Bollinger Band modification MT4

 

Hi,

why is it impossible to change the deviation to a decimal number like 2.9?

It is crucial for my strategy, so I would be very, very thankful if there is a solution.

Thx

 
you have to use the bollinger band in the custom indicators, the normal one is limited to interger numbers. don't ask my why.
 

Thank you for this!

I thought these are the same..my fault!
