The server had a blip making me lose about an hour of data, but I was really excited to show it to you.

This is pretty cool!

What do you use for a stack?

Super small. Node JS/express and flat files for history.

Firstly, that's very cool. Well done!

Secondly, I know hardly anything about bitcoins - but here all I see is an arbitrage opportunity. Buy bitcoins from BTC-e and sell them on MTGox, which seems to be consistently around 150 (I assume USD) different.

Am I missing something here?

Selling on MtGox, from what I understand, takes days (if not weeks). Buying is more straightforward.

It is impossible to withdraw USD from MtGox.

It'd be great if you could include an overall average of the exchanges and also convert USD into other currencies.

I want all time history! But on serious note, if you could dynamically add other "indexes" as well as show other currencies besides USD, that'd also be good. But I'm assuming this is a side project you're just messing with?
