Suppose that I have two streams on the same connection, such as btcusd@depth10@100ms and btcusd@bookTicker.
Does the order that I receive payloads for different streams on the same connection indicate anything about the ordering of the relevant events?
For example, if I receive a btcusd@bookTicker payload after I receive a btcusd@depth10@100ms payload (on the same connection), can I assume that the bookTicker payload reflects changes to the book that happened after the @depth10@100ms payload was created?
It would be really nice if the depth and bookTicker payloads had a time field.
