Sets up a subscription and returns an initial snapshot of most recently completed samples specified by the parameters in the request.
Subsequent samples are delivered over the streaming channel. Most often a single new sample or sample update is delivered at a time, but when a sample closes, you will typically get two samples: The now closed bar, and the bar just opening.
