Hi @prathmesh_takale ,
Refer the below link from session2–
We’re still working on it — connecting with a few firms and finalizing the structure. We’ll also need to upgrade a few key skills to align with prop-quant requirement, like backtesting and some maths.

@akki Great to hear it 
Hi @Tradehull_Imran Sir,
I am getting TypeError: cannot unpack non-iterable NoneType object
if I use below code to fetch option chain
(Pdb) atm_strike,option_chain = tsl.get_option_chain(Underlying = ‘NIFTY’, exchange = ‘INDEX’,expiry=1,num_strikes=10)
Getting Error at Option Chain as ‘NIFTY’
*** TypeError: cannot unpack non-iterable NoneType object
also if I use
(Pdb) option_chain = tsl.get_option_chain(Underlying=“NIFTY”, exchange=“INDEX”, expiry=0, num_strikes=10)
then I get below error
Getting Error at Option Chain as ‘NIFTY’
Can you please suggest a solution over this.
Hi @ddeogharkar ,
The code seems to be working fine, make sure you are using the updated codebase.
Do update to our latest codebase version 3.0.6:
- Open Command Prompt: Press Win, type cmd, and press Enter.
- Install Dhan-Tradehull: Run
pip install Dhan-Tradehull - Confirm the installation by running
pip show Dhan-Tradehull
Guide to use the updated codebase:
Refer the below pypi link for more details:

Hi @Tradehull_Imran Sir,

Hi @Tradehull_Imran Sir ,
we are getting option greek (‘delta’) value wrong for weekly expiry strikes Nifty option chain
but we are getting correct value for stocks options with monthly expiry as i use below code
Note: i believe NIFTY 50 and NIFTY asset same while fetching delta value
delta_values = tsl.get_option_greek(strike=25200, expiry=0, asset=‘NIFTY’, interest_rate=10, flag=‘delta’, scrip_type=‘CE’)
@Tradehull_Imran Sir
i am getting error while calling the historical data, timeframe “DAY”.it is workable for few securities but not giving the output for every stocks.
Hello @Tradehull_Imran Sir,
While Installing Library I am getting these error:
ERROR: Could not find a version that satisfies the requirement pandas-ta (from versions: none)
ERROR: No matching distribution found for pandas-ta
Kindly help me out with this problem, so I can proceed further.
Thank you in advance.
for getting option greeks, we can now use option chain provided by API directly. This makes the data accurate, and much faster to access
use this code
atm, option_chain = tsl.get_option_chain(Underlying="NIFTY", exchange="INDEX", expiry=0, num_strikes=20)
Also update the codebase as well
pip install Dhan-Tradehull

Hi @KLchawla
See if the wrong names does not have a spacebar added to it,
Like this is right, "MOTHERSON"
But this is wrong " MOTHERSON"
and this is wrong "MOTHERSON "
Also share your code as well
send your python version,
on cmd write and send screenshot
python --version
Also you can proceed ahead, this is a minor issue we can skip it for now, and solve when it comes later.
Sir, I somehow solved it. Thank you very much sir.
From your archives, kindly remove Logging installation from library, it caused issue with me.
I am using the Python 3.8.0 as you shared in the sesson 2 latest file.

Hi @Faisal_E ,
The code seems to be working fine, check the symbol name that has been passed via the code:

Do we have the Open Interest indicator implemented in tsl library?
If yes, can you please provide the code to map the open interest values for options chart.
