The magic number for me would be SPX 2560/61 today in the first hour of trading. IF that does not happen, then a slightly different scenario would be in play than previously thought (a high and low in the same day). The previous (x) wave ran 2 TD's (Oct 5-9) so IF today is wave (y), then (z) could run 2 TD's also, which points to a Wednesday low.
Wave (x) ran from 2552 down to 2541. Normally, wave (z's) are c's: hard waves down. An xyz scenario right here going down into Wed would imply higher prices directly ahead. IF we do the previously thought of scenario (hi/lo) in same day, the resulting scenario would imply a choppy move move to new highs by the end of next week.
GDX could move a little higher on open today, but my thinking suggests a pull back today followed by a big move up on Wednesday.
