sir what is this invalid syntax
Hi @Shreeshant_Chikane ,
Do run the following commands to check python version -
python --version
If its version is less than 3.12 then follow the steps in this link to upgrade -

Hi @Shreeshant_Chikane ,
The issue appears to be caused by invalid credentials. Kindly verify the Client ID , PIN , and TOTP , and then run the code again. It should work without any errors once the correct credentials are provided.
@Tradehull_Imran I know generic issue but stil lface issue File “C:\Users\Dell\AppData\Roaming\Python\Python314\site-packages\Dhan_Tradehull\Dhan_Tradehull.py”, line 61, in init
raise Exception(“Login failed. Please retry with valid credentials.”)
Exception: Login failed. Please retry with valid credentials.
client_code = “Taken from Dhan”
pin = “we know 6 digits password to login”
totp_secret = “Enabled with Authenticator code and copied the same line under scanner”
Hi @Alok_Kulkarni ,
Change the totp key again. Try it with new totp key.
Thanks! I was getting that error — looks like I need to enable the API for this. However, I just wanted to confirm: why do we need to instruct Cursor to build this for me? Can we run any Python script to produce output like the one below, in the same terminal?
Login succeeded for client xyz, but every stock still fails with DH-902 — Data APIs are not active on this account.
No share prices were returned. Confirm the Data API plan is active on this client ID at web.dhan.co → My Profile → DhanHQ Trading APIs, or put the subscribed account’s credentials back in the file and I’ll run again.
Hi @Alok_Kulkarni ,
Yes, Cursor AI can create a Python script that reads the Dhan API error and displays a clear message like this in the same terminal. The output will be generated based on the actual API response.

When I run command manually on cursor terminal i.e. python Demo Algo.py then I am getting above error. However, when I gave commnd on Cursor right pane i.e. “Please build code for me” then its connecting and showing buy and sell signals as you have shown in vedio. Just wanted to know why there such difference ? Am I missing out anything here…
Hi @Alok_Kulkarni ,
This is mainly due to an SSL/certificate configuration difference between the Python environments. The manual terminal and Cursor may be using different Python interpreters.
Refer this command and try running this -
python -m pip install --upgrade certifi requests urllib3 scipy
Also make sure Cursor and the terminal are using the same Python interpreter.

Can you tell us how to install in mac.
Hi @Muthu_Mani ,
Dhan_Tradehull Library Update — macOS
The updated Dhan_Tradehull codebase requires Python 3.10 or higher. Python 3.12 is recommended for this version.
Note: These steps are specifically for macOS. No virtual environment is required.
Step 1: Download the Required Files
Use the original Google Drive shared by Tradehull:
Installation Files:
Google Drive — Dhan_Tradehull Files
The original MadeForTrade post provides this Drive for the required installation files.
Download the required files to your Mac.
Step 2: Check the Existing Python Version
Open Terminal and run:
python3 --version
Also run:
which python3
If Python 3.8 or another older version is being used, install Python 3.12 as described below.
Step 3: Install Python 3.12
Option A — Recommended: Homebrew
If Homebrew is already installed, run:
brew update
brew install python@3.12
Homebrew currently provides Python 3.12.14 for both Apple Silicon and Intel Macs.
Verify the installation:
python3.12 --version
Expected:
Python 3.12.x
If Homebrew is not installed
You can install Python directly from the official Python website:
Python 3.12 for macOS — Official Downloads
The official Python macOS downloads include Python 3.12 releases with a 64-bit universal2 installer, suitable for supported Intel and Apple Silicon Macs.
Step 4: Make Python 3.12 the Default Python
Apple Silicon Mac — M1/M2/M3/M4
Run:
echo 'export PATH="/opt/homebrew/opt/python@3.12/bin:$PATH"' >> ~/.zshrc
source ~/.zshrc
Intel Mac
Run:
echo 'export PATH="/usr/local/opt/python@3.12/bin:$PATH"' >> ~/.zshrc
source ~/.zshrc
Now verify:
python3 --version
and:
which python3
Make sure Python 3.12 is being used.
Step 5: Upgrade pip
Run:
python3 -m pip install --upgrade pip
Verify:
python3 -m pip --version
Step 6: Install Dhan_Tradehull
Install the updated library using:
python3 -m pip install Dhan-Tradehull
Verify the installation:
python3 -m pip show Dhan-Tradehull
You can also check the installed DhanHQ dependency:
python3 -m pip show dhanhq
The original post points users to the Dhan-Tradehull PyPI package for the updated functions and usage.
Step 7: Install the Required Libraries
If the Google Drive contains an install libraries.bat file, do not try to execute the .bat file on Mac.
.bat is a Windows batch file.
Instead, if your project contains a requirements.txt, open Terminal in the project folder:
cd /path/to/your/project
Then run:
python3 -m pip install -r requirements.txt
If the shared Drive contains a list of required libraries but no requirements.txt, install those packages manually using:
python3 -m pip install <package-name>
Step 8: Verify Dhan_Tradehull
Run:
python3 -c "from Dhan_Tradehull import Tradehull; print('Dhan_Tradehull installed successfully')"
Expected:
Dhan_Tradehull installed successfully
Step 9: Download the New Login Methods File
The original Tradehull post provides a separate Google Drive file called:
login_methods.py
login_methods.py — Google Drive
Download the login_methods.py file from the Drive provided in the original post and place it in your project according to the structure used by the updated codebase. The post specifically identifies this file as the reference for the new login methods.
Step 10: Configure PIN + TOTP Login
The updated library introduces additional authentication methods.
The important new method is:
PIN + TOTP authentication
This allows the application to generate the access token during login instead of requiring the user to manually provide a new access token every day.
Use the login_methods.py file provided by Tradehull as the reference for implementing this method.
Step 11: Run Your Existing Algo
Navigate to your existing algo project:
cd /path/to/your/algo
Run it using Python 3.12:
python3 your_algo.py
For example:
python3 main.py
Step 12: Final Verification
Run these commands:
python3 --version
python3 -m pip show Dhan-Tradehull
python3 -c "from Dhan_Tradehull import Tradehull; print('Tradehull OK')"
If all three work correctly, your macOS setup is ready.
The key point is: you can use the same Google Drive files from the original post on Mac, but you cannot use the Windows .bat installer directly. The Drive is just the file source; the installation commands need to be adapted for macOS.
Sir,
I want to backtest Index Options strategies which involve deep otm strikes.
-
How to download Hysterical options data for more than ATM+10 (deep OTM).
-
How to store the large data efficiently.
Please guide.
Hi @anjalik ,
For expired contracts, the Expired Options Data API supports ATM -10 to ATM +10 for index options on a rolling basis, while other contracts and expiries are limited to ATM -3 to ATM +3. Therefore, deeper OTM historical data beyond these ranges cannot currently be retrieved through the API.
The retrieved data can be stored in CSV files, organized by date, symbol, expiry, strike, or option type. For larger datasets, other storage formats or databases can also be considered.
