Quote from ammo:
sometimes when you pull up a daily or weekl monthly you get 3 or 4 nips close together,going in the middle sometimes filters those out, heres the 1 yr with prior lows for res and the nip top is 47 we are coming into exp so the 3 month is the more recent open positions ,hypothetically,the more recent , the higher likelihood there are still remaining longs who would be glad to break even and provide needed sellers to stop a move up,now it's a coin flip as to the 47 on the yearly acting as res or the 57 ,top of cleave as res,since any spot in the cleavage is considered a touch,another guesstimate on the cleavage and nips acting as supp/res along with the fact that they are the most and least traded spots,could be that if you went and looked at a large sample of the top 50 of the 500 spx stocks, they would possibly be at previous supp/res when spu's hit these areas.
