At least one complete impulse wave up from low of 4462.25, with evolving impulse wave off low of 4482.25. I would say the key price level to stay above (in the short term) would be 4482.25; if so, I would expect higher highs back towards 4600 for the rest of the week.
An impulsive move below 4482.25 opens up a move below 4462.25 and beyond.
