Questions regarding IB API

[leonbrag215]

That is indeed an appropriate example.
What I was refering to is shown in this screen shot:

In the lower right hand corner you see an order for GOOG. Left next to it you see a purple arrow symbol. The colour code indicates the status of the order and whether it is at IB's servers or at the exchange.

Thanks I don't plan to use TWS all that much only the gateway, but it is indeed very informative.

I do not use IB but another broker. In my opinion this is how it functions. I use a REST based API. I open socket streaming which allows me to receive updated market data in a realtime. When the Brokers ticker plant gets a real time update from the exchange, their system processes an event that pushes each change element downstream. Have been using this platform for a an year and works well.
