I have the same problem on IB using a cash account. I converted CHF to USD this morning but when I try to buy VT for less than the amount of USD showing in my portfolio I get the message:
“YOUR ORDER IS NOT ACCEPTED. THERE IS INSUFFICIENT SETTLED CASH [-XXX USD for XXX] IN YOUR ACCOUNT TO OBTAIN THE DESIRED POSITION.”
I guess I indeed have to wait a while for the cash to settle before I can use it to buy other securities.
Is there a way to know how much cash has already settled?
@Cortana I’m surprised you don’t have this problem.
