QuantumCat/For Zerodha
For Zerodha · Kite Connect · early access
Everything Zerodha does. Plus the tools it doesn't.
QuantumCat is a professional-grade cockpit that runs on top of your own Zerodha account through the official Kite Connect API. It doesn't replace Zerodha — it replaces the six tabs around it: order-flow detection, one-keystroke risk-sized orders, fill preview for your exact size, an honest backtester, and the market intel pros keep on a second screen.
Real build · Zerodha account
No new demat. No funds with us. Zerodha executes every order under your own credentials.
01 / Your Zerodha account
Your Zerodha account. A full trading cockpit on top.
QuantumCat is built for people who take the market seriously. Same broker, same account, same safety — everything Kite gives you, plus the tools no broker does, connected through the official Kite Connect API.
Charts
1-second candles
TradingView Advanced Charts down to 1-second bars built live from Zerodha's tick stream — resolution your broker's own charts don't give you.
Fill preview
See your fill before you take it
QuantumCat walks the depth ladder for your exact size and shows the average price and slippage you'd actually eat — before you press buy. Priceless on illiquid strikes.
Keyboard
One-keystroke orders
B/S to flip side, 1–5 for your five saved lot sizes, ⏎ to fire — your quantity pre-loaded before you even think about it.
Sessions
Automated daily login
Zerodha's API session expires every morning. QuantumCat handles the daily Kite login for you, so your bots, alerts and exits are live at 9:15 without you re-authenticating by hand.
Sizing
Size by risk, not by guess
Type the ₹ you're willing to lose and the stop distance — the ticket computes the lots, and margin updates live as you change it, red before the broker would reject you.
Tape
Your own tick archive
From day one, the terminal records every tick it streams to your own disk — powering tick-verified backtests, 1-second history and market replay. It compounds every session you run.
Pulse
Order-flow detection
Pulse reads the tick-by-tick microstructure of your Zerodha feed and shows the evidence — aggressive buying vs selling — trade by trade. It never tells you what to do; you decide, you own the risk.
Backtest
An honest backtester
Signals evaluate on closed candles and fill at the next bar's open, stops take priority inside the bar, and every simulated trade pays estimated Indian charges. It won't flatter you — paper-trade before going live.
Replay
Market replay
Play any recorded session back at 1× to 300× — price path, session VWAP, scrub bar. Practice the open twenty times before you trade it once. Replay never touches the order engine.
02 / Your keys
Your keys never leave your machine.
QuantumCat has no servers in the trade path. Your Kite Connect API keys live in your OS keychain (or an encrypted vault on your own server for the web app); orders travel from your machine straight to Zerodha. Your money and securities stay with your broker — you are never the product.
