Xavi, 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. The preview tests SPX options up to seven days from expiry, over the last six months, and runs three backtests.

Its backtest on SPX, 2022-09-14 to 2026-09-14
Xavi's drawing of a real strategy, and that strategy's backtest on historical SPX data. Simulated results, not a track record.
An example day, ET. Not a record of a trade.
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 new place for real results to drift from the plan you actually tested.
The same entries and the same stops, run by the same engine that ran the backtest. It does not get scared or have a bad day, so the strategy you validated is the strategy that fills.
Build
Tell the AI agent what you want in plain English, or compose it from blocks. Neither way needs code.
Backtest
Run it on real minute data, with slippage and commissions included.
Go live
Trade the same strategy through your own broker, paper first, then live. The app on your machine places the orders, so it stays open while a strategy trades.
Build
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
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-day and longer-dated positions settle by the same rules, so a 0DTE strategy and a weekly one are tested the same way.
Go 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 through your own broker gateway. The strategy decides each order, and on a real-money account you approve it in the app before it goes out. 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.
Already use ChatGPT, Claude or another assistant that supports MCP? Connect it to your StratVerra account and it can write and backtest strategies there. Backtests use your credits or subscription, and it cannot place a live order.

Two things people asked the agent for, and what it came back with. Every strike, time and stop it chose is a setting you can read and change yourself.

How to backtest a 0DTE options strategy without writing code
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. These are the backtest from the top of this page, SPX from 2022-09-14 to 2026-09-14:
That is 5.8% a year. The fills used the Slippage model, so $13,408 of slippage and $1,599 of commissions are already taken out.
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. This is its last day, the one the page opens on: a 7,575/7,525 put spread opened at 10:31 ET and held to expiry, its short strike 18 points under the day's low.
This run is the SPX 0DTE morning-trend credit spread. Its own page has the prompt that builds it and its year-by-year results.
Simulated results, not a track record.

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.
Not to try it. Backtests run on hosted option data, 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. Trying it 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.
Yes. Live trading runs in the desktop app on your computer, not in the cloud, so the app has to stay open and the computer awake while a strategy trades. If you close the app during a run, it asks whether to keep your open positions or close them. Either way it cancels the run's working orders, including any stop-loss resting at your broker, so a position you keep is no longer watched. If the connection to your broker drops, the run stops and closes nothing: your positions stay open for you to check at your broker, and it does not restart by itself. On a real-money account every order also waits for you to approve it in the app, so a run needs you there to trade at all. You log in to your broker in its own Trader Workstation or Gateway: StratVerra never sees that password, and saves only the connection details to your account.
There is no free trial of the subscription; it is charged from the day you subscribe. Instead every account gets 100 free credits, once, with no card: enough for 10 backtests, or a mix with Xavi.
Every account gets 100 free credits, once. Claim them in the app after you sign in. It takes no card and starts no subscription. They pay for 10 backtests, or a mix of backtests and AI, and they never expire. A backtest that fails gives its credits back. When they run out, your strategies stay and you can keep editing them. Backtests and Xavi wait until you buy a pack or subscribe. Paper and live trading need the subscription, which is charged from the day you subscribe. Tax included: VAT or local sales tax. Nothing is added at checkout.
On credits, each AI message is paid from your balance, about 2 credits for a typical one. When your credits run out, Xavi waits until you buy a pack or subscribe. On the subscription, the plan includes 100 credits of AI a month, and the allowance resets at the start of every month. If you use it up, you can buy 100 credits for $9 at any time, from inside the app. They are added straight away and never expire, so anything you don't use carries over.
Yes. Every account starts with 100 free credits, and when they run out you can buy more in the app instead of subscribing: $9 for 100 credits, tax included. A backtest uses 10 credits and a typical AI message about 2. Credits never expire. Paper and live trading need the subscription.
It depends on how many backtests you run. On packs, a backtest costs $0.90. At that rate, $49, the price of a month of the subscription, pays for about 54 backtests. The subscription has no limit on backtests, so if you run more than that each month, it costs less. It also adds paper and live trading and an AI allowance of 100 credits a month.
Yes. Cancel any time under Manage billing in the app. You keep full access until the end of the period you paid for.
No. StratVerra is software for building and running your own strategies. It is not investment advice and does not manage money.
Build strategies, backtest them and ask Xavi. No card and nothing to install.
