My experience is not the same. Those that do not offer a laundry list on the website provide a service that needs to be customized to each client and can't be represented in the way you want.
We only offer US Listed Equities, Options and Futures. I expect we will add Fixed income before foreign.
Read the Big Short to see how badly people with $30m and an ISDA were treated. You need $130m to get an ISDA today.
