It's pretty close S2W. I'm gonna mess around with the tones of the glow a bit and see what I can come up with. The image itself looks a bit sharper than the precision icons I used as those started out 80x80 and by the time I stretch them to 256x256, they get a bit distorted. So I may just use your icon and make all of the rest of them to match it.
Edit: If I use your icon as is and remake the rest to match, I can easily come up with a better stocks and weather icon. Looks like I have a bit of work to do.
