Could you please clarify what you meant by “what is made by”? Is it something along the lines of “what is the benefit to Freetrade?”
Basic trades are aggregated into large transactions and executed at the end of the day, at 16:00. You could cancel them up to 15:45. Proof.
If you have an S&S ISA with Vanguard, most likely you will not be able to contribute towards Freetrade’s ISA when it is launched (unless the regulations change). Your options would either be to liquidate your Vanguard ISA and stick to Freetrade’s or remain with Vanguard and use Freetrade’s general investment account.
The interbank market is the top-level foreign exchange market where banks exchange different currencies. The banks can either deal with one another directly or through electronic brokering platforms. It is mainly used for trading among bankers hence the exchange rate is pretty much the best you can get in the world. I might be wrong (@Rob would be the best person to clarify), but even Freetrade does not get that rate hence the 0.5% on the top is the cover for the charges Freetrade pays to their banking provider.
Just a snazzy word for “storage”
