The most deliberate guardrails on the platform

Expiry-day options move differently — this workspace is designed around that, not despite it.

Live settlement countdown

A running hours:minutes:seconds countdown to 15:25 IST — the exact exchange settlement time — always visible.

At-the-money defaults

The chain opens on ATM strikes by default, where the swings this workspace exists for are sharpest — other strikes are still one tap away.

Enforced session loss limit

Set your maximum acceptable loss once — new buy orders are genuinely blocked platform-wide once it's hit, not just flagged.

Type-to-confirm override

Continuing past your loss limit requires typing a full confirmation word — never a single accidental tap.

Mandatory risk acknowledgment

A short, specific explanation of expiry-hour options behavior, with an active confirmation required before your first session.

Liquidity warnings on thin strikes

Strikes with thin trading activity are flagged directly — the last-traded price may not be what you'd actually get filled at.

How it works

From opening the workspace to placing your first trade.

1

Complete the risk acknowledgment

A one-time confirmation on first use, before the workspace opens.

2

Set your session loss limit

The maximum you're comfortable losing today — enforced, not just advisory.

3

Trade the ATM chain

Opens on at-the-money strikes by default, with liquidity warnings where relevant.

4

Watch the countdown, manage into settlement

The live clock to 15:25 IST keeps you oriented as the window narrows.

What-if analysis

See what the premium does before you commit

Pick a strike, set a move in points, and the What-if panel projects the premium about an hour ahead — down, flat and up — with next hour's decay applied.

Navia Expiry Trader option chain with the What-if analysis panel projecting premium for a 50-point move down, flat and up, with next hour's decay applied

Three scenario cards — down 50 pts, flat, up 50 pts — show the projected premium and change, alongside PCR, Max Pain, Call/Put OI and ATM IV. Navia states the assumption openly: IV is held constant, so read these as directional estimates, not quotes.

Why the guardrails are stricter here

Expiry-day options carry well-documented, elevated risk. This workspace is built to give you more information and more control before a trade goes in — not to promise a particular outcome.

An enforced limit, not a suggestion

The session loss limit genuinely blocks new buy orders once hit — closing or reducing existing positions is always still allowed.

Acknowledgment before access

You confirm you understand expiry-hour risk once, before your first session — not buried in terms you never see.

Liquidity called out, not assumed

Thin strikes are flagged directly, so a quoted price is never mistaken for a guaranteed fill.

Frequently asked questions

Everything you need to know about the Expiry Trader Workspace.

What time does the settlement countdown count down to?

15:25 IST, the exchange's expiry settlement time — shown live in hours, minutes and seconds so you always know exactly how much time is left.

Why does the chain default to at-the-money strikes?

ATM strikes see the sharpest price swings in the final hours before expiry, which is exactly the window this workspace is built for — you can still browse other strikes anytime.

What happens once my session loss limit is hit?

New buy orders are blocked platform-wide. Continuing past the limit requires typing a full confirmation word, not a single tap. Closing or reducing existing positions is always still allowed.

What is the risk acknowledgment I have to complete?

A short, specific explanation of why options behave differently in the last hour before expiry, with an active confirmation required before your first session in this workspace.

What do the liquidity warnings on some strikes mean?

They flag strikes where the last-traded price may not reflect what you'd actually get filled at, due to thin trading activity — a common risk on far strikes close to expiry.
