Custom filter for mtgox depth api request
On the v2 api, It's not possible, I guess, but they say here that it is, but that arguments to do so are not known. if you try any arguments the response is:

"error":"Invalid call method, please ensure query string is empty (min,max)"


that's why I think you can't, I guess it's the same for v1. Maybe you should think to do what you wanted to do another way, maybe updating your data with trades/fetch?since=1364767190000000
