# Market Impact: A Systematic Study of the High Frequency Options Market

## TL;DR

This study investigates the market impact of large options orders in Asian markets, revealing that their behavior aligns with known equity market impact laws such as the square-root law and fair pricing condition.

## Contribution

It introduces an algorithmic method to identify metaorders in options markets using implied volatility parameters, extending impact analysis to options.

## Key findings

- Market impact follows the square-root law.
- Market impact dynamics are similar to equity markets.
- Identifies metaorders using implied volatility parameters.

## Abstract

This paper deals with a fundamental subject that has seldom been addressed in recent years, that of market impact in the options market. Our analysis is based on a proprietary database of metaorders-large orders that are split into smaller pieces before being sent to the market on one of the main Asian markets. In line with our previous work on the equity market [Said et al., 2018], we propose an algorithmic approach to identify metaorders, based on some implied volatility parameters, the at the money forward volatility and at the money forward skew. In both cases, we obtain results similar to the now well understood equity market: Square-root law, Fair Pricing Condition and Market Impact Dynamics.
