This is the Drawing function of SnakeForce.mq4.

After calculating the variable "Mart", it calculate ForceUp, ForceDown, ResistanceUp, ResistanceDown in this function, but I don't understand what do the numbers 5 and 9 mean here.

I know that this indicator repaints. I just want to know how to calculate Force and Resistance.

Thank you for your help.

Naguisa Unada: what do the numbers 5 and 9 mean here.	It means 5/9 (0.5556) of the value in between. Nothing more.

Oh, is that something like that?

Thank you very much.
