__TOC__
Signal is a mechanical technical analysis tool, used to systematically specify market entry or exit points according to a set of trading rules implemented in the signal's algorithm. The trade points are indicated on a chart by ticks and arrows.
Basic adjustments to the signal’s logic can be made by simply changing the '''Input Values'''. Signal's Arrow, Tick, and Label '''Style''' can be set.
== Setting Input Values ==
An '''Input''' is a constant used in the signal’s signal's calculations. Signals can have one or more inputs, or none at all. Each input is assigned a name. There are three types of inputs: Numeric,
True/False, and String.
Signals can be modified by changing the input '''Values'''.
Most, but not all, signals use input values; to learn more see [[<span style="color: red;">'''LINK'''</span> /03_PLE/31-0103_WorkingStudies.html name="5"; Default_Study_Properties|Default Studies Inputs]].
One of the main advantages of using the inputs is that basic adjustments to the study's logic can be made be simply changing the input values, without the need to edit the studies' actual code.
# In the '''Value''' column, click on the value of the input that you want to change and enter the desired value.
<div style="background-color: #E5F6FF;">Tip: To use these inputs settings as the default for the selected signal, check '''Use as Default''' check box.</div>

== Setting Style ==
# In the '''Size''' column select the component size from the drop-down list box; only the size of arrows and ticks can be set.

== Intra-Bar Order Generation ==
You can elect select whether to allow the signal to generate orders within a bar, or only at the close of each bar.
A signal contains one or more Order Commands that generate entry or exit orders. A limit to the number of orders that can be generated within a single bar by each order command or by all of the signal’s order commands can be set.
# Open the '''Format Signal''' window.<br><span>{{FormatSignal}}</span>
# Select the '''Intra-Bar Order GenerationProperties''' tab.
# Check '''Enable Intra-Bar Order Generation''' check box to allow the signal to generate orders within a bar; uncheck the box to allow the signal to generate orders only at the close of each bar.
If this option is grayed out then the Intra-Bar Order Generation condition is specified in the signal's code. The strategy can send different amount of orders depending on the selected IOG mode: # Select the required modefor entries:#* To limit each order command entries from the same signal in this strategy to once per bar, click '''Limit entries from the same signal in this strategy to once per bar''' radio button.#* To limit entries from all signals in this strategy to one entry and one exit once per bar, click '''Limit each order command entries from all signals in this strategy to once per bar''' radio button. #* To allow the signal multiple entries per bar, click '''Allow any entry from this strategy to one entry and one exit occur ... times per bar''' radio buttonand specify the value from 1 to 10 000. # Select the required mode for exits:#* To limit exits from the same signal in this strategy to only one entry once per bar, click '''Limit exits from the same signal in total and only one exit this strategy to once per bar''' radio button.#* To limit exits from all signals in total this strategy to once per bar, click '''Limit exits from all signals in this signal strategy to one entry and one exit once per bar''' radio button. #* To allow the signal multiple entries and exits per bar, click '''Allow unlimited entries and any exits from this strategy to occur multiple times per bar''' radio button. <br><div style="background-color: #E5F6FF;">Tip: To use these settings as default for the selected signal, check '''Use as Default''' check box.</div>
<div style="background-color: #E3FBE5;">Note: Allowing multiple same-direction entry orders in the '''Position Limits''' section of '''Strategy Properties''' window will not override the above settings.</div>
