For Dhan · Official API · Early access
Everything Dhan does.
Plus the tools it doesn't.
QuantumCat is a professional-grade cockpit that runs on top of your own Dhan account through its official API. It doesn't replace Dhan — 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.
No new demat. No funds with us. Dhan executes every order under your own credentials.
Your Dhan account.
A full trading cockpit on top.
Dhan gives you the account and the execution. QuantumCat gives you everything Dhan does and the tools it doesn't on top of it — and it labels every feature honestly, broker-side or app-side, so you always know which guarantee you're holding.
1-second candles
TradingView Advanced Charts down to 1-second bars built live from Dhan's tick stream — resolution your broker's own charts don't give you.
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.
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.
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.
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.
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.
Order-flow detection QuantumPulse
Pulse reads the tick-by-tick microstructure of your Dhan 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.
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.
A command bar that keeps up
⌘K takes commands, not just symbols: RELIANCE OI jumps to its chain, NIFTY PCR to positioning, TCS NEWS to its filings. The terminal keeps up with your hands.
Your keys never leave your machine.
QuantumCat has no servers in the trade path. Your Dhan API credentials live in your OS keychain (or an encrypted vault on your own server for the web app); orders travel from your machine straight to Dhan. Your money and securities stay with your broker — you are never the product.
