What Is Arbitrage? Profiting from Price Differences Across Markets
What Is Arbitrage?
Arbitrage is a trading strategy that involves buying an asset at a lower price in one market and selling it at a higher price in another, aiming to profit from price differences.
It relies on market inefficiencies rather than price direction.
Why Arbitrage Exists
Arbitrage exists because:
- Markets are fragmented
- Prices update at different speeds
- Liquidity varies across platforms
- Supply and demand differ
Arbitrage helps align prices across markets.
How Arbitrage Works
- Price difference is identified
- Asset is bought in cheaper market
- Asset is transferred or swapped
- Asset is sold in higher-priced market
- Profit remains after fees
Speed and execution are critical.
