Nifty50 probable movement on 18.12.25

 



1. Derivatives Positioning Snapshot (as of 17-12-25)


Futures positioning (Index)

FII futures OI: –164,650 (shorts increasing)

DII futures OI: +45,256 (consistent long accumulation)

PRO futures OI: +11,994 (mild supportive longs)

Cumulative futures OI: –107,400 (net bearish structure intact)

Daily futures OI change: –3,858 → shorts being held, not meaningfully covered



👉 Inference:

This remains a FII-short vs DII-long standoff, with FIIs firmly controlling directional bia


Options positioning

FII option OI net: –332,283

PRO option OI net: –244,991

Cumulative option OI: –577,274

Daily option OI change: –42,463



👉 Inference:

Heavy net option selling, dominated by call writing

No evidence of panic short covering


Indicates range-capping + downside pressure 

Cash market

FII cash: +₹1,171 Cr (buying)

DII cash: +₹768 Cr



👉 Important nuance:

Cash buying has not translated into futures covering, suggesting:


Arbitrage / stock-specific buying

Derivative desk still structurally bearish


2. Chart-Based Technical Read (Attached Image)



Trend & Averages


Price below VWAP

Trading below EMA 55 / 100

EMA structure flattening → early distribution phase

Momentum

MACD: Deep in negative territory, histogram expanding → downside momentum intact

RSI (14): ~46 → below neutral, no bullish divergence

Volume Profile

High supply zone: 25,950 – 26,050

Repeated rejection near VWAP confirms sell-on-rise behavior


3. Multi-Day Data Structure (Why downside bias persists)


From 08 Dec → 17 Dec:

FII futures shorts expanded from –138k → –165k

Cumulative option OI stayed deeply negative throughout

Every pullback rally saw call OI rebuilding, not unwinding

👉 This confirms a positional bearish structure, not a short-term reaction.


4. Market Sentiment for Tomorrow


Overall Bias

Bearish to Range-Bound with Negative Skew

Rallies are likely to be sold into, not chased.


5. Key Levels for Tomorrow (Derived from OI + Chart)


Resistance (Sell Zones)


25,900 – 25,950 → VWAP + call writer supply

26,000 – 26,050 → strong OI + volume resistance

❗ Any move above this zone without FII short covering is suspect



Support (Watch Carefully)

25,780 – 25,750 → intraday support

25,700 → critical breakdown level

Below 25,700, expect momentum acceleration


6. Probable Scenarios


Scenario 1 (High Probability – 60%)

Flat to mildly positive open

Rally towards 25,900–25,950

Fresh call writing + futures shorts reassert

Close near lows

Scenario 2 (Bearish Expansion – 25%)

Break below 25,750

Stops trigger → fast move to 25,650–25,600

Scenario 3 (Low Probability – 15%)

Sustained move above 26,050

Requires visible FII futures short covering

Until then, this is not the base case


7. Institutional Reading (Desk Conclusion)


FIIs: Directionally bearish, controlling index via derivatives

DIIs: Absorbing supply but not strong enough to reverse trend

PROs: Tactical longs only, not trend-changing


Options market: Acting as a ceiling, not a launchpad


Final View


Sell on rise remains the dominant strategy.

Until FII futures shorts reduce meaningfully, upside will stay capped and fragile.”
