Types of Arbitrage

Arbitrage is a trading strategy where traders exploit price differences for the same or similar financial instruments across different markets or forms. The Indian share market, with its complex dynamics and multiple exchanges, offers several arbitrage opportunities for traders and investors.

What is Arbitrage?

Arbitrage involves buying a security in one market and simultaneously selling it in another to profit from price differences. It ensures market efficiency by minimizing price discrepancies.
