POST-IB BRIEF — NIFTY

  • Open (23195) landed almost on yesterday’s value low (23200) — the low-conviction base case; the 22-pt gap filled by 09:15.
  • Initial Balance (first hour) rallied hard, 23194 to 23325 (132 pts, ~70% of 20-day avg range) — wide enough to likely hold the day, unbroken so far.
  • Day is developing a P-Shape: swift rally on a thin base — short-covering signature, not confirmed new buying.
  • Anchored VWAPs stack bearish (today’s anchor below yesterday’s, below the day before), even as price sits just above its own anchor.
  • TRAP WARNING: the rally runs into a naked point of control 15 pts above today’s IB high.

OPEN ASSESSMENT
Open Auction at 23195, on yesterday’s value low — sentiment unchanged overnight, matching last night’s base case. Gap filled within 15 minutes.

INITIAL BALANCE
23194-23325 (132 pts, ~70% of the 20-day average range) — wide enough to likely hold today’s extremes, narrower than yesterday’s 165-point balance. No breakout yet; price (23296) sits 29 pts under the IB high.

VOLUME & OPTIONS CHECK
Straddle decayed a modest 7% since the open, short of the 15-20% collapse confirming a balance day. Implied vol is down ~6% from yesterday’s close despite an 85th-percentile reading (a two-session move), as realized vol accelerates. Put wall: 23200 (today’s IB low); call wall: 24000.

DEVELOPING DAY TYPE
A developing P-Shape — an excited early push stalling into balance near the highs, short-covering rather than fresh buying — against a bearish multi-week backdrop (VWAPs stacked down, trend measures bearish too). Day-timeframe activity drives this; nothing confirms genuine OTF buyers.

TODAY’S PLAN
– LINE IN THE SAND: 23325 (today’s IB high).
– Above: trust continuation toward 23448-23593 only if accepted (2+ prints) through the naked POC at 23340 first. TRAP WARNING: short-covering into resistance is a fade, not a breakout to chase.
– Below: favor a fade to the prior POC (23220) and the IB-low/value-low/put-wall floor (23193-23200). A break reopens yesterday’s buying-tail low at 23116.

KEY LEVELS
Level | Type | Why it matters
23593 | Gap Top | Unfilled gap ceiling
23448 | Selling Tail | Overhead rejection
23340 | Naked POC | Untested magnet
23325 | IB High | Line in the sand
23220 | POC | Fair-value pivot
23193 | IB Low/VAL/Put Wall | Confluent floor
23116 | Balance Low | Buying-tail low
