The futures have made it very unlikely that Thursday and Friday's action constituted a fourth wave; I have therefore labeled the chart thusly:
This count calls for a Minute [c] down to ~1125-1135. This move may in fact be a Minor 3 which could go lower (in which case relabel Minute [a], [b] as Minor 1, 2 and move the subwaves up a degree). In purple is some idle speculation on how the next move might unfold. If we do gap down tomorrow setting up a small wave 5, wave 2 will ideally need to be deep to ensure both the gap on the index proper and the gap on the futures are filled. (The gap on the futures could be filled later tonight, though.)
As we are approaching 30-minute oversold status, I wouldn't be surprised to see a relief rally that would constitute our wave 2, then turn hard down. This would go along with the gap fill.
The best bullish count is that this is a leading diagonal, but calling it that seems like a forced count. LDs are 5-3-5-3-5, and the move up in June is too blatantly a "three". Still, if it is a bullish LD, I would expect either the red trendline or the 1309 low (wave 2 of 1 in this case) to provide support.
1422.38 very well could be the top for years; it is only 2 SPX points away from the Fibonacci 88.6% logarithmic retracement value (1424.55) of the entire 1570-666 move. This bull is getting long in the tooth, and time may already have run out.
