Trading signals

On the previous page (Indicators) we added all indicators. Once all indicators are added, you can create the trading signals ('signals') you want to use for the opening or closing of an order. If you want to edit your indicators, you simply go back and adjust your parameters.

Signals are a very powerful tool to create almost any Open- and Close logic you can think of. Creating a signal may seem quite difficult in the beginning, but we believe that anyone can master building signals within a week. So let's be persistent and learn how to create signals.

You can use the “And” operator when all conditions need to be true, or the “Or” operator when any of the conditions need to be true. You can compare indicators, set up conditions or compare constant values. So far, we've been able to create almost any strategy we could imagine. If you run into a limitation of the tool, please let us know and use the contact form , or mail us on .

Building signals

Your EA always has 4 signals.

• Open Buy
• Open Sell
• Close Buy
• Close Sell

You can activate or deactivate a signal by clicking on the options button and select activate/deactivate. The EA needs at least an active Open Buy or Open Sell signal to work correctly. When you disable both of the Open signals, your EA will never open an order.

You can use the same menu as used for activating/ deactivating a signal to Copy and Paste a signal to the other types of signal. A common scenario is that you start by creating the Open Buy Signal. When ready, you may want to copy the Open Buy signal to the Close Sell signal and you may want to copy the Open Sell signal to the Close Buy signal. This way the open order will switch from a buy order, to a sell order and vice versa.

You can use the same menu as used for activating/ deactivating a signal to invert a signal. A common scenario is that you start by creating the Open Buy Signal. When ready, you will want to create the Open Sell signal, which is the same as the Open Buy signal, but then Inverted. To do so, click the Inverse button on the Open Sell signal after you copied the signal from the Open Buy signal.

You can click the signal you want to edit, which will open the signal editor.

An indicator always has a Shift and a Shift+1.

• Shift: The shift value as defined in your indicator.
• Shift+1: The shift value as defined in your indicator + 1.

A signal has 1 root node. The root node cannot be removed. Start building your condition from the root node.

You can remove nodes by starting at the leaves of the signal and select "Remove" under options. A leaf is a node without children. If a node has leaves the node cannot be removed.

Rearranging the nodes is possible by using drag-and-drop. Hover over the signal, press the left mouse button, drag the node and drop it where you would like it to be.

When you are building signals you can create a signal that is invalid. Invalid signals cannot be saved. You know that your signal is invalid when you see the exclamation mark with an error message in the top summary box.

You can make signals as complex as you would like. To easily understand how signals work, a good strategy is to divide them into blocks. Each block returns true or false.

Signals can be nested. This allows you to build even more complex signals.

Options context menu

Click on the button after the node. This will open the option menu. Depending on the node you clicked this will give you several options.

This option will add a condition. A condition is an expression with a left operand, an operator and a right operand. By default, the left and right operands are indicators. The indicators you've created will appear here. You can toggle between an indicator, function or constant by clicking on the arrow next to the indicator.

• Click on Indicator to access the indicators you have created.
• Click on Function to access functions like ask, bid, hour, minute etc.
• Click on Value to add a constant value. The default value is EMPTY which represents a MetaTrader empty value: 2147483647.

This option will add a part of a condition. You can toggle between indicator, function and constant.

Adds an operator. Must be used as a parent node and therefore must contain child nodes. If there is an operator without child nodes it will be ignored. For a full list of operators go to Operators. Use the arrow next to the operator to toggle between operator categories. You may or may not see all categories when you toggle through the available options. This depends on the kind of parent operator.

This removes a condition, condition part or operator. Only end-nodes can be removed. Start by removing the end-nodes first.

Operators

The signal editor enables you with a set of well known operators. We've added a set of special crossover operators to make things easier.

Symbol	Name	Category
	Crossover	Crossover
	Crossover from below	Crossover
	Crossover from above	Crossover
And	And	Logical
Or	Or	Logical
==	Equal to	Comparison
!=	Not equal to	Comparison
>	Greater than	Comparison
<	Less than	Comparison
+	Add	Arithmetic
-	Substract	Arithmetic
/	Divide	Arithmetic
*	Multiply	Arithmetic
%	Modulo	Arithmetic

Use this operator if the direction of the crossover does not matter.

Use this operator if the direction crosses over from below.

Use this operator if the direction crosses over from above.

Logical AND operator. Apply this operator to multiple boolean expressions. Returns true if all expressions are true.

Logical OR operator. Apply this operator to multiple boolean expressions. Returns true if one or more expressions are true.

Comparison operator. Returns true if both sides of the expression are equal.

Comparison operator. Returns true if both sides of the expression are not equal.

Comparison operator. Returns true if the left side of the expression is greater than the right side of the expression.

Comparison operator. Returns true if the left side of the expression is less than the right side of the expression.

Use this operator to add numbers.

Use this operator to substract numbers.

Use this operator to divide numbers.

Use this operator to multiply numbers.

Returns the remainder after a division.
