EasyLanguage is really a proprietary programming language that was designed by tradestation developer and built into its electronic trading platform. It is employed to create custom indicators for financial charts and also to create algorithmic trading techniques for the markets. External DLL’s could be referenced using EasyLanguage which greatly extends its functionality.
The language was intended to allow development of custom trading strategies by traders without specialized computer training. Commands consist mostly of regular English words, that makes EasyLanguage easier to learn than more complex programming languages.
Even though the TradeStation trading package includes a wide variety of trading indicators referred to as analysis techniques, many people who use TradeStation develop the desire to incorporate or customize their own indicators using TradeStation code. This information will demonstrate how to make a simple indicator that displays the existing trading volume and also changes the visual indication of that volume to green when price closes up.
The simplest method to produce a new indicator is to locate a preexisting indicator that partially addresses the requirements then modify it further. With this example, the Volume indicator that accompany TradeStation offers an acceptable foundation.
To begin dealing with TradeStation code, first open the quantity indicator using the EasyLanguage editor. EasyLanguage will be the programming language that TradeStation uses. Start by right-simply clicking on any chart, then select Insert Analysis Technique from the pop-up menu. Through the dialog box that appears, select the Indicator tab, then scroll down to obtain the Volume indicator within the list. Click once on the Volume indicator row to highlight it, then click on the Edit EasyLanguage button underneath the list box. The EasyLanguage editor will open with all the code for your Volume indicator ready for editing.
EasyLanguage code is divided into three sections. The initial block defines the Inputs. These inputs can only be changed by formatting a warning sign once it has been added to a TradeStation chart. After the Inputs would be the Variables. These initialize once the indicator first launches in a session, along with their values are modified using code. After those two blocks is the actual code that executes. This is just what needs modified for our example.
First find the following line of code: Plot1( VolumeValue, “Volume” ); Lines of code that start out with Plot1, Plot2, etc., draw graphic elements including bars and lines on the chart. With regards to the Volume indicator, this line xqqcov code plots the value of the existing volume for that bar, VolumeValue. This value can also be because of the name “Volume” which allows a person to recognize and alter the design from the plot inside the Format Analysis Technique dialog box. However, a person can only change the default colors, widths, and styles in the plots. To finish our example, code must be changed.
Put the cursor after the line above and press Enter on the keyboard to create a new line. Now enter in the following type of code: If Close > Open then SetPlotColor(1, Green); Don’t forget to include the semicolon after the line, or the code will not verify.
The fishing line just added is really a conditional statement saying, in layman’s terms, when the closing price (Close) of the current bar is in excess of the opening price (Open) of the current bar then alter the plot color (SetPlotColor) from the Plot1 element to Green (1,Green). Now press the F3 key or select the Verify button to compile the code. Congratulations. The Volume indicator now plots as green when price closes above the open, and you have created the initial TradeStation indicator.
