01 · The idea

Everything a broker’s platform gives you. Plus the tools no broker does.

QuantumCat is not a broker and does not want your money. It is the cockpit that sits on the account you already have — every tick recorded to your own disk, every order sent from your own machine, every claim on this page shown on the real build.

PULSE

Big money leaves footprints. Pulse reads them.

When size works a position, the tape, the book, the option chain and the futures basis all bend in small, measurable ways. Pulse runs eight live detectors over your own feed and fuses them into one −100…+100 read — with the breakdown of why, every second.

  • Eight trails, one score. Delta divergence, effort vs result, OI pulse, IV skew tilt, tape anomaly, depth persistence, basis richness, VWAP anchor — each with its own confidence.
  • Hysteresis, not flicker. NEUTRAL flips to BULLISH only when the score holds above +35 for a sustained window, and exits at +15. A one-second spike can never flip the state.
  • A plan, in prices. Every confirmed flip freezes an entry reference, an invalidation and an objective — shadow-graded against what the market did next, so the live record is on screen before you trade.
  • Decision support, not advice. Pulse never tells you to buy or sell. It shows what the plumbing is doing; the trade, and the risk, are yours.

Hysteresis · drag the score0NEUTRAL
−100flip past ±35 · exit inside ±15+100

The state flips only past ±35 and holds until the score falls back inside ±15 — a one-second spike can’t flip it. The live engine also requires the score to hold there for a confirm window.

CHAIN

A chain you can trade from.

Every strike carries what you actually decide on — LTP, spread, OI and its change since the previous close, IV, and per-strike greeks — all off your own broker’s tick feed.

  • Greeks off the chain’s own IV, priced with Black-76 so they agree with the premiums beside them, not a textbook curve.
  • Depth to the level your broker serves — the 20×2 ladder where the broker’s own metadata says it exists (Dhan today), never five levels padded into twenty.
  • An unpriced strike shows “—”, never ₹0.00. The cell abstains and says why on hover.

STRATEGY

See the trade before you take it.

Compose any multi-leg structure and see the expiry payoff and the T+0 curve instantly — breakevens, max profit, max loss, and how the position breathes as spot, time and IV move.

  • Black-76 on the forward, with live IV — greeks per leg and for the whole structure, the way index options are actually priced.
  • Margin before you commit: basket margin with hedge offsets from your broker, beside the max-loss number.
  • Baskets that survive reality. Filled legs are never re-placed after a partial failure; buys sequence before sells where margin demands it.

BOTS

Bots that can explain themselves.

A bot is a strategy document — universe, timeframe, entries, exits, risk — compiled to a strict intermediate form and executed by a runtime where the same condition tree gives the same verdict in the bot, the screener and the backtester.

  • Closed candles, rising edges. A condition that is merely true doesn’t trade; it has to become true while the bot watches.
  • Three-valued logic. A warming-up indicator is UNKNOWN — it never fires an entry and never satisfies a NOT.
  • Paper first, reconciled every cycle. Paper fills cross the spread honestly; live bots reconcile against the broker’s book before anything re-fires.
  • The X-ray. Every leaf’s live value, the gate that’s holding it, a log of every decision. “Why didn’t it trade?” has a real answer.

SCREENER

Scanned, or named as not scanned.

Most screeners silently skip what they can’t compute and call the result complete. This one is built on the opposite contract.

  • Every symbol is either scanned or reported by name in the footer — errors, time-outs and instruments your feed broker doesn’t carry are never presented as “didn’t match”.
  • Own-chain option metrics: PCR, max pain, ATM IV — each instrument screened against its own chain.
  • An alarm that keeps ringing. Arm it on a saved screen and a new entrant rings until a human silences it.

JARVIS

Talk to your terminal. It answers — and acts.

JARVIS has the full run of the app through audited tools: it reads your book, runs screeners and backtests, builds bots, stages orders for your confirm and can diagnose the app itself — on your own ChatGPT plan, on your own machine.

