And now, backtesting is just as easy. The IVolAI Module lets you describe any options strategy in plain English — our AI generates ready-to-run code with real bid/ask pricing, intraday stop-loss, and optimization. From idea to equity curve, no coding needed.

Frequently Asked Questions

View full FAQ →

Log in to your account, open VS Code, and in the upper menu select the Claude Code tab. Then just tell it what you want to test ("backtest a straddle on SPY"). That triggers /generate_backtest, and the agent walks you through a 5-layer interview before writing any code. No code is generated until all 5 layers are confirmed — this prevents silent default assumptions.

No separate subscription required. When you start your trial we provide $50 of AI credit for free so you can begin immediately, and you can top up the AI key later as needed. Alternatively, you can bring your own AI subscription/key if you prefer.

Yes. Without AI, you can use our API as a regular API — pull data and run things yourself. The AI layer is what lets you talk directly to the backtesting module, which knows how to run backtests and writes them for you. With AI, all you do is run the backtests or improve them through chat; without it, you build everything manually against the API.

We offer a 7-day free trial for all retail tariffs, allowing you to subscribe and request data via API without limits. For professional use, please contact sales@ivolatility.com.

VS Code (Visual Studio Code) is a free, widely-used code editor from Microsoft — it's the environment where the IVolAI chat and tools live. The basic configuration is included in your subscription at no extra charge — there's nothing additional to buy. Alternatively, you can use your own workspace and install the backtesting module there.

IVolAI is our Backtesting module — a set of pre-defined backtesting tasks that you don't need to code yourself. You talk to it through an AI like Claude: just describe what you want in plain English, and the AI calls the module to generate and run backtests on IVolatility historical data. The module already knows how to do (1) backtest generation (straddles, strangles, single calls/puts, spreads, earnings optimization) and (2) data navigation — what instruments, symbols, and listed options exist across regions.

Yes. IVolAI is an extension of the IVolatility API — to run backtests, it needs access to data through the API. You'll need an active API subscription and an API key for IVolAI to fetch and analyze the data.

You can top up directly from your account: go to API & AI Keys and use the Add Credits to your AI Key option.

Limits for professional use are subject to agreement. For retail plans, both history depth and monthly request volume depend on the tier:

Plan History Monthly limit Request rate
Builder 3 years 20,000 requests 1 / sec (burst 5)
Quant 5 years 100,000 requests 1 / sec (burst 5)
Lab 20+ years Unlimited 1 / sec (burst 5)

Note: Please note that retail subscriptions are not designed for downloading all market data. Attempts to do so may lead to account suspension. For large data requests, we suggest contacting support@ivolatility.com.

The questions the agent asks before generating:

Layer 1 — Entry signal: when to open a position (IV Z-Score, term structure, earnings, etc.)
Layer 2 — Implementation: which contract to trade (strike, expiration, type)
Layer 3 — Optimization combos: what to sweep in a parameter grid
Layer 4 — Risk management: when to exit (stop-loss, take-profit, EOD)
Layer 5 — Universe: which symbols

Backtesting, in your AI

Install the IVolAI agent into the AI tool you already use and describe any options strategy in plain English — it writes the code, runs it and returns a full backtest: real bid/ask pricing, intraday stop-loss, optimization and an equity curve.
