What Happens to Options on Expiry Day?

Let me show you something I shared with my students. Look at the chart above. Nifty opened near 23,150, sold off about 270 points and closed near 22,873. The 23150 and 23100 call options, which traded at ₹140 to ₹150 in the opening spike, ended at ₹0.05.

That is a 100% loss for every buyer who held. Many traders said, “So never buy OTM, just sell it.” But one day is not a rule. Had Nifty rallied 300 points instead, those same calls would have exploded and sellers would have been in deep trouble.

Expiry day is Intraday Trading (1 din ka trade) in its purest form. Retail traders love it because premiums are cheap. That is exactly why they struggle: cheap options are cheap for a reason.

The Wide Weekly CPR Trap Zone: Where This Trade Happened

This is the most important part of the chart. Look at the indicator panel on the Nifty chart. The current weekly CPR width is 1.25% and the monthly width is 2.12%. Both are marked Wide. When the weekly CPR is this wide and price trades inside it, I call it a Trap Zone.

A wide range lets price swing both ways without a real trend. Breakouts fail and premiums keep leaking. A buyer who bought the 23150 CE on the opening spike was buying inside the trap, not at a clean breakout.

Nifty then failed to hold the daily CPR, slid through the zone and settled near the weekly CPR floor around 22,860. Sellers had the edge, but only those with defined risk survived the opening spike.

My rule is simple. Inside a wide weekly CPR, I do not buy OTM. I either stay out or use a defined-risk spread. I take a directional option only after price closes outside the zone with an Elephant Candle.

Why OTM Options Die So Fast

An out-of-the-money option has no intrinsic value. Its whole price is time value, which falls to zero at the closing bell if the strike is not reached. If you buy a 23150 CE at ₹40, Nifty must go above 23,190 just to break even at expiry.

The Boom and the Trap

Now the other side. Expiry days sometimes give a sudden Boom, a sharp one-sided move that turns a ₹5 option into ₹60 in minutes. People post the “zero to hero” wins and never the 20 times it failed. I teach my students to treat the Boom as a bonus, never as the plan.

Option Buyer vs Option Seller on Expiry Day

The Option Buyer has limited risk and unlimited reward, but a low win rate. The buyer needs direction and speed together.

The Option Seller has a high win rate, but the reward is capped and the risk is large. One strong trend day can erase many small wins. In the chart above, a seller who entered during the first spike faced a big adverse move before the decay started.

My view after 9+ years: do not be a naked seller or a lottery buyer. Be a planned trader with defined risk.

Using the CPR Indicator as a Leading Indicator

The CPR indicator is a Leading Indicator. Top Central (TC), Pivot (P) and Bottom Central (BC) come from the previous day’s data, so you know the levels before the market opens.

On expiry day I check width first. Narrow CPR (below about 0.15% of price) hints at a trending day that favours the option buyer. Wide CPR (above about 0.5%) hints at a range-bound day that favours defined-risk selling. A virgin CPR, which price has not touched, adds weight to the level.

The same chart shows why width matters. The weekly CPR was Wide, so I treated the day as a trap, not a trend.

My Step-by-Step Expiry Day Workflow

Step 1: Pre-market (before 9:15)

Check the Gift Nifty chart for the gap direction. Mark yesterday’s high and low, the daily CPR and the weekly CPR, and note whether each is narrow or wide.

Step 2: Skip the Opening Trade chaos

The first 5 to 15 minutes are the Opening Trade zone, where premiums swing wildly. I wait and watch for an Elephant Candle, a big-bodied candle that breaks a CPR level with strong volume. If price is still inside a wide weekly CPR, I skip the breakout.

Step 3: Entry with confirmation

I enter only after a 5-minute candle closes above TC (long) or below BC (short), using an ATM or slightly ITM option, never far OTM.

Step 4: Stop-loss and Reward to Risk Ratio

Decide the exit before you click buy. Example per unit; multiply by lot size.

I never risk more than 1% to 2% of capital on one trade. On ₹2,00,000, that is ₹2,000 to ₹4,000. If one lot’s stop-loss exceeds that, I skip the trade. I skip any trade below 1:2 Reward to Risk Ratio.

Step 5: If you sell, hedge it

On a wide-CPR day I prefer a credit spread. Sell the 23150 CE at ₹40 and buy the 23250 CE at ₹12. Your credit is ₹28 and your maximum loss is capped at ₹72 per unit. The reward is smaller, but a runaway trend cannot destroy you.

Wide CPR vs Narrow CPR on Expiry Day

Common Mistakes and Fixes

Mistake 1: Buying far OTM “because it is cheap.” A ₹3 option is cheap because its chance is tiny. Fix: stay near ATM.

Mistake 2: Chasing the first candle. Fix: wait for a confirmed close beyond a CPR level.

Mistake 3: Selling naked without a hedge. Fix: always use spreads or a hard stop.

Mistake 4: Overtrading. Expiry is exciting, and excitement kills discipline. Fix: set a maximum of two trades and a daily loss limit.

Frequently Asked Questions

Is it good to buy options on expiry day?

It can work if you buy ATM or slightly ITM options after a confirmed breakout with a fixed stop-loss. Far OTM buying is a low-probability bet because time decay is at its highest.

Is option selling on expiry day profitable?

It has a high win rate, but one trend day can wipe out many wins. Defined-risk spreads, sizing and a stop-loss make it safer.

What does virgin CPR mean?

A virgin CPR is a Central Pivot Range that price has not touched during the day. Traders treat it as a likely support or resistance zone next session.

How do I use a CPR calculator for expiry day?

Enter the previous day’s high, low and close. Pivot = (H+L+C)/3, BC = (H+L)/2 and TC = (Pivot − BC) + Pivot. Mark them before the open and check whether the range is narrow or wide.

Which is better on expiry day, option buyer or seller?

Neither wins every time. Buyers do better on narrow CPR trend days, and defined-risk sellers on wide CPR range days. Choose by structure, not emotion.
