session = blpapi.Session(sessionOptions) if not session.start(): print("Failed to start session.") return

subscriptionRequest = session.createSubscriptionRequest() subscriptionRequest.set("securities", "AAPL US Equity") subscriptionRequest.set("fields", "PX_LAST")

session.subscribe(subscriptionRequest)

eventCount = 0 while(True): event = session.nextEvent() for msg in event: print(msg) if event.eventType() == blpapi.Event.RESPONSE: break

session.stop()
