How can orders be executed at 7pm when the LSE is closed?

Hello IE team,

Just saw the following sentence in your system:

Orders are executed in our daily trading window between 2 pm and 7 pm. Actual amounts may differ slightly from those shown below.

I understand that the LSE closes at 4:30 pm, so I don’t get how orders cloud be executed at 7 pm?

I would appreciate if you could clarify this!
