If you are trading, just watch SZ to SZ, Example: 574 VA High long to SZ 630, pass next SZ up (675), reject back to VA High, no hold then may try 480, hold at 480 then back to 574, pass at 574 then may try 675 or 725. This example may actually play out as typed, I would not doubt it (may be by EOD Monday regular session).
