Websocket or TCP or Push Notification ????
I am planning to build a mobile app to see the updates of stocks being added by the user as soon the price got updated.
1. Do we need to use Websocket or TCP or push notification in this case? Which one is better ?
2. Do we have any stock market test API's which supports Websocket or TCP or Push notification to cross check the feasibility, stability, reliability and latency ?
3. What are the differences between websocket vs TCP vs Push Notification ???
Need answers for the above three questions and the final decision as well. Please Suggest.
