That title sounds a lot like "it literally can't go tits up"

It's not your network. You confirmed that when you confirmed rtrader works fine.

Maybe default? Aurora is the "normal" connect point. Maybe also try the free version of rtrader

Ah, I see you're in Korea and using the Singapore gateway. Your data is originating from Aurora Illinois (regardless of the gateway you select), and getting pushed out to the Singapore gateway. You might try simply using the Aurora gateway, and see if that improved things. Cut out one of the...

Its not a Rithmic issue if it's happening regularly...I would have noticed. I assume you're connecting through Aurora?

On a possibility related note, Sorry, I mean what day/time of day were u having issues? I may be able to cross check my rithmic data logs. I store exchange timestamps, Rithmic timestamps, and local timestamps with microsecond granularity on trade prints

What instrument and time period?

So are Ferraris, but...

ABC, Robert, ABC !

Someone is...that's what happens in effecient markets.

Again, they don't have to. They are cash settled futures on the same underlying. Effecient(ish) markets keep them moving in lock step. And if it didn't, it wouldn't hurt cme at all.

They don't have to hire anyone. The prospect of an arb brings all the boys to the yard As for the half point disparity someone referenced earlier....I'm willing to bet half an ES point that was on last trade, not bbo

Yes i did...but I dont use IB for the algo stuff, I use Rithmic and a different FCM.

I don't trade the micro (unless I'm messing around in my ib account), but I do trade using the book on the minis. I'm automated and process every single book and trade event...I don't know how manual traders are able to do it, but that doesn't mean it's impossible.

The mini moves the micro, so I wouldn't even bother looking at the book for the micro. Watch the mini's book, but execute on micro if you're trading orderflow.

I compared them a few months back (maybe 6 months ago?) to see if there is any arb opportunity there using high-frequency tick by tick data from rithmic, with microsecond exchange timestamps on trades. There isn 't anything there, that I could see. They were almost in complete lock-step, and...

Umm, yeah, of course I am. Notice how I said "perhaps" ? Anyone who doesn't work at IB is purely speculating on what could have gone wrong.

I don't have an opinion one way or another. I'm just saying that MAY be the case.

I'd assume the data going into the charts is much higher frequency than that being used for portfolio updates, so may originate from different sources and take different paths to you. Not to mention.. pushing a time history of bars vs a snapshot

Different pipe?
