NF had a mild short covering day on Thu.Buyers expected next to get gap/drive to stay above P profile in next session else probe back to 17660/17620 expected. They got open above PDH but failed to sustain and got move down closer to 17640.Later session pushed higher above PDH to rally to close above dVAH with spike. Neutral extreme up day with spike. Spike rule applies for next session. 17855-17925 spike zone..Sustain in/above spike zone for further move higher else test back VWAP/POC zone possible. Buyers considered out of woods with a move above 17825 which they did now. But advance/decline and spike not closing at higher quad suggests lesser odds for quick follow through above this spike and might get retest down to check with buyers. Hence suggested to avoid carrying longs. Any pullback next session they should defend 17855 or worst case 17780-17810 zone and look for push higher above PDH else Friday spike buyers could be cleared with a liquidation move. More bullishness now if this spike gets follow through above 17950. Levels wise, 17855 support for next session and buyers should hold it and go for higher value towards 17950/17990-18010/18050/18100. Failing to do so could drop to 17810-17780 if sustains 17740/17700/17650 test possibl. Swing wise same 17950 still good resistance. Not clearing this early in the week looking for retest of 17780/17700-17650 and decide there.Focus now is balance between 17650-17950 zone and the way they clear this zone could lead to next idea whether trend or more balance.
