High Pings & Latencies in Day Trading?

Quote from waggie945:

I have yet to use the brand new ETG-TRADER Platform that just rolled-out last week, but from what I understand the servers are in Chicago and Dallas, and run on an OC192 backbone that is 6100 times as fast as a T-1 line.

Not as fast. You surely mean "as wide"? Speed and width isn't the same. Once 6200 people are using it at T1 capacity, it's 'slower' than a T1.

Yes, I did mean to say "width" rather than speed, but at 10 Gbps for optical fiber, I'm not sure what a trader could use that would be commercially availible, and FASTER.

Any suggestions?

I don't know? Telepathic communication? I still love eSignal...

I've used E-Signal before and it just didn't cut it.
Way late.

Had to go back to using Realtick, which I am not that big of a fan of either due to reliability issues last year.

Hi waggie,

I made the same observation like you about late quotes.

I'm picking in because some weeks ago a lot was written about late quotes and so on.

Obviously, excessive latency time should contribute to quote delay. Although you do not say so explicitly, from my own (limited) tests comparing different quote vendors, latency/ping connection properties seem to have played only a secondary role.

Be good,

Cable vs. DSL...does either one "typically" have lower latency?

I have cable now and am seriously thinking of adding DSL as the primary (or backup) connection using the Hawking dual router. FYI, the Hawking FR24 dual router has been discontinued and will be replaced by the H2BR4 within a week or two.

Hi chisel,

I think it shouldn't make much difference. After all you are only talking about the hop between you and your ISP. From then on it's an entirely different ballgame.

Practically all of the 'latency' depends on the subsequent hops to your destination. The choice of ISP may be important. He could screw up right at the beginning, some ISP's may have better control over path choices than others.

If you are overseas, you can't take that big one hop out. Again, I think, Cable vs. DSL should be negligable, excepted for poor ISP's.

Be good,

Thanks for your explanation. All of the internet tech terms are spinning in my head! I keep repeating to myself: "more bandwidth does not necessarily = less latency."

Chisel, in layman's terms:

Ping/Latency = The time it takes for the water to shoot out the other end of the hose (pressure)
Bandwidth = The size (width) of the hose

Both are important if you want to push water.

Good explanation, Scientist!
