Help, please

[jojack]

I'm new to this and I don't know much about computers. I hope I'm in the right place. I have been trying all day to put a formula into the Formula Wizard and have not been able to do it. Can someone please help. I am trying to set up a 20 period exponential MA on a 25/175 Price Oscillator. Thank you.

You don't need an efs to do that. Set up a MACD study with the same settings as in the image below.
If you want the Oscillator to be based on simple moving averages put a check mark in Simple Moving Average (Oscillator)
