How to add feed after the feed.run()

[Vowenchu]

Hi,

I am a new dev. I am currently stream option data from bybit. There are new symbols everyday as new option contracts created.
I can run the script now but want to add new symbol in the add_feed everyday. How should this be done in cryptofeed?

you'd need to set something up to read the symbol data at whatever time/cadence you desire, and then create a new feed. There is an example that does this:

You'd just need to make the appropriate calls to get the new symbol data from the exchange (https://github.com/bmoscon/cryptofeed/blob/master/cryptofeed/exchange.py#L78 make sure you set refresh to True when you make this call) and then use whatever new symbols to make new subscriptions.
