Request to build Customizable Trending OI with PCR in DEXT

Hi @Bhavya_Jain

Request to Implement Trending OI in DEXT

Overview

Request to introduce a Trending OI (Open Interest) feature in DEXT to help traders quickly identify significant changes in Open Interest and understand market positioning.

1. Trending OI

The feature should identify contracts experiencing significant changes in OI:

  • OI Increase – Significant addition in Open Interest

  • OI Decrease – Significant reduction in Open Interest

  • Long Build-up – Price ↑ + OI ↑

  • Short Build-up – Price ↓ + OI ↑

  • Long Unwinding – Price ↓ + OI ↓

  • Short Covering – Price ↑ + OI ↓

2. Strike Selection

Users should be able to control which strikes are included in Trending OI.

Options should include:

  • Specific strike selection

  • Manual multiple-strike selection

  • Custom strike range

  • CE only

  • PE only

  • CE + PE

  • Expiry selection

Trending OI should be calculated only from the strikes selected by the user.

3. PCR Value

The Trending OI section should also display Put-Call Ratio (PCR).

PCR should be available for:

PCR value should be implemented

The PCR should be calculated based on the user-selected expiry and strike range, rather than automatically using the entire option chain.

For example:

ATM ± 10 strikes → Calculate Put OI / Call OI only from those selected strikes.

This makes the PCR more relevant to the user’s selected trading range.

4. PCR Trend

DEXT should also show how PCR is changing over time:

  • Current PCR

  • Previous PCR

  • PCR Change

  • PCR Change %

  • PCR trend

For example:

PCR: 1.18 ↑ +0.12

This can help users identify whether Put OI or Call OI is increasing relative to the other.

6. Time-Based Analysis

Allow users to select time frame

7. Filters

Users should be able to filter by:

  • Index

  • Futures

  • Options

  • CE / PE

  • Expiry

  • Strike

Objective

The objective is to create a customizable Trending OI scanner where users can select the expiry, strike range, CE/PE and time period and immediately see:

  • Where OI is increasing or decreasing

  • Long Build-up

  • Short Build-up

  • Long Unwinding

  • Short Covering

  • PCR

  • PCR change/trend

This would make Trending OI a powerful tool for option-chain analysis, intraday trading and identifying changes in market positioning and sentiment.

Thanks for sharing this in detail.

We’re already working on similar lines around OI-based Movers and analysis, including identifying areas such as OI Gainers/Losers, Long Build-up, Short Build-up, Long Unwinding and Short Covering, along with expiry and related filters.

We’re also working on complementary OI views to help analyse how OI and PCR are changing over time.

Please have a look once these improvements are available. If you still feel there’s something specific missing around, do come back to us with the use case — we’d be happy to evaluate it.
