Thanks for the contribution.

In fact, we can almost add "many more" math functions if we want. The important question is, "are the added math functions useful to stock indicator builder"?

In another word, have you come across any stock indicators, which require "mean" and "mode" functions?

There isn't any official stock indicator uses median or mode.

I do agree "Median" have no real usage most of the time, I just added in just for the sake of Math Statistic completeness.

But i do use a lot "Mode" in my own custom indicator to indicate what is the most common price a stock falls at, hence knowing is a good time to buy in that stock

Example: Say i identified a potential stock and kept in my watchlist but price is consider high now, I wanted to create a BUY SIGNAL indicator for this stock when the price is below or equal it's support price (the lowest price that it always falls at in past 30days).

I feel this is when "Mode" is more useful instead of "Mean" in this situation

The indicator will goes like this,
Real Time(Last Price) <= Relative(Mode(Days:30days, Last Price)) -> ALERT