  • 181 tools, every one visible in the transcript with its arguments and result. Nothing happens behind your back.
  • Staging by default. It fills your normal ticket and leaves it for you. Hands-free trading needs you to type ARM with caps — orders, size, a loss cap and a timer.
  • No path to your keys. The tools that could read credentials or change risk limits aren’t in its toolbox, so there is nothing to work around.
  • Runs on your subscription. No QuantumCat AI server, no per-token bill, no stored login — you sign in on ChatGPT’s own page.

TAPE & REPLAY

Your own tick archive, from day one.

The terminal records every tick it streams to your own disk. It compounds every session you run — and it is what makes the seconds chart, tick-verified backtests and market replay possible.

  • 1-second candles built live from the same tick stream your orders route against — on TradingView’s chart, on your broker’s tape.
  • Replay any recorded day tick by tick at 1× to 300× — pause, scrub, rehearse the open twenty times before you trade it once.
  • A backtester built to disappoint you honestly: signals on the close, fills on the next bar’s open, stops first inside every bar, every trade paying estimated Indian charges.
  • Refusal over fantasy. A strategy that depends on data the sim can’t reproduce refuses to run — with the reason.

INTEL

Who’s behind the move, and what’s scheduled to hit it.

Price tells you what happened. Intel tells you who was behind it and what is on the calendar — one view from the ticket, sourced from NSE’s own publications and your own feed.

  • FII/DII streaks, accumulated day by day into your own archive, with index-futures positioning drift tracked separately.
  • Options radar with IV rank against a history the terminal records for you, per underlying, from install day.
  • Breadth and sector heat computed from live constituent ticks on your own feed — rotation visible while it happens.

RESEARCH & INVESTING

Take apart the company, not just the candle.

The same terminal that sizes a scalp reads NSE’s own filings. The Company Report is a six-dimension teardown of any listed company; Investing runs seven explicit rules over a universe you choose and turns one list into a whole-share allocation for a real budget.

  • Absent is never zero. A field the filer did not disclose prints an em-dash, not ₹0 — and every scored pillar carries the percentage of its own inputs that were actually filed.
  • Every number is one click from its filing. Each quarter carries the XBRL document it was parsed from, and every red flag carries its evidence inline.
  • A reverse DCF, not a target price. It tells you what growth the current price is already assuming, set against what the company has delivered over three and five years.
  • Candidates with their reasons. Every Investing row shows the scanned number against its threshold, when it was scanned, and how much of the universe the pass could actually judge — then the explorer turns the list into whole shares inside a budget, and places nothing.

QUOTE RADAR

When quotes stop adding up.

A call and a put at one strike imply the future. A butterfly cannot be worth less than nothing. Six detectors watch the chain for prices that cannot all be right at once — and report them in rupees, net of the whole Indian charge stack.

  • Net of brokerage, STT, exchange, SEBI, GST, stamp and DP. A gross discrepancy the charge stack eats never reaches the screen.
  • Every switch carries its own record. Of everything a detector ever found, how much was still there thirty seconds later — and a detector that stops surviving demotes itself.
  • Observe mode is the default. Cards display and journal; staging is hidden. Even with it off, the radar only pre-fills the payoff builder — the armed human confirm is the one and only trigger.
  • The decision casebook. Every retained read, with its original evidence and whatever outcome followed — because a tool that forgets its own calls will always look like it works.

05 · Discipline

Rules you write while calm, enforced when you aren’t.

Speed without rails is a faster way to lose money. Sizing, protection and the kill switch are one system, enforced in the shared Rust order engine — the same code the ticket, the chart overlays, the bots and the assistant all route through.

The kill switch armed from the terminal header, cancelling working orders and flattening every position.
Kill switch · real build0:11

The kill switch

One control, everywhere — including a global hotkey.

Stop every bot, cancel all working orders, sweep standing GTTs, then square off every position across all logged-in brokers — and verify flat by re-reading the book until it’s confirmed, escalating to marketable prices if an exit rests unfilled. It reports INCOMPLETE loudly rather than pretending.

A cap never blocks an exit. Reduce-only orders, square-offs and the kill switch bypass the entry gate entirely. You can always get out.

Sizing

Size by risk, not by guess.

