SPY gap exists from $107.62-$110.34. Intraday high yesterday was $106.11. The cash index unclosed gap from October 6th exists at 1097.56 - 1099.23. Thats about a 3% move for the cash index to get there which is a bit more percentage-wise than SPY.
Indexes worldwide making new highs (except Shanghai which retraced up only 50% so far) and euphoria is breaking out. Expect high total volume today.
