Tutorial 113 | Using data from an Excel sheet to update an EasyLanguage program

Use data from Excel spreadsheet in an EasyLanguage program

Tutorial 113 demonstrates how data stored in an Microsoft Excel spreadsheet may be used in a TradeStation EasyLanguage program applied to a chart. In tutorial 112, I demonstrated passing data from TradeStation to Excel. In tutorial 113 the data is flowing in the opposite direction.

The tutorial also demonstrates the use of the Drawing, ChartingHost and Timer objects as well as the use of methods.

The program is available for download for a small fee or for FREE to Gold Pass members.

What does the program do?

Parameter values stored in the spreadsheet

Tutorial 113 plots 2 moving averages. The lengths of the moving averages are determined by values stored in a spreadsheet in specific cells (G1 and H1). When the value in Excel cell G1 is changed, the program starts plotting an updated value for the moving average.

Tutorial 113 also creates text objects that display the current values of the parameters on the top right of the chart. These values are updated when the value in G1 is changed on on each new recalculation of the program. These text objects are re-positioned if the size of the chart window is changed. An additional text object is added to the chart on the current bar whenever the value of G1 is changed. This object remains with the bar where it is originally positioned.

Tutorial 113 applied to a 15 second bar GBPUSD chart. Notice the red line. The length was set to 100, then changed to 50, and then back to 100. Notice how the line diverges from the yellow line and then returns to it.

EasyLanguage technical lessons

In the tutorial video and the program comments you will learn:

  • How to use the Workbook class
  • How to use the Timer
  • How to use the ChartingHost object
  • How to create methods
  • The use of an intrabarpersist variable

Although I do not use it in the demonstration video, the objects and their associated events can be created using the toolbox. The resulting code can be copied from Designer Generated Code, into the TradeStation Development Environment.

This tutorial was developed using TradeStation 9.5
Version: 9.5 (Update 15). I had major problems with update 14 running under Windows 10 (totally unrelated to this tutorial), with TradeStation continually crashing whenever I tried to open a workspace or to create a chart.

Inputs

Tutorial 113 has a single input that tells the program where the Excel spreadsheet is located.

FileName( “C:\Program Files (x86)\TradeStation 9.5\MyWork\tutorial113.xlsx” );

Make sure you have an Excel file in this location.
