Strategy Tester not working on the MACD Sample

New comment
 
I have Metatrader 4 build 1.55. I would like to see how the strategy tester works before I set to work on learning the language and building my own tests. I add the expert advisor "MACD Sample" to my chart. It seems not to do anything. But it does put MACD Sample and a smiley face in the top right corner of the chart.
I then click on Strategy tester icon and nothing happens. If I right click on chart and choose Expert Advisors, Strategy tester is grayed out.
Does the strategy tester work? If so could someone please tell me what I am doing wrong.

Thanks
