Hi,
this is my first post here. I just discovered Zorro and this is a gem! Thank you for your hard work!

I've opened the indicator source file to take a look at the fisher normalization function.
I have experience in C/C++ but this is the first time I look at C-lite and this syntax is a bit confusing for me:



Why assigning FN[0] just before the return?
like:


And then I figured out FN[1] is assigned previously in the function as the input Data[1], but not as a Fisher transform.
The return could have been:


I don't think this is the case and must mean something I don't know and I can't find on the net.

Thanks for your help!

This code

return FN[0] = Fisher(Value) + 0.5*FN[1];

sets FN[0] to the returned value.

I suppose that FN is a time series, and FN[1] is then the value that the function returned in the previous call.
