Friday, September 18, 2026 — A Marginal New High, Rejected Again, and a Round-Trip Back to Flat

NIFTY futures opened at 23,379.0 on Friday and, within the first hour, ticked to 23,420.0 — a marginal new high, just above Thursday's 23,418.0 rejection point. It got turned back there again, drifted down through the middle of the session to 23,312.6, and spent the rest of the day working its way back, closing at 23,378.5 — up 45.1 points (+0.19%), almost exactly where it opened.

A full round trip, in both directions, that ended up going nowhere net. After Thursday's real trend day, today was the market taking a breath.

Order Flow Analysis

The marginal new high, rejected again

The session's early push to 23,420.0 tested the same overhead zone that turned back Thursday's rally, and it held again — a 0.67 order-flow print at the high marked a real, if smaller, rejection. This is now the second straight session the market has tried this level and failed to clear it with any conviction.

A choppy middle, then a recovery

From the rejected high, price drifted down to the low of the day (23,312.6), with the OI-behaviour read alternating between Long Unwinding and Short Covering through the whole session — both sides trimming, nobody committing. White buying prints near the low marked the floor, and the session spent the afternoon working back up to close near the open.

A magenta band capping the middle of the range

A Prominent POC band sat right around 23,353 for most of the day — solid resistance-turned-pivot territory that the session spent hours grinding against before finally clearing it into the close.

15-minute footprint. Marginal new high 23,420 rejected (0.67 print), drift to 23,312.6, recovery back to 23,378.5. OI-behaviour churned Long Unwinding / Short Covering all session — no fresh conviction either way.

Key Order Flow Takeaway

  • The overhead zone held for a second straight session — today's 23,420 tag was turned back the same way Thursday's 23,418 was.
  • A genuine round-trip day — 108 points of range, net change of just 45 points, essentially closing where it opened.
  • OI churned all session, no fresh conviction — Long Unwinding and Short Covering alternating, both sides trimming, nobody adding.
  • The 23,561–23,563 level remains completely untested — today's high, like Thursday's, stayed well short of it.

Market Profile Analysis

Today's value area — VAL 23,320 / POC ~23,364 / VAH 23,386, about 66 points wide — is narrower than Thursday's ~97-point range, consistent with a more contained, two-sided session rather than a directional one.

NIFTY market profile, September 18, 2026

30-minute TPO. Friday's value 23,320 / 23,364 / 23,386 — narrower than Thursday's, reflecting today's contained, round-trip character.

Structural Levels

For Monday, from today's H/L/C (23,420.0 / 23,312.6 / 23,378.5): an ultra-narrow ~8-point daily CPR (BC 23,366 / PP 23,370 / TC 23,374) — the tightest of the run, sitting almost exactly on today's close. A third straight session handing off a genuine trend-day signal.

Resistance

  • 23,399 / 23,408 — Monday's Camarilla H3/H4.
  • 23,420 — this week's twice-rejected high.
  • 23,428 — Monday's R1.

Support

  • 23,359 / 23,349 — Monday's Camarilla L3/L4.
  • 23,321 — Monday's S1.
  • 23,312.6 — today's low; below that, thin to Monday's S2 at 23,263.

Options and Futures OI

  • PCR (OI): 0.99 at the open → 1.13 by the close — put writers gained real ground through the day.
  • Call OI fell ~3% (166.0L → 160.8L); Put OI rose ~10% (164.9L → 181.2L) — a genuine, if modest, shift toward put writing.
  • Max pain moved from 23,300 to 23,350, tracking price up through the session.
  • Futures OI essentially flat (17.67M → 17.67M) — no net conviction from futures.

A mild put-writing lean into the close, but nothing dramatic — consistent with a session that round-tripped rather than trended.

Trading Implications

The stall case. Two straight sessions rejected at the same overhead zone, a contained round-trip day, no fresh futures conviction — this reads like a market that's found a ceiling just short of the real 23,561–23,563 level and needs more time or a fresh catalyst to actually test it.

The coiling case. An 8-point CPR is about as tight as this run has produced. Coiling this tight after two tests of the same resistance often resolves with real force, one direction or the other — Monday's first hour matters more than usual for reading which way.

The level that decides it. Nothing changes the framework's read until either 23,420 clears with real follow-through, or 23,312 breaks and holds. Everything in between is the market digesting the week's two rejections.

Conclusion

A quiet week-closer after Thursday's real trend day — a marginal new high rejected at the same level for the second straight session, a full round trip through the middle, and a close that landed almost exactly back at the open. Nothing was resolved today; the overhead zone held again, the OI data showed nobody pressing either side, and Monday inherits the tightest CPR of the entire run. The week ends with the real question — whether 23,561–23,563 ever gets a genuine test — still completely open.
