No hb&b, you've got it wrong. Everyone has tried to help you understand, but you're unwilling to learn. Think of it like this if it helps:
"The UK Markets opening had the following effect".
Indeed, which is why you should say "Let's see what effect the UK Markets opening has." You are seeing what the result of opening the UK Markets is.
If you're going to try and patronise dazzer, it would help if you weren't wrong.
Are you really a journalist?
