The built-in AI agent writes the strategy from a plain-English description. The engine backtests it across 6 US index and ETF underlyings, with slippage and commissions modeled, then trades it live through your Interactive Brokers account.
No account, no card · SPX options up to seven days from expiry
Xavi's drawing of a real strategy, and that strategy's backtest on historical SPX data. Simulated results, not a track record.
The problem
On paper the strategy is mechanical: these strikes, this credit, that stop. Live, it runs through you, so you hesitate on the entry, snatch the winner early out of fear, widen the stop to avoid being wrong, sit out the next trade after a red day. Every flinch is a fresh place for real results to drift from the plan you actually tested.
StratVerra trades the rules exactly as written: the same entries, the same stops, and the same code path that ran the backtest. It does not get scared, second-guess the rules or have a bad day, so the strategy you validated is the strategy that fills.
How it works
Build
Tell the AI agent what you want in plain English, or compose it from blocks. Neither way needs code.
Ask Xavi, the AI agent built into the app. It writes and backtests real custom strategies on your account. Or connect the assistant you already use, like Claude or ChatGPT, and it does the same work. Neither one can ever place a live order.
Rather build it yourself? Compose When / If / Enter / Exit blocks into an entry-and-exit rule, or open what the agent wrote and change it, without writing code.
Strategies are versioned. The same inputs give the same result, every run.
Backtest
Run it on real minute data, with slippage and commissions included.
SPX, XSP, RUT, SPY, QQQ, IWM: full option chains at minute resolution, hosted and included. Your backtests and your agent both run on this data.
Bid/ask or mid slippage and per-contract commission, applied at run time and kept out of the strategy itself.
Same settlement path for same-day and DTE ≥ 0 positions. 0DTE is just the DTE = 0 case.
Go live
Trade the same strategy through your own broker. Paper first, then live.
The engine that backtests your strategy is the engine that trades it live, so test and live cannot drift apart.
Orders route to Interactive Brokers, MEXEM, LYNX or Easybroker over the native TWS API. They are placed by the engine, not queued for you to send. Paper first, then live.
Backtests run on hosted option data, so you have no data to prepare and nothing to run locally. Live orders are placed by the app on your machine, straight to your own broker gateway.
Build and backtest in your browser. Install the desktop app only when you're ready to connect a broker for paper or live execution.
Fills are where a backtest is usually wrong. Read exactly how ours are modelled, including what the simulation deliberately does not model.

Strategy examples
Two things people asked the agent for, and what it came back with. Both land in your library beside the strategies you built by hand. Every strike, time and stop it chose is a setting you can read and change yourself.
You asked
“Sell an iron condor on SPX every morning, but skip the days the market is trending hard.”
Your agent built
You asked
“If SPX breaks out of its opening range with conviction, buy the move with defined risk.”

Run detail
Open a finished run and you get the settings it ran with, the numbers, the charts, and then every fill and every round-trip trade in tables you can scroll.
The page opens on the headline metrics, over the equity curve they came from:
The strike map draws every leg at its strike, for exactly as long as it was open, over the underlying's price that session. Solid lines are the shorts you carry the risk on; dashed are the long wings.
Step through the run a day at a time and you can see whether price ever came near a short, or whether the trade only looked safe in the P/L column.
Illustrative, not a track record

FAQ

StratVerra is an options backtesting app with a built-in AI agent, Xavi. You describe a strategy in plain English, Xavi writes it, and the engine backtests it on minute-level option chains for SPX, XSP, RUT, SPY, QQQ and IWM, with slippage, commissions and Reg-T margin modeled. The same engine can then trade it live through your own Interactive Brokers account.
Yes. It is how most people build one. There is an AI agent built into the app called Xavi, and you can connect the assistant you already use (Claude, ChatGPT and others) to your account instead. Either one writes a custom strategy, backtests it, reads the results back and fixes what didn't work. Xavi signs in as you, the strategies land in your library, and neither is ever able to place a live order.
No, and you don't have to build the strategy yourself either. Describe what you want and the built-in AI agent (or your own) writes a custom strategy for you. If you'd rather do it by hand, strategies are also built from composable blocks in the app, and anything the agent writes can be opened and changed there.
Only for live trading. Backtests run on the hosted option data included with your subscription, so you can build and test a strategy before you ever connect a broker.
Build and backtest in your browser. Install the desktop app only when you're ready to connect a broker for paper or live execution. The free trial needs nothing installed: you sign in, build a strategy and run backtests in the browser. The desktop app is free, and it is the step you take when you want the engine placing real orders through your own broker gateway.
Interactive Brokers, MEXEM, LYNX and Easybroker. The last three are Introducing Brokers to Interactive Brokers: your account is with them, the trades clear at IBKR, and the software they give you is IBKR's Trader Workstation or Gateway under their branding. So all four connect the same way, over the same API.
Minute-level option chains on SPX, XSP, RUT, SPY, QQQ and IWM, hosted and included with your subscription. There is nothing to buy separately and nothing to download. The app shows you exactly which dates are available for each one when you set up a backtest.
Fourteen days, and it takes no card at all. Sign in at the browser app and start the trial from there. There is no payment page and nothing to enter. If you do nothing it simply ends: with no card on file there is nothing to charge and nothing to remember to cancel. To carry on, add a payment method before day 14. There is one free trial per account, so if you have subscribed before, a new subscription starts billing straight away. The listed price includes VAT: $49 a month is the amount actually charged, wherever you are.
Your plan includes a fair-use AI allowance that resets at the start of every month. If you use it up, you can add another month's worth for $9 at any time, from inside the app. It is added straight away and it never expires, so anything you don't use carries over.
Backtests run in the cloud on hosted data. Live trading runs on your machine: the app starts the engine locally and connects to your own broker gateway, so your orders go straight from you to your broker.
US index and ETF options: SPX, XSP, RUT settle in cash at expiry, and SPY, QQQ, IWM are American-style, so a short leg can be assigned early. All 6 run across 0DTE and multi-day expirations. The engine itself is built broker- and market-agnostic.
No. StratVerra is software for building and running your own strategies. It is not investment advice and does not manage money.
