Just an observation with regards to the pusher feed, it looks like it has changed since I last looked at it a few weeks ago, it appears the depth info has been modified.
Before we had:
data.amount_sum
data.amount
For each order update. I assume that amount_sum showed the total amount of volume at that depth, and the amount was what the last change was. Now the data.amount_sum part of each message has gone and we only have the amount.

It also appears the bitstamp home page is no longer updating the live orders. I'd be interested if anyone else has any idea what the data.amount currently stands for, it is the change at that price, or the new sum at that price? 
b) You are about to embark on a long, frustrating journey, my friend.
data.amount appears to be the CHANGE. I agree that data.amount_sum would be nice.
I am subscribing to channel "live_orders". Does anybody have any better suggestions?