Type the rupees you’re willing to lose and the stop distance — the ticket computes the lots, capped by your per-order ceiling. Margin updates live, red before the broker would reject you, and the depth ladder shows the price your quantity would actually clear.

Protection

Stops that survive your laptop.

OCO brackets, break-even and trailing stops as broker-side standing triggers wherever the broker supports them. Every trail move is verified by reading the trigger back — the UI never claims a stop moved when it didn’t.

Breakers

Circuit breakers over your own discipline.

Loss streaks, overtrading pace, size versus your baseline, time of day. When one trips it warns, cools off or locks new entries — and disabling the rule does not lift a live cool-off. That is the point of writing it while calm.

07 · Questions

Answered straight.

Is QuantumCat a broker?

No. QuantumCat is a terminal that connects to your existing broker account through that broker’s official public API. Your money and securities stay with your broker; every order is executed by them under your credentials.

Do my keys or orders ever touch QuantumCat’s servers?

No — there aren’t any in the trade path. API keys live in an encrypted vault on your own machine. Orders travel from your machine to your broker, full stop.

Which brokers work today?

Zerodha (browser sign-in, including automated daily login), Dhan (access token — and the only one serving 20-level depth today) and Angel One (client code, MPIN and TOTP) all ship today, and Groww (Trade API: cash and F&O on NSE/BSE, daily key approval on Groww’s side, prices polled once a second, no broker-side standing orders yet) ships in beta. Each is modelled as it actually behaves, so a control a broker doesn’t support is disabled with the reason rather than silently ignored. Upstox and Fyers are next. See brokers & sessions and the setup guide.

What happens to my stop-loss if my laptop dies?

Nothing bad — that’s the point. OCO brackets and break-even stops are standing triggers (GTT) on your broker’s servers, not in the app. Two honest caveats your broker also states: a trigger fires once, and a triggered order isn’t guaranteed a fill any more than any other order. The only piece that needs the app running is the trailing advance — if the app closes mid-trail, the last planted stop keeps protecting you at the broker. Every feature is labelled broker-side or app-side so you always know which guarantee you’re holding.

Can I trust the backtester?

You can trust it not to flatter you. Signals evaluate on closed candles and fill at the next bar’s open, stops take priority inside each bar, and every simulated trade pays estimated Indian charges. If a strategy depends on live-only data the replay can’t reproduce, it refuses to run and says why. It’s still a simulation — treat results as directional, and paper-trade before going live.

Is the Company Report or Investing a recommendation?

No. The Company Report reads what companies filed with the exchange and shows you the arithmetic — including the arithmetic it could not do, named as such. Investing runs seven explicit rules you can read and edit, and prints the scanned number that made each candidate qualify beside it. Neither ranks the market, picks stocks or tells you what to own, and the portfolio explorer places nothing: its only bridge to trading writes a paper-mode strategy into Bots, which you start yourself. See the Company Report and Investing.

Is QuantumPulse investment advice?

No. Pulse measures what is happening in market microstructure and shows you the evidence trail by trail. It never recommends a trade, and it can be wrong — markets don’t owe anyone a pattern. You decide, you own the risk.

Does JARVIS place trades on its own?

Not unless you tell it to. Normally it fills in your order ticket and leaves it for you to send — same checks, same confirm button as always. Hands-free trading is something you switch on by typing ARM with limits: how many orders, how big, a loss cap and a timer. It forgets all that when you close the app, and the kill switch stops it. It also has no path to your keys or risk settings — those aren’t things it is able to do.

Do I have to pay extra for the AI?

No — but you need your own ChatGPT Plus or Pro plan. It runs on your subscription, on your machine. We don’t charge for the AI, don’t store your login, and there’s no server passing your requests around. No ChatGPT plan just means no assistant; everything else works exactly the same.

What about exchange rules for automated orders?

Bots place orders through your broker’s official API within the broker’s rate limits, and paper mode is the default. Depending on your broker and strategy, exchange algo regulations may apply to you — read your broker’s API terms, and when in doubt, ask them. QuantumCat gives you the tools; compliance with your broker’s terms is yours.
