Lot Calculator EA
for MetaTrader 4^®

The Idea Behind the Expert Advisor

The EA focuses on collecting tool functions for working with orders. Moreover, it submits them in a convenient and informative way. It will help you save an enormous amount of time and raise your skills to a higher level!

The head tool function is a lot calculation due to a specified risk size (USD/Lot/% of the balance). Also, it provides detailed information about the future lot.

The EA adds three horizontal lines to the chart. Their values can be changed both through the main Lot Calculator window and by moving them on the chart:

• Yellow — the pending orders placement price.
• Red — the Stop Loss price.
• Green — the Take Profit price.

The tool can be used on any timeframe of any currency pair.

The Expert Advisor's interface consists of two windows:

• The main one.
• The opened orders list window with interface element set for controlling them.

Let us consider the tool interface and its capacities in more detail!

The Lot Calculator Main Window 

There are three buttons at the top of the Lot Calculator main window:

• Order List — opens the additional window with an order list and functions for controlling them. This window deserves special attention, and we will return to this later.
• Reset — resets all the main window settings. 
• Send Order — the button for order placing.

The main window of the tool is divided into three blocks. Each one has its thematic set of elements for analyzing and calculating a future order. Let us examine each of them:

1. Order parameters

The Order Parameters Block

This block contains the Use pending order checkbox, allowing switching between instant and pending market orders. Also, it has three input fields, such as:

• Entry price — the order placing price that works with pending orders only. The Use Pending Order option must be enabled. Otherwise, the order is placed at the Bid/Ask price.
• Take Profit — the price at which a profitable trade is closed.
• Stop Loss — the price at which a losing trade is closed.

2. Lot parameters

The block sets risks that determine the actual lot size.

Lot Parameters Block

• Risk type — the dropdown list for switching the risk type. There are three possible options:
  • USD — the lot will be calculated according to the specified number of currency units. This value is set in the Risk size input field.
  • Lot — the actual lot size. The value is set in the Risk size input field.
  • % of the balance — the lot will be calculated according to the specified percentage of the balance. The value is set in the Risk size input field.
• Risk size — an input field for calculating the lot due to the risk size. The type of value (currency/number/percentage) depends on the selected risk type in the Risk type parameter.

3. Risk info

A block collects useful information about a future order in a tabular form. It is calculated due to the previously specified parameters in the instrument's first two blocks.

Risk Info Block

Let us take a closer look at each row of the table:

• Risk Reward — the ratio that allows comparing the expected return with the maximum risk to obtain these returns. To calculate this ratio, divide the amount of profit expected after the position is closed by the amount that could be lost if the price moves in the opposite direction.
• Lot Size — the calculated actual lot size.
• Risk Amount — the amount in a currency unit that can be lost if the trade is losing.
• Risk Of Balance — a percentage of the current balance that will be lost if the trade is losing.

Open Orders window

As we have clarified earlier, the Open Orders window can be opened by clicking on the Order List button in the main window.

This window provides convenient access to all open orders. Its flexible functionality allows closing filtered orders if necessary.

Open Orders Window

Open Orders Window (horizontal scrolling)

The Open Orders window is divided into two main sections:

• The first one is a set of functional elements for creating a filter for order closing.
• The second one is a table with orders and all possible information about them.

Let us consider them in more detail.

The first section has two buttons:

• Close all orders — close all open orders and delete all pending orders of the current currency pair. It interacts with the Close-only EA's orders parameter (description is below).
• Close orders — close filtered orders only. It interacts with the parameters: Close only EA's orders, profit less/more than * value *, Close BUY, and Close SELL (description is below).

Elements for filtering closed orders:

• with profit [less than/more than] * value * — set the comparison and the value of the profitability/loss ratio of closed orders.
• Close only EA’s orders — if checked, it closes orders opened by this EA only.
• Close BUY — closes buy orders (LONG) if checked, or ignores them if unchecked.
• Close SELL — closes sell orders (SHORT) if checked, or ignores them if not checked.

Table columns and their meaning:

• CloseButton — button to close an order. By clicking, it instantly closes the current order.
• Ticket — the order ticket number.
• Type — the order type (Buy/Sell/BuyStop/SellStop/BuyLimit/SellLimit).
• Symbol — the currency pair of the current order.
• OrderProfit — the profit/loss in case of immediate order closing.
• ClosePrice — the price of immediate order closing.
• OpenPrice — the order opening price.
• Lots — the number of order lots.
• StopLoss — the value of the order closing price when the loss is reached.
• TakeProfit — the value of the order closing price when the profitability level is reached.
• Swap — the swap value of the currently selected order.
• OpenTime — the order opening time.

Input Parameters

There is only one option in the incoming parameters — Magic Number. It separates orders placed by this EA from orders placed by other EAs. This value also acts as an additional filter when you delete orders in the Open Orders window if the Close only EA orders parameter is enabled.
