Hi Team, @Tradehull_Imran

We are getting an exception for get_ltp_data function after updating Dhan_Tradehull 3.1.2 version

Error: Exception at calling ltp as {‘status’: ‘failure’, ‘remarks’: {‘error_code’: None, ‘error_type’: None, ‘error_message’: None}, ‘data’: ‘’}

@Tradehull_Imran Sir if i want get a particular candle based on the time then how do i do it?

[Tradehull_Imran]

Hi @Prasad_Magar ,

Yes do share the details.

[Tradehull_Imran]

Hi @Harry ,

You can resample the data. Firstly fetch 1min timeframe data and use in the below function -

tsl.resample_timeframe(df, timeframe='2T') # for 2 min data

Hi @Surendra_Singh1 ,

The access token might be expired, do regenerate the access token and try again.

[Surendra_Singh1]

Hi @Tradehull_Imran sir

code - ltp_data = trading_session.get_ltp_data(names=symbols)

If the access token has expired, it should have an impacted on other functions like get holdings, intraday data etc but i am getting exceptions only for get_ltp_data function after updating Dhan_Tradehull 3.1.2 version

Error: Exception at calling ltp as {‘status’: ‘failure’, ‘remarks’: {‘error_code’: None, ‘error_type’: None, ‘error_message’: None}, ‘data’: ‘’}

Hi @Tradehull_Imran Sir,
I want to calculate the “maximum profit”, and “maximum loss” from basket orders using Python before placing live trades.
And,
is there a way to caluclate “overall margin, final margin”
using python

[Tradehull_Imran]

Hi @Harry ,

Refer the below code-

data  = tsl.get_historical_data(tradingsymbol = 'TCS',exchange = 'NSE' ,timeframe="1")
data["timestamp"] = pd.to_datetime(data["timestamp"])
candle_data = data.loc[data["timestamp"] == pd.Timestamp("2026-01-30 15:25:00+05:30")]

[Tradehull_Imran]

Hi @Surendra_Singh1 ,

We will check on this.

[Tradehull_Imran]

Hi @Rakesh_Durgam ,

Use this formula for max profit and loss calculation
For basket order margin, Dhan is already building it will update once live.
Tagging @Dhan for same.

@Hardik @Tradehull_Imran sir

[vedvishwa]

After running the below command in cmd:

pip install Dhan-Tradehull

I developed the following script in sublime text:

@vedvishwa

import pandas as pd
import pdb
import time
import datetime
import traceback
from Dhan_Tradehull import Tradehull
from pprint import pprint
import talib
print(‘Hello’)

but,
I am facing below error upon execution…

What could be the wrong here??

Has it got anything to do with Dhan trading because, i don’t have a trading account with Dhan yet.

[Tradehull_Imran]

Hi @vedvishwa ,

Do refer the below thread and follow all the steps and update -

Thank you sir

Hi @Manish_M ,intraday_minute_data() requires additional parameters mentioned in errors - from_dat and to_date.These two parameters are required for calling a function
