Pricing and Payments
Effective 2 October 2026
Almost everything on DeltaK is free. Two things cost this service real money each time they are used, replays and screener questions: those come with a free week, and past it you can buy a single use, top up Credits, or take a plan and stop counting.
Free
The market walls, the option chains with Greeks, the strategy builder, every instrument page, the signal engine on Copilot, the paper wallet, profiles and friends, the Backtest wall's featured runs with every trade and a PDF of each report, and the whole learning wiki. No allowance, no price. On top of that, every week:
- 7 replay sessions (one instrument, or one index expiry, on one past day) and 20 screener questions in plain English — reset every Monday at 00:00 IST.
- 1 watchlist, your latest 3 screens kept automatically, and 3 alerts by email.
A replay session you have already opened is never charged again, and a screener question that fails to compile is returned to you automatically.
Plans
| Plan | 30 days | 1 year |
|---|---|---|
| Pro — unlimited replays and screener questions, 3 watchlists, every screen kept, 25 alerts by email and Telegram | ₹499 | ₹4,999 |
| Premium — everything in Pro, plus Autopilot (the engine takes its own paper trades, all session, on every wall), 5 watchlists and 100 alerts | ₹1,499 | ₹14,999 |
- Prepaid, not a subscription. You pay once through checkout for 30 days or a year. Nothing renews by itself and nothing is ever charged automatically. We email you three days and one day before a plan ends, and the markets dashboard shows a notice.
- Paying before a plan ends starts the next period where it stops, so no day is lost. Upgrading from Pro to Premium starts Premium at once and moves any Pro time left to after it.
- Fair use on an unlimited plan is 40 replay sessions a day. Past it, a replay uses your free week, single uses or Credits, as on Free.
- Autopilot trades on paper only. DeltaK never places a real order with a broker, on any plan. If Premium lapses, Autopilot steps back to Copilot and nothing already open is closed or changed.
- When a plan ends nothing you made is deleted. Lists and kept screens past the free limits stay readable.
Backtests
The featured backtests on the Backtest wall are recorded runs, so they cost nothing to open however often you open them, on any plan. A backtest of your own rules — a sentence you type on the wall, which the backtest agent reads, runs and may run a few variants of to answer — is one test, priced as below.
| Plan | Included | Past that, each test |
|---|---|---|
| Free | 1 a week | ₹19 |
| Pro | 5 a week | ₹10 |
| Premium | 10 a day | ₹10 |
Weeks reset every Monday at 00:00 IST and days at midnight IST. A test past what is included is paid from your Credits and only with your say-so — the price is shown before anything is spent — and a test that fails to run is returned to you.
Structure readings
“Analyse” on an instrument's chart asks a model to read the daily Structure Map and suggest any swing setup it can justify. A reading already asked for that day by anyone is shared and costs nothing; a fresh one counts against your plan, and nothing past that is charged.
| Plan | Fresh readings included |
|---|---|
| Free | 5 a week |
| Pro | 10 a day |
| Premium | 25 a day |
A school seat includes what Premium does. A reading that fails to come back is returned to you.
Single uses and packs
| Item | Price |
|---|---|
| 1 replay | ₹15 |
| 5 replays | ₹59 |
| 1 screener question | ₹2 |
| 25 screener questions | ₹39 |
| An extra watchlist on Free (up to 3 in all; the slot stays yours if you delete the list or a plan ends) | ₹29 once |
| Keeping a screen for good on Free (every screen is kept on a plan) | ₹5 once |
Single uses never expire and are spent before your Credits. Past the free week, a replay is ₹15 and a question ₹2 — the paywall offers the single one in a tap.
For schools and institutes
A school running a course on DeltaK pays for its own plan, from the partner area, once DeltaK has approved it. Its students pay nothing.
| Item | Price |
|---|---|
| The partner area — cohorts, invites, the school's reports | ₹4,999 for 30 days |
| Each student seat — everything in Premium while the school's period runs, with nothing paid by the student | ₹199 per student for 30 days |
| Seats added part-way through a period | ₹199 per seat, scaled to the days left |
Prepaid, GST included, and nothing renews by itself. Paying before a period ends starts the next one where it stops. See the partner page for a worked example.
Credits
A prepaid rupee balance underneath everything else: any metered use or one-time extra can be paid from it, each time with your say-so on screen. Credits do not expire.
| You pay | You get in Credits |
|---|---|
| ₹49 | ₹49 |
| ₹99 | ₹109 (includes ₹10 bonus) |
| ₹199 | ₹229 (includes ₹30 bonus) |
Referral Credits
Every account has an invite link. A friend who creates a new account through it gets ₹50 in Credits. When that friend first pays for anything, you get ₹100, and every 3 friends who pay also give you 30 days of Pro, added after any plan you hold. Referral Credits are capped at ₹2,000 per account. A referral must be a new account, on a different device from yours, with a regular email address, made within 30 days of opening the link.
How payment works
- All prices are in Indian rupees and are the amount you pay, including any applicable taxes.
- Payments are processed by Razorpay. Checkout opens on UPI; cards, net banking and the other methods Razorpay offers are available in the same checkout. DeltaK never sees or stores your card, UPI or bank details.
- A paid use is only charged after you confirm the price on screen, and nothing is ever charged automatically or on a schedule — plans included.
- A receipt is emailed to you for every payment. Credits can only be spent on DeltaK and cannot be cashed out or transferred — see the Terms.
- For cancellations, refunds and payments that did not go through, see the Cancellation and Refund Policy.
Prices may change. A change never affects Credits already in your balance, single uses you hold, or plan time already bought. An Autopilot pass bought before plans existed is honoured as Premium for the days it has left.
