Yep thanks, that sums it up, I think I was reading into why it is called a test, not only what it is as a bar, but also what it's doing, because it's a test of supply and sort of questioned why not the reverse test of demand, but you've clarified that's not called a test, it's a small upthrust. Would you consider a small upthrust a test of demand and if successful next bar down?
Sorry if this sounds odd, I really appreciate the effort you take to help,
cheers
