Problem - NASDAQ delayed feed data service, still pushing data when feed service is unsubscribed via API. API info - API subscribes to service at 07:35 US time and unsubscribe from service at 18:55 US time. We have observed that data are still push to application between 08:00-09:30 SG time and from 17:00 SG time during the unsubscribe timing.
SFC API will unsubscribe a record when all added clients of that record are dropped.
For example, if the application adds two clients for AMD.O, the application needs to drop that two clients in order to unsubscribe AMD.O.
