What You Can See Here Without Logging In?

The Options Buildup loads with NIFTY 50 by default. Without logging in, you can view:

  • The full Chain View with Buildup tag, Volume, OI, and LTP for both CE and PE across every strike.
  • Contract View and Chart View for the same data.
  • The most recent expiry for the selected instrument.

All data reflects a 15-minute delay. NIFTY 50 loads by default. SENSEX and Nifty Bank are only one tap away, present as quick tabs. Through search, you can switch to other indices, F&O stocks, and commodities, but with the same 15-minute delayed data.

You need to log in to add strikes to a basket, execute trades, and access future expiries beyond the nearest one.

Reading the Chain Above: A Worked Example

The default view displays the NIFTY 50 for the most recent expiry. The layout is structured as Call options (CE) on the left, Put options (PE) on the right, and the Strike Price in the centre. The At-The-Money (ATM) strike is highlighted for easy reference.

The Buildup Tag: Long Buildup, Short Buildup, Long Unwinding, Short Covering

Each strike has a tag next to the standard metrics that shows the current buildup status. This tag is based on the relationship between price movement and OI changes, giving you a quick visual indication if a particular strike is being aggressively bought, sold or if it is being liquidated.

  • Long Buildup: Price rising, OI rising. It indicates fresh long positions entering.
  • Short Buildup: Price falling, OI rising. It indicates fresh short positions being added.
  • Long Unwinding: Price falling, OI falling. It indicates long positions being closed.
  • Short Covering: Price rising, OI falling. It indicates short positions being closed.

Volume, OI and LTP Per Strike

Each row shows LTP, OI, and Volume for the CE and PE at each strike.

  • LTP (Last Traded Price): Shows the latest traded price for that contract.
  • OI (Open Interest): Shows the total number of active, open contracts.
  • Volume: Shows how many contracts traded during the session.

These three columns are read alongside the Buildup tag, not in isolation. A Buildup signal carries significantly more weight when backed by high volume and high OI.

Chain View vs Contract View vs Chart View

The Options Buildup offers three distinct ways to view the same buildup data:

  • Chain View: The classic table layout, suitable for comparing CE and PE at specific strike prices.
  • Contract View: A linear table that concentrates on the single contract details, not the dual-sided view.
  • Chart View: A graphical representation of the buildup data over time, which helps you identify trends and momentum changes.

How to Read Options Buildup Signals?

Buildup is most useful when you analyse the pattern behind the tag, not just the tag itself. Here's how:

Long Buildup: Rising Price, Rising OI

When both prices and Open Interest increase simultaneously, it suggests fresh long positions are entering the market. It is often interpreted as a bullish market signal, as traders are willing to pay higher prices and open interest is also rising.

Short Buildup: Falling Price, Rising OI

It typically indicates fresh short positions are entering. It is interpreted as a bearish signal as price is declining while open interest is increasing.

Short Covering: Rising Price, Falling OI

Short Covering is when the price rises and open interest declines. It implies that the shorts are exiting positions, which decreases the total OI. This can lead to sudden and steep price surges.

Long Unwinding: Falling Price, Falling OI

A decline in both prices and Open Interest indicates that the long buyers are closing their positions (selling to close), which may be because of profit-booking or capitulation. Selling pressure pushes prices down while total active contracts decline.

Reading Buildup Across Strikes, Not Just One

A single strike showing Long Buildup is a data point. Four consecutive CE strikes showing Long Buildup while the market is rising is a pattern. Traders analyse the data as a ladder, not as isolated rows. Contract View and Chart View are useful follow-up steps once a cluster is identified in Chain View.

What is Options Buildup?

Options Buildup classifies the positioning activity at each strike by combining OI change with price direction. It tells you more than OI change. OI change alone tells you whether contracts were opened or closed, but it does not indicate whether buyers or writers drove the activity.

Buildup pairs OI change with price direction to infer which side is likely responsible. For example, rising OI with rising price signals that buyers are driving the activity.

How is the Buildup Tag Calculated?

The Buildup tag is calculated using two inputs: Price direction and OI change into the following four outcomes:

  • Price ↑ + OI ↑ = Long Buildup
  • Price ↓ + OI ↑ = Short Buildup
  • Price ↑ + OI ↓ = Short Covering
  • Price ↓ + OI ↓ = Long Unwinding

The tag is recalculated as new data arrives. It is a classification based on observable inputs, not a confirmation of positioning intent.

How to Use the Chain Controls?

The controls are built to make the Options Buildup tool useful even before login, while still reserving some advanced features for logged-in users.

Searching Indices, F&O Stocks & Commodities

Before logging in, NIFTY 50 loads by default with 15-minute-delayed data, but you can search and switch to other indices, F&O stocks, and commodities.

Selecting Expiry

The nearest expiry loads by default without login. After logging in, future expiries are available. Changing expiry redraws the entire data for that date.

Switching Between Chain View, Contract View and Chart View

The toggle buttons on the top of the data table allow you to change formats to Chain View, Contract View and Chart View. This enables you to switch between broad strike scanning, specific contract analysis, and time-based trend analysis. The three formats are accessible without logging in.

What Unlocks After Login?

After logging in with your Options Trader account, you can remove the 15-minute delay and have full execution capabilities like:

The Buildup Tag in Real Time

Once logged in, Buildup tags, OI, Volume, and LTP values are updated in real time. The Options Buildup is not a snapshot of prices but a live positioning map that updates as price and OI change during the session.

Selecting Multiple Strikes Into a Strategy

Checkboxes appear next to each CE and PE row. Ticking a box adds that contract as a leg in your strategy panel, with Buy/Sell, lot size, and live price. Additionally, you gain access to Live Overall Margin, Final Margin, Hedge Benefit, and Net Premium.

Watchlist, Basket and Execute All

Once your legs are selected in the strategy panel, you have three execution paths: save the setup to a watchlist for later tracking, push it to a basket to queue it alongside other trades, or click Execute All to route every leg to the exchange simultaneously with no re-entry of strike data required.

Key Terms to Know

Buildup Basics

  • Open Interest (OI): The total number of active, unsettled contracts currently held by market participants.
  • OI Change: Difference in OI from the reference point. Positive = contracts added; negative = positions closed.
  • Volume: The number of contracts traded.
  • Buildup tag: 4 different tags are provided depending on the combination of O.I. Change and price direction.

The Four Buildup Types

  • Long Buildup: It has rising price + Rising OI, representing fresh long positioning entering.
  • Short Buildup: It has falling price + Rising OI, representing fresh short positioning entering.
  • Short Covering: It has a rising price + Falling OI, representing existing shorts closing, driving price up.
  • Long Unwinding: It has a falling price + Falling OI, representing existing longs exiting and pulling price down.

  • The chain view displays tags across every strike in the ladder simultaneously, so the complete positioning picture is visible in a single view.
  • It also offers chart view, contract view and multi-strike OI as companion tools.
  • After logging in, the transition from identifying a Buildup signal to adding the contract to a basket requires only selecting the checkbox.

Things to Know Before You Trade Options

Buildup is an interpretation of positioning activity based on price and OI data. It should not be treated as a confirmed signal. Tags can change rapidly within the same session depending on the market conditions.

A cluster of strikes showing the same tag is more informative than a single row. Therefore, before taking a position, traders should verify the Buildup reading alongside price action and other tools.

Frequently Asked Questions

Both have rising prices. Long Buildup has rising OI (new longs entering); Short Covering has falling OI (existing shorts exiting).
