Today after the FED announcement I was watching IQFeed and compared it to IB. At 2:23pm ES on IQFeed -1144 and on IB â 1138. There was a difference of about 2 or 3 points up to about 3pm and after that it was pretty much OK. It appears the IQFeed was about 30 â 60 seconds late compared to IB. I was considering switching to IQFeed but this leaves me puzzled. I just wonder if anyone is using IQFeed and what are their experiences.
