Different types of orders will have different execution parameters. Day orders, for example, will not be fulfilled if they cannot be completed on the same day they are placed. GTC orders, on the other hand, can be executed at any time until the trader cancels the order.

Brokers can carry out orders in a variety of ways. They can send a request to an exchange's floor, complete the trade with a market maker, or complete the trade digitally. Alternatively, if the broker already has the means to execute the trade in its own inventory, it can do so.

Executing different types of orders in stocks involves using various order types to manage trading strategies effectively:

1. Market Orders: Buy or sell stocks immediately at the best available price. Quick execution is the priority.

2. Limit Orders: Buy or sell at a specific price or better. Execution occurs only if the price meets the specified limit.

3. Stop Orders: Trigger a market order once the stock reaches a specified price, useful for limiting losses or securing profits.

4. Stop-Limit Orders: Combines stop and limit orders; triggers a limit order when the stop price is reached.

5. Trailing Stop Orders: Adjust the stop price at a fixed percentage or dollar amount below the market price, protecting gains while limiting losses.
