Thank you

[IMRANUL_HAQUE_NOOR]

for me the error still remain even after downgrading to dhanhq 1.3.3

[rohit2312]

Hi Imran,

Please find the attached watchlist screenshot. It is still, LTP is not updating in this

[mrizzwanghazi]

hi @Kalpeshh_Patel
You can use your code during market hours… perhaps API is not sending you the data that’s why you are receiving this error.

[rohit2312]

Hi @Tradehull_Imran ,

I am doing with the video you have shared but not getting LTP in this.
Please find the attached screenshot for your reference.

[Tradehull_Imran]

Hi @Kishore007
this questions solution is solved,

see : https://youtu.be/HLiEpNZSD80?si=KP2N9O_Lc-m_maer&t=1940

[Tradehull_Imran]

Hi @Abhinav_Patil
It seems you are working with python 3.1.3, do use python-3.8.0

Since Twisted-20.3.0-cp38-cp38-win_amd64.whl is for 3.8 version specifically, that is why you are facing “not supported on platform”

[Tradehull_Imran]

Hi @Himansshu_Joshi
Trailing is added in upcoming todo videos.

[Tradehull_Imran]

Hi @Minakshi_Kuila

Dhan_websocket is a hard method to fetch LTP.
now we can fetch LTP easily using Dhan_Tradehull_V2.py

[Tradehull_Imran]

Hi @Sandip_Kumar

we now don’t need to use WebSocket to fetch LTP

Hi
Thanks
But during the market times also shows error

[Tradehull_Imran]

Hi @Kalpeshh_Patel
You may check the token issue.

If it works you will get data even in off market hours.

[Kalpeshh_Patel]

Hi
Which token should I use
Trading API or Data API
Although I tried with both API but not work
