Eight steps, no code
QuantDesk Backtest plugs into your assistant through a connector (an MCP server, the standard way assistants reach outside tools). Your assistant fetches historical 1-minute option data, runs the backtest inside QuantDesk and brings the results back to your chat.

In Claude: Settings → Connectors. In ChatGPT: a paid plan with Developer Mode, then a new custom connector. Menu names change from time to time; search the assistant's help for "custom connectors" if you cannot find them.
Click + Add custom connector.

Your assistant opens the QuantDesk sign-in page. Use the same Google account you use, or will use, for LiveDesk. New here? Continuing with Google creates your account, and your first 24 hours include full Pro access.
Click Connect on the new connector, then Continue with Google.

4Ask in plain English
Be specific: instrument, entry and exit times, how strikes are picked, the stop-loss, and the dates. If the assistant asks permission to use a QuantDesk tool, allow it. Success is a summary with the backtest's metrics.
Start a new chat and type: "Backtest a NIFTY short straddle over the last 6 months."
Prompts that work (copy and change the numbers)
Backtest a NIFTY short straddle: sell the ATM call and put at 09:20, stop-loss 25% on the combined premium, exit at 15:15. Use the last 6 months and show me the key metrics.Run the same straddle on SENSEX for the same dates, then compare the two backtests side by side.Run a quick optimisation of the stop-loss at 20%, 25%, 30% and 40%, and explain the trade-off.Backtest an SPX 0DTE short strangle using the Python engine: sell 10-point OTM at 10:00 ET, exit at 15:45 ET. -
5Dig in with follow-ups
Metrics, the trade list and mark-to-market P&L come back into the chat. Ask to compare two runs, optimise a setting, show the worst days, or explain a bad day. An optimisation or a Monte-Carlo run counts as a backtest.
Ask: "Show me the exact parameters you used." Correct anything that is off, then run it again.

6Know the Free limits
Free is enough to learn the workflow on NIFTY and SENSEX. Pro removes the limits and adds MCX commodities, US SPX and SPY (Python engine, 0DTE by default, 1–5 days to expiry) and a saved library of AI-written Python backtests.
A limit message means: wait for next month, adjust the request, or buy a pass.
What you can backtest
- India index options on real 1-minute option-chain data; option-chain lookups (the chain at any minute, a strike by premium, the ATM straddle at a time).
- Option buying and signals: buy-side templates, indicator history, signal tests.
- MCX commodities (Pro): continuous futures and monthly options.
- US SPX and SPY (Pro): saved after each US close, recent and growing.
- NSE stocks and mutual funds: a scanner with 40+ presets, fundamentals, stage analysis, fund comparison.
- Crypto: Binance spot pairs and Delta Exchange BTC and ETH options.

7Buy a Pro pass when you need more
Pro is sold as passes: pay once for a number of days, no auto-renew. Another pass adds its days on top of what you have left. Passes take no coupon. If you also trade on LiveDesk, a Backtest + LiveDesk combo credits both in one payment.
Buy on the Backtest sign-in page; see Plans and pricing for the combo.

8Take it to LiveDesk, on paper first
When a backtest looks promising, build the same structure from a template in LiveDesk, deploy it on Paper, watch it for a few sessions, and compare the paper results in Reports with your backtest before going live. A backtest is not a promise: live fills, costs and future markets differ.
Open LiveDesk → Create Strategy → a matching template → Deploy · Paper.
What can go wrong
- The assistant answers without using QuantDesk
Start a new chat, make sure the connector is connected (Claude) or switched on (ChatGPT), and say "use QuantDesk". Allow the tool if asked.
- It asks you to sign in again
Open the connector in your assistant's settings, click Connect, sign in with the same Google account.
- A limit message on the Free plan
This month's backtests or AI actions are used, the data is older than 6 months, or the instrument is outside NIFTY and SENSEX. Wait, adjust, or buy a pass.
- SPX, SPY or MCX requests are refused
US and MCX tools are Pro only. A pass unlocks them immediately.
- A rate-limit message
Too many tool calls in a short time. Wait a minute and ask again.
- ChatGPT or Gemini has no connector option
ChatGPT needs a paid plan with Developer Mode. For Gemini, use Gemini CLI; the Gemini app does not support custom connectors.
Frequently asked questions
Do I need to know how to code?
No. You describe the strategy in plain English and your AI assistant calls QuantDesk's tools. If a rule is too unusual for the built-in templates, the assistant can write a Python backtest that runs on QuantDesk, and that works on the Free plan too.
Is QuantDesk Backtest free?
There is a Free plan: 5 backtests and 500 AI actions a month, the last 6 months of data, and NIFTY and SENSEX for F&O. Your first 24 hours after signing up have full Pro access. Pro passes unlock everything else.
Which AI assistants work with QuantDesk?
Claude on web, desktop and mobile; ChatGPT on a paid plan with Developer Mode and custom connectors; Gemini CLI (the consumer Gemini app has no custom-connector option); Grok; Perplexity Pro and above; and Cursor, Windsurf and VS Code.
Do Pro passes renew automatically?
No. Each pass is a one-time payment for a number of days. Buying another pass adds its days on top of the time you have left.
Does a good backtest mean the strategy will make money?
No. A backtest shows how rules would have behaved on past data. Real fills, costs and future markets differ. Paper trade a strategy on LiveDesk before you risk money.
