Something similiar to Exponential Moving Average(EWA)

[lily zou]

I need to do some statistic calculation for some application components. I know there is a indicator called EWA but what I want to do is to retrieve something like Exponential Moving Worst value, meaning the longest time value that component to take to do certain task, giving more weight to more recent values.
I am wondering if anyone knows any tools or any way to obtain this value ?
Your help is highly appreciated.

well, EMA is basic math formular that calculates weighted value, I don't know what Exponential Moving Worst is, but I would imagine it's also a mathematical formula you can use. You should be able to do it on Excel.
