Help: bollinger bands setting

New comment
 

Hi I need to set the bollinger band as below :

 Upper Band Deviation = +.382

Lower Band Deviation = -.382  

 I tried many times on MT4 but failed.Does anyone know how I can do this kind of setting ? Thanks in advance.

  1. "Doesn't work" is meaningless - just like saying the car doesn't work. Doesn't start, won't go in gear, no electrical, missing the key, flat tires - meaningless. There are no mind readers here.
  2. All BB allow a multiplier from one standard deviation, (most now use a double.) It makes no sense to set a line to an absolute value. (+.382)
