Just 32x32 image space is, like, larger the the atoms in the universe. Even per-tick financial data is quite small in comparison. Or, from another angle, say you've got 10 ticks of a stock per second for 12 hours = 432,000 data points. This is the same as a single (relatively small) 380x380x3 image. If you assume there are roughly 30,000 instruments like this in the world of this volume, that's probably, I dunno, the number of images facebook sees in a second. Those are all guesses but you can see the scale of differences involved here.
