This is a very early version of the indicator and has pre-set values. I personally use it among a 5 minute chart for daytrading.
NOTE: Have in mind my indicator as ny other is not perfect, it might give fake signals. I suggest using Williams , and with it. Best of luck. Follow my predictions under your own risk.
