I just did and it looks great, although I think it would be nice to have current rate as well (like to have 4 buttons of Live, Max, Ave and Min).
Great, yes actually will keep only three Max, Live and Min, No need of average.
I noticed it takes two increased rates to change the red background to green (although the green arrow changes accordingly) but it takes only one decreased rate to change the green background to red. Any reason for this?
Idea was first price down will turn the arrow down and second price down will make it red and yes one price up will change and color and arrow too.
But I noticed there are some glitches and I'm working on it.
Also I could not find a suitable image to show price is stable or same so by default it it will be either up or down depending on current price and previous low and high price.
