Thanks Gldr, Who do you recommend for a broker with tick data feed? or is it possible to feed another data feed through Interactive brokers?
IB data is 'grouped' 'data not tick data. It is send about every second if there is a change
Let's be more accurate. IB data on the server level is real time tick by tick but on the TWS is snapshot which updates several times per second (I think 200-300ms) which is faster than you can blink your eye or click your mouse. The benefit is that during fast markets the data remains reliable without any lag.
