Share trading operations involve buying and selling shares of publicly listed companies on stock exchanges. Here's a breakdown of the process:

*Key Participants:*

- *Stock Exchanges*: Platforms like Pakistan Stock Exchange (PSX), Bombay Stock Exchange (BSE), and National Stock Exchange (NSE) facilitate trading.

- *Stockbrokers/Brokerages*: Intermediaries that execute buy and sell orders for investors.

- *Investors/Traders*: Individuals or institutions that buy and sell shares.

- *Regulatory Bodies*: Securities and Exchange Commission of Pakistan (SECP) or Securities Exchange Board of India (SEBI) oversee trading activities.

*Trading Process:*

- *Order Placement*: Investors place buy or sell orders through their brokers.

- *Matching Orders*: The stock exchange matches buy and sell orders based on price and time priority.

- *Trade Execution*: Trades are executed, and details are confirmed to the broker and investor.

- *Settlement Cycle*: Trades are settled within a specified timeframe (e.g., T+2 days).

*Order Types:*

- *Limit Order*: An order to buy or sell at a specified price.

- *Enhanced Limit Order (ELO)*: A limit order that allows matching of up to 10 price queues.

- *Special Limit Order (SLO)*: An order that allows matching at multiple price levels without storing the order in the system.
