For Dhan · Official API · Early access
The order-flow terminal
for your Dhan account.
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, protection armed at entry, ratcheting stops, 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 day-trader's cockpit on top.
Dhan gives you the account and the execution. QuantumCat gives you the surface a scalper actually needs 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 — most broker charts stop at one minute. A scalper's exits live inside that minute.
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.
Protection armed at entry broker-side
The stop-loss and target sit on the ticket, not three screens away: arm the OCO in the same breath as the entry, with exit legs priced through the trigger so they fill across gaps instead of resting there.
Trailing stops that ratchet hybrid
The stop sits at Dhan; while the app runs it ratchets behind price — never backwards. If your machine dies, the last planted stop is still live at your broker. The honest version of trailing, labelled as such.
Auto-slice past the freeze limit
Size past the exchange freeze quantity and QuantumCat drips it fill-by-fill so you stay within the rules — you just type the quantity you actually want.
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.
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.
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.
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.
