A Trading Unit represents the standard quantity of shares, bonds, or other securities that is generally accepted for trading purposes on the exchanges. It defines the minimal number of financial instruments that can be bought or sold in a single transaction.

Standardization
The concept of a trading unit ensures standardization across financial markets, which helps in maintaining liquidity and efficiency. By setting a minimum or standard quantity for trading, exchanges facilitate smoother and more predictable buying and selling of securities.
Round Lot vs. Odd Lot
Trading units are often categorized into two main types:
- Round Lot: A standard trading unit, typically 100 shares for most stocks.
- Odd Lot: Any quantity of shares less than the standard round lot, often resulting in higher transaction fees or less favorable prices due to the odd lot nature.

- Stocks: A round lot is usually 100 shares.
- Bonds: A trading unit can be $1,000 face value of bonds.
- Options: Typically, one contract represents 100 shares of the underlying stock.
