Eurex data source is tough to find.

For historical options data…Eurex links you to the German Bourse which in turn links you to a "Canari.dev." But their pricing catalog only shows all options available as single package, without any selection to limit it to just a few equities or underlyings, and not even sure if futures options in there. Because it's the entire history (I put in 2012 till now which seems standard time frame for US) it's pricing it at 38,000 Euros (!). I've emailed the Bourse three times asking about individual equities data, but no response.

We've used Polygon and Algoseek, and I looked at the Nasdaq market, and CBOE, but none of them has historic Eurex options data.

Anybody know where available, particularly OESX (not the US OESX symbol/company) which is similar to our SPX, with a volume of as much as a million contracts daily?
