The API only has live data and so does not contain historical contracts. The web file download is for historical. The web download should be self-contained - i.e. query what...

Thanks - appreciate it - and also UM futures symbols please

Thanks for that. How will these be kept up to date? So what happens just after a contract has expired?

There are items missing from cm-futures-symbols.txt. For instance searching for "_211231" returns 5 contracts. https://data.binance.vision/?prefix=data/futures/cm/daily/klines/ has 9 contracts for _211231

Are the various symbols.txt files manually populated? (Hopefully not!) They could be populated by a query that looks at data.binance.vision and runs on a schedule (e.g. daily)

some 2206 and 2209 contracts are also missing from cm-futures-symbols.txt. I think there are other contracts missing for other months.

ok - I can see all the contracts for BTCUSD and ETHUSD now

Correction: there is an error message: "- ^FTSE: No data found for this date range, symbol may be delisted"
