Yep, the Swing Account won't let me open more than 2lots.
I had a 1lot on US30, then tried to open a second 1lot, but got the "not enough money" message.
Managed to open a 0.5lot.
I had been banking on going mad with lotsize in last 2 days.
I have sent FTMO a message to just clarify this.
Pretty sure I could open 4 - 5 lots on the normal account.
