IB Market subscription ?

[MIGS 3]

Newbie question, I already have the DAS Deluxe Plus subscription that comes with totalview, etc...(with IB account)....  is there a reason to also subscribe to IBKRs market data?, I won't be using TWS for trading.

If not using TWS you don't need to pay for market data to IB.
