Can you give some more details?

For example show in an image what you mean with the "sense of the needles of the relay".

Would like to help, but have not a good idea what you are looking for.

sorry @erik_jan, relay¿?¿?

i could say: "I need to calculate the sense in which a line was created. Clockwise or reverse. The "orientation_extractor" does not give me the result I need"

Clockwise or Counter Clockwise is used for polygons. Are these closed lines?

In that case, use an AreaBuilder to build polygons and the OrientationExtractor will get you the right values.

they are not closed polylines, I already realized that if they were areas I was saying it ..... some other idea comes to mind ??? @erik_jan

Normally, i'd say horizontal angle calculator, if what you are after is something like compass points, but there was an error in this the last time i used/downloaded it, although that can be corrected.

If you're still looking for a solution, a small (annotated) screenshot might be helpful to better understand what you need.
