 and 53
The structure, and where the strikes go
sell the 16-delta put and buy the put 25 points below it
What gets it in, and what gets it out
require at least 0.75 dollars of credit, take profit at half the credit, stop at 2x, close at 15:45 ET
The window, and the question
backtest it from 2021-01-04 to 2023-12-29 and tell me how it did
What Xavi does, and what it cannot do
Every step shows as a row in the transcript, so you see what Xavi did rather than take its word for it: it reads how a strategy is written, checks which dates the data covers, writes the strategy, runs the backtest, reads the result back, and fixes what did not run.
- It cannot place a live order.Its toolset is writing and testing; nothing in it reaches a broker, your subscription, or anything outside your own account.
- It cannot go live on its own.Nothing runs live until you approve it yourself. Every version needs its own approval; backtests need none.
- It can be wrong.Read what it wrote before you trade it. The app says so on every assistant screen.
Ask Xavi for one
Xavi comes with the app, and so does the data every backtest runs on. What it writes lands in your library as a real strategy, every version kept, that you can open, read, change by hand and run again.
