“Sir, just like you had the option for client login and API key in your dhan_websocket, I don’t have that option in my app. Can you please explain why?”

Hi @sgoogal

As of now the code is fixed for windows users, we will release codebase with MAC compatibility in upcoming release.

Till then you may proceed with any windows machine or server

Hi @Md_Naquibuddin
Yes its mandatory to subscribe to the dhanhq api to get the data

Tradehull_Imran · October 19, 2024, 9:13am

Hi @Abhishek_Konda

Yes for the data, subscribing to paid dhanhq api is mandatory

Tradehull_Imran · October 19, 2024, 9:18am

hi @Md_Naquibuddin

the screenshot of the code provided is of Dhan_websocket.py, we need to make the changes in line no 41 and 42… access_token line.. and the client_code line

Also you need to make changes in Dhan_codebase usage.py, in the client_code and token_id variable

Md_Naquibuddin · October 19, 2024, 9:43am

When we try to enter the codebase, this message appears. Why?"

@Tradehull_Imran Sir, you teach us Python in the simplest way possible, making it easy to understand. You also point out our mistakes and guide us on how to become independent in coding (algorithmic coding/Python/programming) through the debugging process. The best part is your constant motivation and encouragement, congratulating us on our efforts, even though the credit truly goes to you. I know teaching to someone with simple way is not the simplest at all. It’s requires lot of hard word and research.

Thanks @Dhan
