Plus you can buy and sell currencies at spot rate. So if you want to buy something in another country, e.g. Canada, Mexico, you can save your self a lot of spread (2-5%) on 100Ks. Then you can wire from there.IBKR isn’t as good with cash as Fidelity but they currently pay 4.8% if greater than $10k (IBKR pro). 3.8% for IBKR lite. Need to sign up for the program.

IB Sweep is also good but us currently closed to new high net worth customers. Perhaps they will reopen it someday.
