OptionStrategyBuilder.in is a calculator. It computes payoff, max profit/loss, Greeks, and breakeven figures for 44 predefined option strategies and for custom strategies you build yourself — across Nifty, Bank Nifty, and 208 individual F&O stocks — and displays them.
It does not recommend any strategy, does not rank strategies as "best," and does not provide personalized investment advice. Every figure shown is computed the same way for every user — nothing is tailored to your holdings, risk profile, or account history.
Beyond the scanner and builder, the site includes an options screener (filter every strike by IV, open interest, and volume), a global market events calendar (RBI, US Fed, ECB, BoJ, BoE decisions and more, purely informational), and price alerts that email you once when an index or stock crosses a level you set.
Some indexes on this site currently show illustrative sample data while live market data integration is completed for that index — this is stated clearly wherever it applies. We do not present sample data as live without saying so.
Free plan: full access to the strategy scanner (all 44 strategies), the options screener, the events calendar, an unlimited-leg custom builder, up to 2 saved strategies, and up to 5 active price alerts.
Pro plan: ₹299 for 30 days of unlimited saved strategies, up to 20 active price alerts, and an ad-free experience — charged once via Razorpay, access does not auto-renew.
Users make their own decisions about which strategies, if any, to consider. This is a tool for calculation, not a source of recommendations.
Does this recommend which strategy to use?
No. The scanner and builder display computed figures for every strategy the same way — nothing is ranked, highlighted, or suggested as "best." You decide what, if anything, to consider.
Where does the option chain data come from?
Nifty 50, Bank Nifty, Midcap Select, and Sensex use a live NSE/BSE option chain via Upstox, refreshed continuously during market hours. Other indexes currently show illustrative Nifty sample data with a clear notice, until their own live feed is wired in.
Is the custom builder free?
Yes — building is completely free and unlimited for everyone, any number of legs. The only limit is how many strategies a free account can save (2 strategies by default); Pro removes that save limit.
How often is data updated?
Every 60 seconds during market hours for live-wired indexes. A page also auto-refreshes itself every 60 seconds where relevant, so you don't need to manually reload.
What do the "Live" and "Est." labels next to a premium mean?
"Live" means that number is a real quoted market premium. "Est." means no real quote was available for that exact strike/date, so it's a Black-Scholes theoretical estimate instead. We show this distinction openly rather than presenting an estimate as if it were real.
What is "Current P/L" on the scanner?
It compares a strategy's value right now to its value at today's market open (9:15 AM) — real day-over-day movement, not a prediction. It shows "N/A" until an opening snapshot has been captured for that day.
Does my Pro subscription auto-renew?
No. Pro is a one-time payment for a fixed number of days (30 by default). There's no recurring charge — you pay again only if you want to continue after it lapses.
Can I sign up with Google instead of a password?
Yes, both email/password and Google Sign-In are supported. You can also link Google to an existing email account.
If I edit and re-save a strategy, does it overwrite the original?
No — saving always creates a new entry. Your original stays untouched, so you can compare versions on the Saved strategies page rather than losing an earlier one.
Is this investment advice?
No. This is a calculator that computes figures from market data using standard formulas. Nothing here is a recommendation, and we are not registered investment advisers. See our Terms for the full disclaimer.
Is my payment information stored on your servers?
No. Card, UPI, and bank details are handled entirely by Razorpay, which is PCI-DSS compliant. We only store a payment reference, never your actual payment details.
How do I request a refund?
See the Refund policy tab above, or email support@optionstrategybuilder.in with your registered email and payment reference.
What we collect: your email address; a hashed password (if you register with email) or your Google account identifier (if you sign in with Google — we never see your Google password); a Razorpay payment reference for Pro purchases; and the strategies you choose to save to your account. We do not collect or store your card, UPI, or bank details — Razorpay handles that directly and is PCI-DSS compliant.
Why we collect it: to create and secure your account, provide the saved-strategy feature, process Pro plan payments, and prevent abuse.
Who we share it with: Razorpay (payment processing) and Google (sign-in), each governed by their own privacy policies. We do not sell personal data or share it with advertisers. Market data (option chain and price feeds) shown on the site is not personal data.
Your rights: you can request access to, correction of, or deletion of your personal data at any time by emailing support. Account data is retained while your account is active and deleted within 30 days of a verified deletion request, except where we're required to retain records (e.g. payment records) for legal or tax purposes.
Security: passwords are stored as one-way hashes, never in plain text. We follow reasonable security practices, but no online service can guarantee absolute security.
Cookies: used only for session management (staying logged in). We do not currently use third-party advertising or tracking cookies; if that changes, this policy will be updated first.
Minors: this service is not intended for users under 18, and we do not knowingly collect data from minors.
Last updated: 12 Nov 2026. We may update this policy from time to time; material changes will be reflected here.
The service: OptionStrategyBuilder.in is a calculator that computes and displays option strategy figures. Nothing on this site is investment advice, a recommendation, or an offer to buy or sell any security. You are solely responsible for your own trading and investment decisions.
Eligibility: you must be at least 18 years old and able to form a binding contract to use this service.
Your account: you're responsible for keeping your login credentials secure. We may suspend or terminate accounts that violate these terms, are used abusively, or attempt to circumvent site limits.
Pro plan: a one-time payment of ₹299 grants 30 days of Pro access from the date of payment. It does not auto-renew or auto-charge — you must make a new payment to continue after it lapses. Pricing and duration may change for future purchases; an already-active Pro period is unaffected by later price changes.
Limitation of liability: the service is provided "as is," without warranty that figures are error-free, uninterrupted, or suitable for any particular purpose. We are not liable for any trading or investment losses arising from use of this site.
Prohibited use: you may not scrape, reverse-engineer, or use automated tools against this site, or resell or redistribute data obtained from it, without our written permission.
Ownership: the platform, its code, design, and the 44-strategy library remain our property. You retain ownership of the specific strategy configurations you build and save.
Governing law: these terms are governed by the laws of India, and any disputes are subject to the jurisdiction of the competent courts of India.
We may update these terms from time to time; continued use of the site after a change constitutes acceptance of the updated terms.
The Pro plan is a one-time payment for 30 days of access — there is no subscription, no auto-renewal, and no recurring charge to cancel.
Charged in error or payment succeeded but Pro didn't activate: contact support within 7 days of the charge with your payment reference (visible on your account page after a successful payment). If we confirm the error, we'll either activate/extend your Pro access or issue a refund to your original payment method, processed via Razorpay within 5–7 business days of approval.
Change of mind: since Pro access is granted immediately on payment, we don't offer refunds for change-of-mind once access has been activated.
For any refund request, email support@optionstrategybuilder.in with your registered email and payment reference.
