Price is approaching the lower Bollinger Band, which is widening, suggesting downside continuation.

In summary, it would appear that further selling is in the cards for the SPX on all three timeframes, with their respective support levels noted above. I'd also refer you to my post of April 10th, which describes 1250 as a potential downside Fibonacci confluence support target.
