Feature to subscribe to multiple expiries

[pramakrishn]

The existing functionality allows users to subscribe to a single expiry when utilizing the option chain feature. The capability to subscribe to multiple expiry dates concurrently is missing. This will broaden the versatility of the option chain and significantly benefit users managing diverse portfolios.

while subscribing users should be able to provide input like

data = {
'23-07-2023': ['NFO:BANKNIFTY', 'NFO:NIFTY'],
'25-08-2023': ['NFO:HDFCBANK', 'NFO:BANKNIFTY', 'NFO:NIFTY']
}

Code describing the advanced usage: how to save the file in csv
stream = OptionStream(symbols, secrets,
expiry='23-02-2023',
criteria=criteria,
redis_config=RedisConfig(db=1)
)
stream.start() after starting the stream. Can you please help me.

@Gil3232
After starting the stream, you can use this code to create a csv
I have added few columns, based on your requirement you can modify it

option_chain_fetcher = OptionChainFetcher()

option_chain = option_chain_fetcher.get_option_chain('NFO:BANKNIFTY')
import csv


filename = 'banknifty.csv'

# Write to the CSV file
with open(filename, 'w', newline='') as f:
    writer = csv.writer(f)

    headers = [
        'exchange', 'symbol', 'strike_price', 'ce_premium',
        'ce_bid_price', 'ce_ask_price', 'pe_premium',
        'pe_bid_price', 'pe_ask_price'
    ]
    writer.writerow(headers)

    expiry = option_chain['expiry']
    for expiry_date, options in expiry.items():
        for option in options:
            row = dict.fromkeys(headers, '')
            row['exchange'] = option_chain['exchange']
            row['symbol'] = option_chain['trading_symbol']
            row['strike_price'] = option['strike_price']

            for ce_pe in ('ce', 'pe'):
                if ce_pe in option:
                    row[f'{ce_pe}_premium'] = option[ce_pe]['premium']
                    row[f'{ce_pe}_bid_price'] = option[ce_pe]['bid_price']
                    row[f'{ce_pe}_ask_price'] = option[ce_pe]['ask_price']

            writer.writerow(row.values())

Thank you so much.

hi can this be done with proper gui, i am sure you have one, for some one who wants to focus on trading rather than coding, i have script for nsepython lib, which works but not reliable as data from nse is not fetched easily on every call

[hbinmadi]

my plan is to hire some one to develop me a reliable gui, which gives me real time change in io in near atm + 1000 -1000 of bank nifty option and change in price
eg: pcr/ money in near ATM options,

Hi,
How to fetch all FNO derivatives as per the symbol mention in an excel sheet? Suppose I had mentioned a cell name in excel as: Symbol
Reliance
then Reliance derivative data will fetch and show the CE/Pe max oi, LTPm Chng LTP, Volume, Ch in Oi, Max Oi strikes CE/PE
then if i type TATAPOWER then their derivative data as above will show.

Hi @sujeetk789, this project supports retrieving the data through APIs. If you have knowledge of programming, you can use the above snippet of code to write the data to an excel sheet.

@hbinmadi I am not certain about the date.
