Thinkscript fold equivalent in ninja

[csrkkalyan]

Hi there,

Looking for thinkscript fold equivalent in ninja, here is my simple thinkscript logic:

def data = fold i = 0 to 10
with s
do s + (if Close > getValue(Open, i)
then 1
else if Close < getValue(Open, i)
then - 1
else 0);

Hello csrkkalyan,

I am not certain on how that logic would execute, is that executing a loop from 0 to 10? Can you provide an explanation of what the variable data is and how that is used? That does not appear to be used in the following lines that you provided. The parts below def data appear to be if conditions, can you confirm that as well?

Hi Jesse,

Thanks for your response. Yes, this is kind of looping concept. The fold operator allows you to perform iterated calculations. examples can be found from below url:

Hello csrkkalyan,

The equivelent of that in C# would be a for loop. You can read about C# for loops here:

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/statements/iteration-statements

for (int i = 0; i <= 10; i++)
{​

}
