TradeStation EasyLanguage Programming Requirements Definition – Before you start a TradeStation EasyLanguage programming project, requirements may be submitted in writing via email. A programmer may contact you with a lot more questions or clarifications regarding the requirements, when necessary. You are going to then obtain a Strategy Specification Document. This document should approved on paper before we are able to give you a bid or begin the project. After the requirements have already been approved, we will give a fixed bid for the cost of the project with the estimated period of completion. Fixed bids will be based on documented and approved requirements, and all of changes will need a different bid.
EasyLanguage is really a proprietary programming language which had been developed by tradestation programmer and built into its electronic trading platform. It is actually used to create custom indicators for financial charts and also to create algorithmic trading techniques for the markets. External DLL’s may be referenced using EasyLanguage which greatly extends its functionality.
The language was meant to allow introduction of custom trading strategies by traders without specialized computer training. Commands consist mostly of regular English words, making EasyLanguage easier to learn than more advanced programming languages.
Though the TradeStation trading package comes with a multitude of trading indicators referred to as analysis techniques, many people who use TradeStation develop the drive to add or customize their own indicators using TradeStation code. This information will demonstrate how to make a simple indicator that displays the present trading volume and in addition changes the visual indication of that volume to green when price closes up.
The easiest method to create a new indicator is to locate an existing indicator that partially addresses the prerequisites and after that modify it further. For this example, the quantity indicator that is included with TradeStation offers an acceptable foundation.
To begin working with TradeStation code, first open the amount indicator using the EasyLanguage editor. EasyLanguage is the programming language that TradeStation uses. Begin by right-simply clicking on any chart, then select Insert Analysis Technique from the pop-up menu. From your dialog box that appears, select the Indicator tab, then scroll down to find the Volume indicator in the list. Click once on the Volume indicator row to highlight it, and after that click the Edit EasyLanguage button underneath the list box. The EasyLanguage editor will open with all the code for that Volume indicator ready for editing.
EasyLanguage code is divided into three sections. The very first block defines the Inputs. These inputs can only be changed by formatting a warning sign once it has been added to a TradeStation chart. Following the Inputs are definitely the Variables. These initialize if the indicator first launches in a session, as well as their values are modified using code. After those two blocks will be the actual code that executes. This is just what needs modified for our example.
First get the following collection of code: Plot1( VolumeValue, “Volume” ); Lines of code that start out with Plot1, Plot2, etc., draw graphic elements like bars and lines on a chart. When it comes to the quantity indicator, this line xqqcov code plots the price of the existing volume for that bar, VolumeValue. This value is also given the name “Volume” which allows a user to identify and alter the style from the plot in the Format Analysis Technique dialog box. However, a user can only change the default colors, widths, and styles of the plots. To complete our example, code must be changed.
Position the cursor right after the line above and press Enter on the keyboard to make a new line. Now enter the following line of code: If Close > Open then SetPlotColor(1, Green); Don’t forget to add the semicolon at the conclusion of the line, or the code will never verify.
The fishing line just added is actually a conditional statement which says, in layman’s terms, when the closing price (Close) in the current bar is in excess of the opening price (Open) in the current bar then modify the plot color (SetPlotColor) in the Plot1 element to Green (1,Green). Now press the F3 key or click the Verify button to compile the code. Congratulations. The Quantity indicator now plots as green when price closes above the open, and you will have created your first TradeStation indicator.
