Poll buffered ticks
ws_pollRead-only
Retrieve buffered live market data frames non-blockingly; omit after_seq for a tail snapshot or pass next_seq from prior poll for incremental updates.
Instructions
Read buffered live frames. Omit after_seq to get the most recent frames (a tail snapshot); then pass the returned next_seq on subsequent calls to get only newer frames. Non-blocking.
