DSL, Cable modem or Satelite?

  1. Which of the three is most effective when it comes to daytrading? My style is one of speed, looking for quick access to the markets. It seems to me that cable would be most advantageous since it can send as much as 10Mbps of data downstream. The downside is however that it becomes slower when other users are on your same line. But can cable become slower than the maximum 384kbps that DSL offers? Any help from experience would be greatly appreciated.

  2. the maximum 384kbps that DSL offers...

    Might be the area I live in (although it's a fairly small city) but my DSL is currently rated at 768kb, and the provider offers 1.5mb DSL for about $20 more per month. Another avenue to consider, if speed is of the utmost importance, is a fractional T1 line. It will be more expensive than cable or DSL, and is not offered in all areas, but it is fast.

    BTW, this would have been an excellent thread for the Hardware forum. :)
  3. Satellite will give you delayed data, not shure exactly how much delayed, around 0.5 - 1 second would be my best guess, so if you are scalping futures, be careful with that one. Also, always have an analog modem turned on, ready to connect to the backup ISP. DSL, Cable do fail at the most inapropriate moments. Murphy's Law I guess...

  4. Satellite would be the laggard of the 3 options. I'd say the choice is really between Cable and DSL. However, it really depends on your area and what is offered. I say this, because not all areas offer the same type of service in either category. I've heard just as many horror stories about both cable and dsl. I've also heard rave reviews between both options as well.

    In general DSL will be slower than Cable when you compare top end speeds. However, in real world performance, it really don't make much difference as both will get the job done nicely. Heck I know a lot of folks with 56K modem connections and they have no problems what so ever, as quotes do not take that much bandwidth at all. Unless of course you are sucking down hundreds and hundreds of quotes. :p

    I'm on a Cable connection myself. I currently can download at 3.2Mb/s and upload at 512Kb/s. My ping times are generally around 30ms depending on the site I'm pinging. As far as other people using the same node as me and slowing me down, well that just hasn't happened at all here. I've had this connection for over 1 year now and I know other people around me have the same as well, and I have never had any speed problems. I can obtain the 3.2Mb/s at any time night or day. However, this is my situation only. Not all areas will be the same.

    The DSL offered in my area maxes out @ 1.5Mb/s and actually costs more than my cable.

    If you want a little bit more reliability (or so I've heard) and are willing to pay $500 to $1500 per month, then go with the T1 line. With a full T1 you will be able to download and upload at a max speed of 1.5Mb/s. You will not get a speed advantage over Cable here, except on the uploads. Top end DSL lines will also keep up with the T1 as far as download speeds goes. The extra money, which is quite a bit, considering both Cable and DSL can usually be had for around $50/month, will only get you a little more reliability. Not really worth it, unless your Cable or DSL are constantly going down in your area.

    Now if you really want overkill then there is a T3 option which will get you the 10Mb/s up and down. However, it can cost several thousand per month.

    If you have both DSL and Cable in your area, then just give either one a try and see what you think. You can always cancel your service and go with the other if you so choose later on. I'd try Cable first though, however I'm biased. :D

    Hope that helps,

  5. I had dsl thru speakeasy, one of the better providers that is still in business. Then I installed cable and cable wins hands down. Cable is much faster, more reliable and less expensive. Also, dsl companies try to lock you in for longer terms due to to higher operating costs. DSL is dependant on the structure, quality and distance from your local telephone company. Speakeasy is still trying to charge me for service they did not provide because I cancelled before an entire year of service. Many DSL companies have gone out of business, and the remaining ones are on very shaky ground.

