Connect Dhan to AlgoCrab — Complete Setup Guide

Dhan + AlgoCrab overview

Dhan’s developer stack (DhanHQ) is popular with active F&O traders. AlgoCrab integrates Dhan for connect, orders, positions, holdings, funds, historical data, and live market data — one of the more complete broker implementations on the platform.

Unlike Zerodha’s OAuth redirect, Dhan connection is typically token-based: you provide Client ID and Access Token from the Dhan developer portal.

Prerequisites

Active Dhan trading account with API access enabled.

Client ID and Access Token from Dhan’s developer documentation / portal (see https://dhanhq.co/docs/latest/).

AlgoCrab account ready to open Connect Broker → Dhan.

A plan for token refresh if Dhan rotates access tokens on a schedule — expired tokens stop live algos.

Step 1 — Create DhanHQ credentials

Log in to Dhan’s developer section and create or view your API application.

Copy Client ID and generate/copy the Access Token as per Dhan’s latest UI.

Store tokens offline. Never embed them in public TradingView scripts.

Step 2 — Connect Dhan inside AlgoCrab

Go to Connect Broker → Dhan.

Paste Client ID and Access Token into the form. Screenshot placeholder: [Screenshot: AlgoCrab Dhan connect form].

Submit and wait for a successful connection state.

No OAuth browser hop is required for the standard Dhan token flow on AlgoCrab.

Step 3 — Verify the connection

Open Broker Panel: confirm funds/margin.

Load order book and positions — empty books are OK.

Optional: place and cancel a safe limit order to confirm routing.

Step 4 — First strategy on Dhan

Backtest a simple options or futures rule on liquid index instruments.

Enable stop-loss / target fields before Start.

Start with minimal lots. Watch rejects related to margin or freeze quantity.

Dhan’s modify-order support on AlgoCrab helps when you need controlled amendments — still prefer strategy-level exits over manual chaos.

Common errors and fixes

401 / auth failures: Regenerate Access Token and reconnect.

Rate limits: Reduce parallel strategies or polling intensity.

Symbol mapping issues: Select instruments via AlgoCrab search so Dhan tokens map correctly.

Historical fetch timeouts: Large history jobs can take time; retry off-peak if needed.

FAQs

Q: Is Dhan better than Zerodha for algos? A: Depends on brokerage, margins, and your workflow. AlgoCrab supports both — compare brokers, not just platforms.

Q: Can I run Dhan and Zerodha together? A: Yes. Multi-broker is a core AlgoCrab use case — connect both and assign strategies carefully.
