Error in fetching expiry list

The expiry_list('NIFTY') function doesn't work anymore. It just gets stuck. Is it because of issues in NSE website or with the library? Please help.

Few days back I was able to fetch data using nsepython but I am unable to fetch data now for some reason. Can someone let me know if the library is working fine on their end?

Even after using the commit b0b7d36 was not able to resolve the issue

Have raised PR for tackling below issue 70accbf

The main use case is to iterate over all nse_eq symbols

symbols = nse_eq_symbols()
for symbol in symbols[:3]:
    print("This is my symbol :: ",symbol)
    df = nse_eq(symbol)
    print("Price info :: ",df['priceInfo'])
    open_val,high,low,current = df['priceInfo']['open'],df['priceInfo']['intraDayHighLow']['max'],df['priceInfo']['intraDayHighLow']['min'],df['priceInfo']['lastPrice']

Connection not working in Ubuntu Digital Ocean VPS

I am running NSEPython from Ubuntu VPS in Digital Ocean. I am running the function to fetch expiry date of the contracts. But it isn't loading anything. But from my local Windows desktop it is working. Is there any special configuration I should do to run in Ubuntu? But through Firefox in Ubuntu, I am able to access the nseindia.com API URL. Kindly help. Thanks.

401 error when we fetch nse data

I am trying to get the last closed price of a stock. And the nsefetch() gets a 401 error response. And when we try to get json from it we get a requests.exceptions.JSONDecodeError

Details/Steps to recreate
I am running everything for a local setup. And for my code I am using this.

from nsepython import *
symbol = 'SWSOLAR'
print(nse_eq(symbol)['priceInfo']['close'])

And it errors out here when we try make the get call to https://www.nseindia.com/api/quote-equity?symbol=SWSOLAR. It returns a 401 and when we try to jsoninfy it we get the error raised up requests.exceptions.JSONDecodeError: Expecting value: line 1 column 1 (char 0).
This is the details of the 401 response that we get.

Future warning of frame append while using oi_chain_builder()

Hi,
I am using oi_chain_builder(), But getting following warning.

rahu.py:146: FutureWarning: The frame.append method is deprecated and will be removed from pandas in a future version. Use pandas.concat instead.

I tried to modify line no. 146 of rahu.py: oi_data = oi_data.append(oi_row, ignore_index=True) as oi_data = pd.concat([oi_data,oi_row],index=False), but not succeed.

Could anyone please guide me to get rid of this error.

index_history not working

index_history doesn't seem to work, even using the recent updated version of rahu.py of @buzzvolt
https://github.com/buzzvolt/nsepython/blob/master/nsepython/rahu.py

OI Chain Builder returns data only for the current expiry

oi_chain_builder is supposed to return the data for any expiry date based on the date but it does not return the same. If we pass any date as an argument it returns a blank dataframe.

Suggestion to rename the default "latest" argument to "current". Equity has only 3 concurrent expiry dates. Hence names suggested "current", "next" and "last"

For Indices there are options for 21 expiry dates running concurrently at a given time. So giving a list of date options or allowing an integer input for no of weeks to expiry can make usage easy.

nsepython prints lot of unnecessary debug information

In local usage of nsepython, it logs all request responses, without giving a way to control this logging.
I understand this may be helpful in debugging nsepython itself, but a client app should have a way to control its library logs.
This causes unpleasant spamming in client logs and makes client logic harder to debug.

NSE Lot Sizes function throws error

File .venv/lib/python3.12/site-packages/nsepython/rahu.py", line 484, in nse_get_fno_lot_sizes (code, name) = [x.strip() for x in line.split(',')[1:3]] ^^^^^^^^^^^^ ValueError: not enough values to unpack (expected 2, got 1)

Seems like the problem is in the url:
url="https://archives.nseindia.com/content/fo/fo_mktlots.csv"

Throws 404. Perhaps need a new URL?

Documentation link doesn't seem to work

I have just downloaded nsepython and wanted to give it try. But it seems that the documentation link https://unofficed.com/nse-python/documentation/ isn't working

Upgrade for nse_events()

Can we have a filter for the time range for nse_events, for example, If we want to have a custom filter based on filters present on the website it would be great .
Example: https://www.nseindia.com/companies-listing/corporate-filings-event-calendar

Thanks & regards,

is_market_open bug

function is_market_open return true even if is holiday today.
Problem is in the line:

nsepython/nsepython/rahu.py

Line 909 in 6f3a728

return True

This only checks for first holiday from the nse_holidays() json result and return True by checking only the first. It should be continue here to check for the next holiday date and a final return true at the end of function.

Unable to get derivative history.
The sample program in documentation also does not work.
