Hi hazek, is it technically and philisophically possible to provide one common parameter "since"? This parameter is widely used among exhanges now.
It is possible to filter trades to return only new trades, trades with tid > since.
If yes, can we expect it in the near future, if not just give a reason.
And one question about Pusher stream api interface. Is it free to use? And if yes will you add order id field into full orderbook respones?
I don't think any such changes to our API are planed at this time but I'll ask our sys admin to consider your suggestion.
Pusher stream is not officially supported by us so I don't think we will have them change how it works as we only use it to stream on our website.
