Thank you, the red and green for recent transactions was a suggestion we got a lot on the previous set of samples, but is obviously very easy to change. Noted on the network symbol will look for something else.
Yeah, I know, but being with a blue background just clashes. Granted, this is just one opinion.
I agree, for option 4 it would look better in white, will change on that one.
The use of the -> and <- in conjunction with the + and - seems redundant... Just one large indicator is all that's needed. Also, I don't think they need to be colored red/green as long as there is a bigass +/- where the arrows currently are. The colors wouldn't mess with your design that way, and still be entirely functional.
I like 3 and 4 best.
Example:

Doesn't mess with the design, is very clear.
The darkened boxes need not be so. The text should simple be the same darkness as the minus sign (I altered only the top 2 and did the box on the bottom one to get the idea across).
Crude 5 minute edit, but you get what I'm saying. The font I sued for the + and - kinda sucks. Just giving the idea.
Used the older design image.
PM me an .xcf... ;-)
