Hi @Praveen_Shanbhog

Use this link,
Also we have upgraded from python 3.8 to python 3.12 files for which are in this link

Also do watch this video for the updated codebase usage

Hello Imran,

I am currently at the same video. However, to learn Python I previously installed Python 3.13.7 and brackets to write code. And I tried to install the required libraries from the drive link as the post said “We have updated our codebase to align with the latest dhanhq library. To use this version, Python 3.10 or higher is required.”

However, the code is leading to the following error:

"Checking Python version: was

ERROR: Python version mismatch. This wheel requires Python 3.12.x

Waiting for 16 seconds, press a key to continue …"

How should I proceed from here? Can I use the current version and install libraries in a different way? Or should I uninstall and install accordingly to the drive links? I also tried to refer to the link “Dhan-Tradehull 3.2.1”, but dint know, how to proceed from here.

Also, so far, I have used brackets text editor for writing the python code for small projects, should I switch to Sublime Text?

Thank you.

Hi @vishnu_kolipaka ,

You can use Python 3.13.7 and install the required libraries accordingly.
Alternatively, refer to the provided link and install Python 3.12 using the .bat file available in the drive.

For writing Python code, you can use either Sublime Text or the Cursor app.

Thanks Imran,

I’m new to installing libraries. Could you share links/steps for required ones with Python 3.13.7?

Will it cause compatibility issues with the YouTube series code?

Tradehull_Imran · March 26, 2026, 4:46am

Hi @vishnu_kolipaka

Better is to uninstall python 3.13.7 as this verison does not support talib library which is necessary for creating indicators. Thus the ERROR: Python version mismatch. This wheel requires Python 3.12.x

Step1 : Uninstall python 3.13.7

Step2: Install python 3.12 with its libraries , for detailed steps see this link

Step3: For IDE with first preference use Cursor it has good AI support.

Let me know if this fixes it

@dhanpy Find the “token” id from the csv file and update your .env file with that.

How to view a continuous Gold chart on MCX?

MCX Gold trades in rolling 3-month contracts (Feb → Apr → Jun → Aug), each showing only ~3 months of data with price gaps at expiry — making long-term analysis and backtesting difficult.

Two questions:

1.Continuous chart — Individual contract charts end after 3 months with price gaps. How do I found a single continuous chart showing all historical data without interruptions?

2.Overlapping contracts — If a contract lasts only 3 months, how is the next expiry already visible and tradeable before the current one expires?

can someone help me with below error

@yat_2004 NIFTY 19 DEC is incorrect expiry.

yat_2004 · March 30, 2026, 10:51am

i tried with ACC and CIPLA as well it was still failing . just to let you know i am not coding guys so there is a chance i may make silly mistake

import pdb
import time
import datetime
import traceback
from Dhan_Tradehull import Tradehull
import pandas as pd
from pprint import pprint
import talib

client_code = “xxxxxxx” (removed for security reason )
token_id    = “xxxxxxxx” (removed for security reason)
tsl         = Tradehull(client_code,token_id)

pdb.set_trace()

all_ltp_data   = tsl.get_ltp_data(names = [“ACC”, “CIPLA”])
acc_ltp = all_ltp_data[‘ACC’]
#pe_ltp  = all_ltp_data[‘NIFTY 19 DEC 24000 PUT’]”

Copy paste your code in “Google AI mode” for quick fixes. Alternatively try official Python sdk here and docs here.

yat_2004 · March 30, 2026, 12:33pm

does it require DATA API subscription to get the LTP data or is it only required when we need to get historical data?

DSingh · March 30, 2026, 12:41pm

@yat_2004 Read here.

Rakesh_Durgam · April 1, 2026, 2:24pm

Hey @Tradehull_Imran

All API orders must come from a whitelisted static IP. Can you please tell me how to get static IP for AWS and how to setup?
