NF had dPOC skew with advantage buyers at close in last session. Buyers expected to accept above 18045 early in session to get 18120 then later 18160. They gone for this quick at open to get till 18140.Failed to get acceptance higher above 18045 expected move back to 17965-17945 which happened via open test drive down and probed only till 17969. Both happened quick in IB period then all day skewed higher to IBH again to close there. It was almost a normal day today auctioning in morning IB range..Looking for imbalance session next out of this profile. Poor high at top. Close had dPOC skew higher again and got advantage for buyers..They need to defend 18100 and drive higher to 18175 and above or better get gap and accept above 18175 for 18210/18240 if sustains more bullish. Failing to sustain higher and moves below 18100 means could rotate down in todays value area and then test tail zone at low 17990 if sustains more weakness towards yday tail zone 17945. As said yday, still having balance to continue bias and intra auction is confirming the same..Not expecting rally yet..To negate this view, they need to build value above 18175 and once done should not come below 18100..If happens solid liquidation possible back in last two days range. Swing short negation at 18175 and obj remains open at 17650.
