TradeStation EasyLanguage Programming Requirements Definition – Before you start a TradeStation EasyLanguage programming project, requirements might be submitted in writing via email. A programmer may contact you with a lot more questions or clarifications regarding the requirements, when necessary. You will then obtain a Strategy Specification Document.

EasyLanguage is really a proprietary programming language which was created by tradestation developer and that are part of its electronic trading platform.

Even though the TradeStation trading package comes with a multitude of trading indicators known as analysis techniques, many who use TradeStation develop the need to incorporate or customize their own indicators using TradeStation code. This article will demonstrate how to make a simple indicator that displays the existing trading volume and in addition changes the visual indication of this volume to green when price closes up.
The most basic method to create a new indicator is to locate a preexisting indicator that partially addresses certain requirements and then modify it further. With this example, the Volume indicator that comes with TradeStation gives an acceptable foundation.
To start dealing with TradeStation code, first open the amount indicator with the EasyLanguage editor. EasyLanguage will be the programming language that TradeStation uses. Start by right-simply clicking any chart, then select Insert Analysis Technique from the pop-up menu. From the dialog box that appears, choose the Indicator tab, and after that scroll down to get the Volume indicator in the list. Click once on the Volume indicator row to highlight it, and after that click the Edit EasyLanguage button below the list box. The EasyLanguage editor will open using the code for that Volume indicator ready for editing.
EasyLanguage code is split into three sections. The first block defines the Inputs. These inputs can only be changed by formatting a warning sign after it has been included in a TradeStation chart. After the Inputs would be the Variables. These initialize when the indicator first launches during a session, and their values are modified using code. After both of these blocks is definitely the actual code that executes. This is just what needs modified for your example.
First discover the following line of code: Plot1( VolumeValue, “Volume” ); Lines of code that start with Plot1, Plot2, etc., draw graphic elements like bars and lines on the chart. When it comes to the Volume indicator, this line xqqcov code plots the price of the current volume for the bar, VolumeValue. This value is also due to the name “Volume” which allows a user to identify and change the design and style of the plot in the Format Analysis Technique dialog box. However, a person could only modify the default colors, widths, and styles in the plots. To accomplish our example, code should be changed.
Position the cursor following the line above and press Enter on the keyboard to create a new line. Now enter the following line of code: If Close > Open then SetPlotColor(1, Green); Don’t forget to incorporate the semicolon after the fishing line, or the code is not going to verify.
The line just added is a conditional statement saying, in layman’s terms, when the closing price (Close) of the current bar is more than the opening price (Open) of the current bar then alter the plot color (SetPlotColor) in the Plot1 element to Green (1,Green). Now press the F3 key or click on the Verify button to compile the code. Congratulations. The Amount indicator now plots as green when price closes over the open, and you will have created the first TradeStation indicator.
