this swing from around low of 840. if spx still range bounce around this level, say below 975, in next 2 or 3 hours. Then long need looking for opportunity to exit. If spx keeps this small day range (less than 15 points) so far till close, then a distribution day will be labeled. Short entry is advised by the close today or early tomorrow. if friday's low is taken out late today, i would not hesitate to exit the long(i am flat now) at market price but a lot profit vapourated though. Anything above 990 will invalid above assessment. so adjust your position accordingly. in between 975 and 990 is a grey area. one has to weight the probability toward either side. but it'll be clear by close.
