In automated trading systems (EAs), there are typically six types of order operations, categorized as follows:
Type 0 = Buy
Type 1 = Sell
Type 2 = Buy Limit
Type 3 = Sell Limit
Type 4 = Buy Stop
Type 5 = Sell Stop
Out of these, four are classified as pending orders. Let's examine each type:
Buy Limit
A buy limit order is set below the current market price. It is designed to open a buy position when the price falls to the specified level. Key considerations for a buy limit order include the order type and the distance from the current price to the desired entry price.
Sell Limit
A sell limit order is set above the current market price. It is designed to open a sell position when the price rises to the specified level. Similar to the buy limit order, the essential elements are the order type and the distance from the current price.
Buy Stop
A buy stop order is set above the current market price. It is designed to open a buy position when the price rises to and breaks through the specified level. It's important to observe and compare the characteristics of this order type with the others.
Sell Stop
A sell stop order is set below the current market price. It is designed to open a sell position when the price falls to and breaks through the specified level. Careful observation and comparison with the other order types are recommended.
Implementing Pending Orders in EAs
To effectively utilize all four pending order types within an EA, it's beneficial to have a function that calculates the correct order type based on specified parameters. This can simplify the EA's logic.
Example Usage (Conceptual):
For a buy limit order:

For a sell limit order:

For buy stop and sell stop orders, similar logic would apply.
Further EA Development
The goal is to create EAs that are easy to understand and implement. By carefully observing the mechanics of each order type and employing helper functions, developers can build more sophisticated trading robots.
