Thanks@Imran,

After modifying to chart = tsl.get_historical_data(stock_name, ‘NSE’, 15) .

Now i am getting below error

-----Logged into Dhan-----

Also can you share me systax code for indicator CCI instead of RSI.

Hi @Krushna_Rout ,

Do share the code.

3550

Hi @Krushna_Rout ,

Do upgrade the codebase version you are using.

We’ve made several improvements to the Dhan_TradeHull codebase, and here’s a quick overview of what’s new:

  1. Long-term historical data
    You can now pull multi-year data easily using:
data = tsl.get_long_term_historical_data(
    tradingsymbol="NIFTY",
    exchange="NSE",
    timeframe="5",
    from_date="2022-01-01",
    to_date="2025-12-03"
)
  1. Sector-wise historical data (Intraday)
    This helps when analysing broader market sectors.
data = tsl.get_historical_data("NIFTY 100", "NSE", timeframe="1", sector="YES")

data = tsl.get_long_term_historical_data(
    tradingsymbol="NIFTY 100",
    exchange="NSE",
    timeframe="5",
    from_date="2022-01-01",
    to_date="2025-12-03",
    sector="YES"
)
  1. Expired options data
    You can now fetch historical option data even after expiry.
data = tsl.get_expired_option_data(
    tradingsymbol="RELIANCE",
    exchange="NSE",
    interval=1,
    expiry_flag="MONTH",
    expiry_code=1,
    strike="ATM",
    option_type="CALL",
    from_date="2024-10-10",
    to_date="2024-11-10"
)
  1. Market depth data for multiple instruments
    Useful when you need full-depth snapshots for different symbols.
symbol_list = [
    ("RELIANCE", "NSE"),
    ("NIFTY 09 DEC 26000 CALL", "NFO"),
    ("NIFTY 09 DEC 25500 PUT", "NFO")]

depth_data = tsl.full_market_depth_data(symbol_list)

for key, depth_client in depth_data.items():
    bid_df, ask_df = tsl.get_market_depth_df(depth_client)

  1. Fetching historical Data for 90 days
    The tsl.get_historical_data() function is now updated to return candle data for the past 90 days.

  2. Strike selection issue fixed
    Strikes for symbols now resolve correctly without mismatch.

To use all these updates:

• Install the required dhanhq version

pip install dhanhq==2.1.0

• Upgrade to the latest Dhan-Tradehull

pip install --upgrade Dhan-Tradehull

• Confirm the version’s for dhanhq if 2.1.0 and Dhan-Tradehull is 3.1.2

pip show dhanhq
pip show Dhan-Tradehull

Getting this, it started all of a sudden though token is newly created
@Tradehull_Imran @Tradehull_Priya
I hope it’s not related to new versions.

3554

Hi @Krushna_Rout ,

The code seems to be working fine, do retry after sometime. Once also regenerate the access token-

3555

Hi @Rajashekhar_Rangappa ,

This error is not caused due to new version, regenerate the access token and retry once more.

3556

Sorted. Not sure what was the issue.

one more, Exit check failed for SENSEX_DEC_FUT_PUT: ‘NoneType’ object has no attribute ‘iloc’

3557

Hi @Rajashekhar_Rangappa ,

Could you elaborate your query?

3559

Hi@Imran,

I am getting below error while while running 13. option buying algo.I think few codes have been updated since last year in dhan trade hull but your lecture session codes ,old coding is available. Is it possible ,your team can update with proper syntax.

ie all_ltp = tsl.get_ltp_data(names = watchlist) is not taking so we need to update as all_ltp = tsl.get_historical_data(tradingsymbol = name,exchange = exchange,timeframe=“15”).

Can you guide for below errors: why its asking ‘qty’

watchlist = ['NIFTY','360ONE','ABB','ABCAPITAL','ADANIENSOL','ADANIENT','ADANIGREEN']

    			exchange = "INDEX"

    			exchange = "NSE"
    			all_ltp = tsl.get_historical_data(tradingsymbol = name,exchange = exchange,timeframe="15")

	    		# pdb.set_trace()

Hi @Krushna_Rout ,

The ltp can be fetched using the below code, it is not required to use tsl.get_historical_data(tradingsymbol = name,exchange = exchange,timeframe=“15”) function to fetch ltp-

   data = tsl.get_ltp_data(names=['CRUDEOIL', 'NIFTY'])
   crudeoil_ltp = data['CRUDEOIL']

Kindly refer the below documentation to check the updated functions-

Can you check for me, plz?

  1. self.tsl.ATM_Strike_Selection(‘SENSEX‘, 0)

  2. self.tsl.get_historical_data(“SENSEX DEC FUT”, “BFO”, “5”)

    both are failing in latest release

3562

Hi @Rajashekhar_Rangappa ,

If you encounter an exception where error_message is None, please restart the application or regenerate the access token and try again.

3563

Hi @Tradehull_Imran

Thank you for your reply,

In the above queries,can be tell me ,why i am getting ‘qty’ only?

3564

Hi @Krushna_Rout ,

The code you have shared seems to be incomplete, do share complete code to review.

3565

Yep. working. May I know the reason behind failure?
