Question about an input on this fractal indicator

Does anyone know what the "equals" input on this does? I thought maybe it meant total number of candles in the fractal, but no matter what I change "equals" to it doesn't seem to change anything.

I've run into similar situations and learned eventually that some inputs just don't do anything, not all indicators out there are perfectly made and sometimes a coder would create a parameter and forget to write a code related to it
