InteractiveBrokers, Oh My!

Quote from TGM:

thanks ---learn something new everyday!!

wtf is the "range for the domain"??? i dont understand the joke?? something I should know about??

average for ib ping is 38ms for me

LOL. No I meant to say Thank you to the poster named RANGE for providing the address to ping. The 208.245.147.9 that another poster earlier in the thread gave, timed out for me.

38ms is great. I'm getting avg 9ms. But that might be a factor of a few things. When I run a trace route, I only have to go through 12 servers to get to gw1.ibllc.com.

Here, try this. In that command prompt type:

tracert gw1.ibllc.com

You'll see a list of all the hops (servers) you had to go through to reach IB. And you'll see which one(s) is(are) the slow poke(s).
 
"pinging" ib, all the #'s I see are 10ms or under. I guess that is decent?? Or is it the last number that is important (TTL)? I'm on optimum online too.

10 hops, each 10ms or less. So thats about 100ms total?

<10ms and under is not just decent, it's great.

The only number you have to worry about is the one that the ping command gives you. The tracert command, pings round trip each of the servers individually. So you can't add up all the numbers to figure out your total ping. The ping command does that by round trip pinging IB which includes all the the servers found in the tracert. But it's not pinging all of those servers seperately.

That was probably a lousy explanation and could be a bit off technically speaking but the gist is, what you get with the ping command is the actual time and all that matters.

I have to go through 17-18 hops and 38ms. I had to go through about 5 and then all this exchange servers and then Timberhill. Pretty wild stuff. learning something new today.
 
I have a green light connection OK but get no quotes (chart is working). Ping test OK. Tried 208.245.147.9 connection got bunch of good results(?!) at the bottom it says it doesn't connect to 208.245.147.9.
Can anybody explain what it means? Why it gives me bunch of results and then it says it doesnt connect to ISP I tried to "trace route". It seems strange to me ( I have no clue though) that it would be providers fault since somebody else has got the same problem. Thank you very much.
 
Quote from TL Trader:

It apparently varies in different parts of the country but I have problems with comcast constantly here in the southeast.

I have latency problems with comcast (north TX). It rarely causes problems with my trading applications, but it's horrible for voip (vonage).
 
Before anybody takes time to respond it is working now. During the day my connection slowed down for an hour or so. I restarted, got everything working but quotes. Something just wiped out my settings. It took me a while to figure it out since it never happened to me before.
Now I don't understand why trace route says not connection with 208.245.147.9.

P.S.I hate dealing with things I don't understand.
 
Again, I'll say it, the title of this thread is stupid. Yet another thread blaming IB for something that isn't there fault - lets stick with humble realistic titles until we know its their fault and then, if they are arrogant, we can stick it to them. Otherwise the thread starters and the anti-ib hangers on just look like dickheads again.

On the subject of how long a ping response (the round trip delay to the IB server/router and back) is OK --- many of us trading from overseas have pings of 250-350ms and thats ok.

Your response time to a stimulus typically measures 500ms-750ms so the one way delay of a 250ms ping is about 125ms so it adds 25% to a reasonable response time. So overseas latencies are too high for machine based scalping strategies but for normal trading where the order may even reside on IBs server they are just fine.

The issue occurs if they start to push up and maybe vary when your ISP is busy (too many kids on line, or the teenagers are home and downloading those big porn pics and movies). Also at this time some ISPs drop packets to keep the apparent latency low and keep things moving. TCP/IP recovers from this but the recovery is A BAD THING FOR A TRADER.

We need consistency. So get a good ISP who doesn't EVER overload their backbone links or key routers. You need to get one who cares about keeping load low and performance good.

Finally just because it works in one city doesn't mean that it will in another city. An ISP's policies for loading their links/routers can be fine in city A if the load is ok still ... but in city B its too high but hasn't got to the point where they add capacity. So for a trader its just bad news.

I don't know who the bad/good isps are in the US. Here I choose to use major Telco services that are maybe twice as expensive as the cheapies ---- but my links to IB dont drop out and I get great service "from IB."

This is a business guys. We need to treat it as such --- or we're just gambling.
 
Quote from kiwi_trader:

PS. I dont work for IB but unlike some of the halfwits who complain about them I've had enough brokers to know whats good, whats bad, and whats my fault. Wake up guys!



But yes, I think Merrill Lynch would love you. You should go their and take old lawnmowery with you. They love idiots just to death - its their specialty :)

WOW! your're one angry dude.....
if you don't work for IB perhaps you should look into it as you sure sound like most of their support/ employees who answer the phone.
We experience data losses, loss of connection, wrong data with reference to high and low's of the day, long delays (minutes)on executions in stocks on the NYSE and have be told that the quote is wrong, etc..these are daily issues...with most brokers I agree..but we have a full business line ....equal to a T1..
We find that when the above issues happen it does not effect everone..and upon inquiry we/I have been told it depends upon what server you are logged on too.
I dont' know this individuals situation...and I agree the title is interesteing but that doesn't mean anyone who losses connection is an idiot and does not treat their trading as a business.
These issues happen more when we have a volitile/volume day..perhaps IB should look at creating larger capacity servers..and you can bet...next week..options expiry.. this happens thurs and friday...just par for the business.
