1) Is it possible to have different modes for different instruments ? Basically i don't want to stream unnecessary data. 2) Each Stream of data which we get from WebSockets, are they unique compared to the previous packet ? or are you guys send the previous packet again ?
1) Yes sure. When you do a "mode" request, you pass the tokens of instruments you want to apply the mode to. 3) Packets may have the same values as the last packet.
