Pinescript - Convert Wells Wilders MA v2 to v4

I have a function to calculate Well Wilders MA for v2.

It's used for calculate DMI Stochastic Extreme 

wwma(l,p) =>
wwma = (nz(wwma[1]) * (l - 1) + p) / l

I'm going to convert it to v4

And I got error: Undeclared identifier 'wwma'.

Pinescript v4 doesn't allow recursive function.

Do you have any suggestion

When using recursion in the v4, you first need to declare your wwma variable. In your case this would lead to:

wwma = 0. 
wwma := (nz(wwma[1]) * (l - 1) + p) / l

Here you declare wwma as a decimal by assigning 0. as value.
