Highest CE and PE open interest walls

Option Writer Activity Scanner

Q: What is option writer activity?

It is the positioning of traders who sell options, measured through open interest. The strikes with the most call and put open interest, and how that open interest is changing, show where writers are concentrated and whether they are adding or leaving.

Q: What is the highest call OI strike?

It is the call strike with the largest open interest for a stock and expiry. It is widely read as a resistance level because call writers gain while price stays below it. The highest put OI strike is read the same way as support.

Q: What does writer unwinding mean?

Unwinding means open interest at a wall is falling because writers are closing positions. The scanner shows it as a negative OI change percentage at the call or put wall.

Q: What do Explosive, Strong, Moderate and Developing mean?

They tier a breakout by writer unwinding at the crossed wall: more than 10% is Explosive, 5% to 10% is Strong, under 5% is Moderate, and Developing means price crossed the wall but writers are not unwinding yet.

Q: What are PCR@CE and Tilt in the table?

PCR at a wall compares put open interest with call open interest at that wall's strike. Tilt expresses the same comparison as a share of the strike's total open interest: positive means puts dominate, negative means calls dominate.

Q: How often is the option writer scanner updated?

The data refreshes every five minutes during market hours for the selected expiry. A historical date can be chosen to review an earlier session.

Q: Is an active trigger a trading signal?

No. Active triggers is a filter for stocks that have crossed a wall with writers unwinding, or sit within about 2% of one. It does not predict price, so check the chart, volume and liquidity yourself.

How to read option triggers · filters, columns and thresholds

How This Tool Works (Simple Explanation)

Think of option writers as big players creating pressure zones. Highest Call OI often behaves like a ceiling and highest Put OI often behaves like a floor. When price breaks these zones and writers start unwinding, momentum can expand quickly.This page helps you quickly find those symbols instead of checking every option chain manually.

Step-by-Step: How to Filter Opportunities

Step 1: Select Expiry DateStart with the nearest relevant expiry so signals reflect current market positioning.

Step 2: Pick Market SideUse sentiment and breakout filters: Bullish for stocks above a call wall, Bearish for stocks below a put wall, Neutral for stocks between the walls.

Step 3: Keep Stronger ParticipationApply minimum OI and unwinding level filters so weak names are removed and only meaningful activity remains.

Step 4: Turn On Active Triggers OnlyThis keeps stocks where price already crossed a key wall with unwinding, or is within roughly 2% of the wall with unwinding in progress.

Step 5: Sort the ResultsSort by Signal Strength, Gap %, or OI Change % to bring the strongest positioning to the top. A trigger is more meaningful when price action also agrees.

All Controls You Can UseSearch by symbol, choose one or many sectors, switch sentiment (bullish/bearish/neutral), choose breakout status, set minimum OI, filter unwinding level (low/moderate/high), enable Active Triggers Only, sort by any major metric, and use pagination for larger lists.

Trigger Desk: Full Column Explanation

Top Strip: Trigger Desk | Symbols | Sorted by | TimeThis tells you how many symbols are currently visible after filters, which column the table is sorted by, and last refresh time. Use this first to confirm you are seeing fresh data.

CE PCR/TILTPCR@CE compares Put OI vs Call OI at the CE wall strike. Tilt@CE shows which side is heavier at that strike. Negative tilt means CE side is dominant.

PE PCR/TILTPCR@PE compares Put OI vs paired Call OI at the PE wall strike. Tilt@PE shows whether Put side or paired Call side is stronger there.

CE Desk / PE DeskShows strike, OI, and Chg %. In this table, negative change usually means writers are unwinding; positive means fresh build-up.

Call Side / Put SideGap % tells distance from wall in percent, Dist in points, and wall text tells location: Above, Below, or At CE/PE wall.

Symbol & Signal BlockContains symbol name, live price, sector tag, breakout badge, bias chip, signal score (0-100), progress bar, and TradingView quick-link icon.Breakout badges mean stage of move: Explosive strongest unwinding, Strong high unwinding, Moderate mild unwinding, Developing price crossed wall but writers are not unwinding strongly yet.Near +x% means distance to nearest wall. Smaller value means price is closer to a trigger zone.

Quick Reading Sequence (10-second scan)1) See breakout badge and bias. 2) Check CE/PE Chg % for unwinding direction. 3) Check Near % and Gap %. 4) Keep only names with liquidity and clear price confirmation.

Exact Numeric Thresholds Used in This ToolBreakout stage (Bullish): Price above CE strike. CE OI change % < -10 = Explosive, < -5 = Strong, < 0 = Moderate, otherwise Developing.Breakout stage (Bearish): Price below PE strike. PE OI change % < -10 = Explosive, < -5 = Strong, < 0 = Moderate, otherwise Developing.Unwinding filter: uses the larger of the CE and PE open interest that left the wall (a build counts as zero). High = >= 10%, Moderate = >= 5% and < 10%, Low = < 5%.Active Trigger logic: Bullish breakout if price > CE strike and CE OI change < 0. Bullish near trigger if price is between 98% and 100% of CE strike and CE OI change < 0. Bearish breakout if price < PE strike and PE OI change < 0. Bearish near trigger if price is between 100% and 102% of PE strike and PE OI change < 0.Signal score (0-100): Neutral base is 50. For bullish/bearish breakout rows, score = 50 + (2 x the % of OI that left the wall), capped at 100. Writers adding at the wall do not raise it.

Reading Checklist

Bullish Read

Breakout status bullish or near bullish trigger
CE Chg OI % negative (call unwinding present)
Adequate OI and good liquidity
Price and volume agree with the read

Bearish Read

Breakout status bearish or near bearish trigger
PE Chg OI % negative (put unwinding present)
Adequate OI and good liquidity
Price and volume agree with the read

Re-check every refresh cycle. If unwinding and breakout conditions fade, the read is weaker.

The option writer activity guide explains the highest call and put OI strikes, writer unwinding and how the Explosive, Strong, Moderate and Developing tiers are set.

What the Option Writer Activity Scanner shows

For every NSE F&O stock the scanner finds the highest call OI strike and the highest put OI strike for the chosen expiry, shows how open interest at each wall is changing, and measures how far price sits from it. A falling wall means writers are unwinding; a stock beyond a wall with writers leaving is tiered Explosive, Strong or Moderate.

Filter by sector, sentiment, minimum open interest and unwinding level, combine two expiries, or open a historical date to review an earlier session. It describes positioning and does not give trade recommendations.