  6. This issue is not as simple as comparing speeds and prices. If it were that easy, cable would be the choice. In my experience, you really need to hook them both up and use them side by side. The real world problems you encounter will involve bogged down routers on the route to the data company's servers, and there is not much you can do about that except use another data company or switch to DSL if you are on cable. QCharts is good because they have server farms scattered around the country. If one is slow you cna switch to another. RealTick and AT apparently come from Chicago and I have had problems with each at times because of bad routers at the chicago gateway.
  7. I am in a small town near Boise Idaho. I have both cable and dsl (just in case). While the cable looks better on paper, I actually have better luck with the dsl most of the time. The speed is constant, and it is generally quite reliable. I use one hook-up for my quotes and charts, and the other for TWS. I have all of the software set up on both of my computers so that if one connection goes down, I can just start up the needed program on the other computer. It leaves me short of monitor space until the other connection comes up, but I think I have only had to do this once in the last few months since I got the DSL. It's nice to have the back up when you need it. At this point, if I had to choose one, I would go with DSL. I am sure that location and local providers have a LOT to do with which is better in actual use.
  8. After comparing Adelphia cable and Verizon DSL in the Burlington, Vermont area I am dumping the cable. Advertised speed means nothing to these providers - they are not providing any sort of guarantee. My cable advertises over 1 mbps, while the DSL advertises 768 kbps. After several months of running them side-by-side and using ping plotter to track performance under various apps the DSL wins hands down. With several universities near me, the cable sharing issue is significant as my cable speed, which always sucks wind in the 400k area, really crashes in the evening when all the kids are on Kazaa, and can go as low as 180k. Worse than speed is the packet loss issue. I've seen much more packet loss on the cable line, and in general up to 50% more hops to get where I'm going than the DSL takes. My DSL speeds are consistently 500 kpbs down/ 100kbps up and often faster. All this said, your results will vary with location and carrier so proceed skeptically but this may be applicable to others in the New England area and elsewhere. Don't do Sat unless you have to, the latency is bad.
  9. Eldredge,

    We are from the same neck of the woods. (Nampa myself)

    Did you use cable when it was @home or since it became Cableone? It was nice before cableone took over because they didn't cap the speed, and it was cheaper.

    It's good to hear a favorable opinion of DSL in case I need another option...
  10. Hi folks,

    I have problem: why does mycable always have more packet loss compared to dial-up. I did ping to IB gateway(gw1.ibllc.com) and Qcharts server(sterling-r02.quote.com) during heavy load traffic at 9:30 to 10:30 am.

    Anyone can give explanation ? I will appreciate it.

  11. Some years ago had satelite, which wasn't very reliable, weather and positioning problems, however it may be better now but I wouldn't use it again.

    Have had cable for 3 or 4 years from Comcast / excite@home and it was fast and dependable until excite went out of business. Now Comcast is switching everyone to their own system and here in the northeast it is a nightmare. Computer hasn't functioned right since downloading the new system and speeds vary wildly. Tech support gave me the wrong info after hours on hold when I did finally get them to answer. If you are considering Comcast as your cable provider I would wait until they get it right, if ever. They are changing 1 area at a time and this may go on for quite awhile. I see myself going to DSL soon.......Pat
  12. After further consultation, I'm going to try cable. One more question: Are there different types of cable modems that vary in performance? I heard that a commercial cable modem is on the market, but I'm not exactly sure how performance would be enhanced with a better modem.

  13. brokershopping,

    I'm in Eagle, nice to know there is at least one other trader in the area:) I did have cable with @home, and it was much better. My DSL is with Qwest/MSN. They really messed up the initial hook-up, and it took a lot longer than they said. Once I finally got it running I was pleased though. One bad thing though, I get TONS of spam on that account some - of it is for porno which really irritates me. I would like to know how to stop the spam.
  14. Eldredge:

    Unfortunately there is not much you can do. You can be sure
    that some *ss (*=a) somewhere has sold your email address
    on! I have been getting spam on my email address. It used to
    be the case that porn spammers used to use some hotmail or
    yahoo etc address. Now they have become very bold and actually
    started mass spamming using their own registered domains.

    Anyway what I have started doing is that I do a lookup
    at the domain registrar, find the administrator and register
    his email address on a few other different porno sites. That
    will teach 'em a lesson :D


