Just cause it's near today's low and the 10 day EMA. A pure guess really in fact! The 10 day EMA has been really useful lately, acting like a magnet and a springboard. Stick one on a 10 min (405EMA I think, if yr chart is 2.30-9.15) and you'll see what I mean.
We have bounced off the 61.8% of the most recent 5 wave up in a wave B. C projects to 1153 pivot roughly as long as 1159 holds on a retest.
I wouldn't rule out another test of 1159 though.
Looking at bigger waves we may be near the start of a big C down in which case we could go as low as 1146.5 (equal in length to the big selloff). If that happens we break a major channel and all hell could break loose! But the 10 EMA usually does a good job of catching falls.
Don't listen to me though, I came close to losing 1k this morning.
