1

Real-time: Live data is streamed back in real time. Market data subscriptions are required to receive live market data.

2

Frozen: Market data is the last data recorded at market close. Frozen data requires TWS/IBG v.962 or higher and the same market data subscriptions necessary for real time streaming data.

3

Delayed: Market data 15-20 minutes behind real-time (depending on the exchange). Automatically use delayed data if user does not have a real-time subscription. Ignored if real-time data is available.

4

Delayed-frozen: Requests delayed "frozen" data for users without market data subscriptions.
