Price difference

[wheezergeezer]

I'd noticed price diffence's a few times in the past week, yesterday I watched WFT at 15:06 (time) the TWS was showing ask 73.40 but the charting (IQ feed) was asking 71.27 ? all other stocks were pretty much even, has anyone else had this or is my system playing up?

I've noticed differences between TWS and OpenTick. It might be because the different feeds are distributing data from different sets of exchanges/ECNs. eg in the example above IQ feed many be including a quotes from an ECN or some other source that IB doesn't.

Edit: On rereading this, either TWS or IQ feed is way off - somebody is wrong. But my comment probably applies in other cases.
