Today you will discover how to use the loop in EasyLanguage for TradeStation and MultiCharts.

A loop is a code instruction that repeats a sequence until a specific condition is met.

It’s a fundamental programming idea that is commonly used in writing programs.

Suppose we have to create an indicator ShowMe that highlights 5 consecutive lower lows.

We can write this code:

   Signal (false);

Signal = Low<Low[1] and Low[1]<Low[2] and Low[2]<Low[3] and Low[3]<Low[4] and Low[4]<Low[5];

If Signal = True then


This is a very stressful code, imagine if you need to use more candle then five.

We can write this code using a loop in EasyLanguage for TradeStation and MultiCharts. With the loop, you can repeat infinite times certain actions.

The most common loop is the for-to loop. Whit this loop you can execute code repeatedly until the loop count reaches a certain value.

The program increases the loop by one at the end of each cycle.

We set the starting and the ending value of the loop and that’s all.


for counter = 0 to 5 begin

Print(“Value of ‘count’: “, count);


//> Value of ‘count’: 0.00
//> Value of ‘count’: 1.00
//> Value of ‘count’: 2.00
//> Value of ‘count’: 3.00
//> Value of ‘count’: 4.00
//> Value of ‘count’: 5.00

Now we can modify our Show Me Lower Lows indicator with this loop instruction.

This is the code with loop in EasyLanguage for TradeSTation and MultiCharts


   Signal (false);

Signal = True;

For x=0 to LookBack-1

Signal = Signal=True and Low[x] < Low[x+1];


If Signal = True then


This is the TradeStation or MultiCharts charts with our Show Me indicator.


You can use the loop in EasyLanguage also to compare many values and find the higher or the lower.

myValue = -999 ;

for x = 0 to 200 
if High[x] > myValue then
myValue = High[x] ;
end ;
