I think Buy signal is almost confirmed. Patient bulls may buy when prices soften.
[1392.00 - 1397.20] zone is the confluence of very short, short and medium term rising trend lines that a healthy bullish market wants to respect.
[1386 - 1389] zone is where bulls may be at risk if it is not hold.
If today the SPX closes in red, we may expect a big bounce after three consecutive days in red in the bullish market.
All that means if [1392.00 - 1397.20] is respected at close and the index is in red at close, it would be a big chance to buy for one or two rebound next days.
