Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with EasyLanguage.

What does this basic EasyLanguage code do?
Inputs: Price(NumericSeries), Length(NumericSimple);
Vars: Avg(0);
Avg = Average(Price, Length);
Plot1(Avg, 'Avg');
This code calculates the average of a price over a certain length and plots the average on a chart.
What will be the output of this EasyLanguage code snippet?
Vars: intrabarpersist counter(0);
If MarketPosition = 1 then counter = counter + 1;
Print('Counter: ', counter);
This code will increment the counter by 1 every time the market position is 1 and print the value of the counter.
What does this EasyLanguage code do that involves array manipulation?
Array: MyArray[3](0);
MyArray[1] = High;
MyArray[2] = Low;
MyArray[3] = Close;
Print('High: ', MyArray[1], ' Low: ', MyArray[2], ' Close: ', MyArray[3]);
This code creates an array with 3 elements, assigns the high, low, and close prices to the elements, and then prints these values.
What does this EasyLanguage code do that involves threading or concurrency?
Vars: intrabarpersist counter(0);
If LastBarOnChart_s and counter = 0 then Begin
  counter = counter + 1;
  Print('Last bar on chart.');
End;
This code prints 'Last bar on chart.' only once at the last bar on the chart. The counter is used to ensure the message is printed only once, demonstrating a basic form of concurrency control.
