I’ve never used a broker that displays more than one price and those were large european banks. Is that a thing?
Imho it’s more confusing for beginners to see two prices. That would lead to countless people asking questions about it on here or quitting immediately. Partly because live prices are not offered, both prices will likely be very incorrect leading to even more confusion.
So I agree with Freetrade that one price is much better for UI and usability for beginners.