  15. i am in the northeast, using a cable modem, dl is around 240 up 128, at peak, offpeak, i get 1mb dl, 84k up, speed is fine, but my cable provider keeps going, 3 or 4 times a month sometimes for days at a time. cant have that. looking to get adsl or t1. got a quote from a t1 provider for 1100 a month, thats with 24/7 support, and they say t1 has 99.9% uptime. i need 99.9% uptime. is the 1100 quote a good one, i am still looking, and would you guys recommend a higher dsl at 764, but with dsl u have to share don't you? anyone here use t1 would you recommend it, or adsl, and what do you think of the quote, that doesn't include the router. basically, im looking for 764/up/dl and 99.9% uptime do any forms of dsl provide this. would like to get a quote in the 600 - 700 range. cable is great for home use, but not business, especially trading imo. thanks
  16. If DSL isn't available you might try asking your local phone company about ISDN. I know it is the "old" technology but you probably will find it more reliable than cable (can keep the cablemodem as well as it will be faster) and you can probably come up with a deal that will save you a lot of money over a T1. This assumes that speed ISN'T your primary desire. If it is, ISDN would be a BIG step back for you speed wise from T1. It is also possible that having a dedicated trading connection on ISDN, and a separate cablemodem connection (at faster speed) is a combination that might work for you. I'm not really an ISDN expert, just passing an idea along.
  17. Tripack,
    thanks, i am not familiar with isdn, i will look into it. its hard for me to believe that others are not having the same problem with cables reliability, i can see a few min or hours, but it goes for a day or two they say dns problems at their server farms
  18. I'm usually not lucky in life, but (knock on wood) in 4 years my cable has been down perhaps a composite 24 hours.
  19. Cable...then DSL...finally satellite.
  20. ISDN usually runs at 64K (at least here in the UK). It is like using
    a modem at full strength but much more reliable.. if you are
    used to anything faster then you wont like it ;-)
    You can get 128K ISDN which usually uses bonded channels
    meaning that it is basically over 2 telephone lines. Yes that
    means your phone bill is twice the usual for internet calls @128K.

    I had ISDN for 2 yrs and now I have DSL. I dont think I could put
    up with the slow speed .....
  21. If you do decide to go with satellite because that is your only option, then Starband is a possibility, but it is picky about what data feeds it works with.

    Check out http://www.starbandusers.com discussion forums (modest annual fee) and you should find entries on what works with Starband and what doesn't.

    Website for Starband itself: http://www.starband.com

    Mr. Toad (who used to use Starband and dumped it when DSL became available)
  22. I had a cable hookup from @ Home for many years , It would drop the connection a lot , especially during the last 30 minutes of the trading day ( right when the kids got home from school) .
    @ Home could never figure it out .
    I got DSL connection as backup , never had any real problems with that except that the download speeds were a bit less.
    Now I have a fiber optic Cable connection that smokes everything out there, never a problem and the speed is double that of anything else out there.
    This Fiber optic connection is offered by Gemini Networks and is only available in a few areas.
  23. how much for the fiber optic cable, just did another test now at 128 dl peak off peak same up stays around 84k. i guess im looking for 512 dl. up doesnt matter. need uptime more reliable than cable, do any forms of dsl or sdsl or adsl fit into these categories, i am getting a lot of different opinions on this, some say dsl is shared, others say certain types of dsl is not shared, i dont think i can do 1100 a month for a t1 plus the standard csco router, plus installation. comments surely appreciated thanks
  24. $ 35 a month .
    It is not available in many areas yet.
  25. Splat - ISDN tariffing is different in the US (at least in the Chicago area). I've got an ISDN line connected to a router that supports dual channel connections (128K). Since the point of presence that I connect to is less than 8 miles away, the cost of establishing the link is 8 cents and there are no per minute charges.

    I have the router configured to keep the link nailed up, so it's basically an always on 128K connection like DSL. Will probably switch to DSL when they finally make 384K or 768K DSL available by me.
  26. ArchAngel,

    You are in the Chicago area and your area does not have access to DSL? What area is that?

  27. I dug around a little, and Gemini is privately held and would appear to be in early stages. The website (www.gemnets.com) is sparse, but lists 3 ISP's that through which there is some availability, it would appear only in some areas of CT.

    Does anybody know more about this technology base?
  28. I am one of those lucky ones who has this service. I have a DSL backup and had @ home . Gemini blows everything out there away. Now who knows what will happen if thier network were to get saturated like @ home did.
  29. is gemini public if so whats the symbol, is it available in pa thanks
  30. disregard that previous post
  31. Here in europe satellite is much faster. Over a regular Cable or Dsl i have up to 500ms delay... regularly around 120ms delay. And you only receive the quotes you select. With the satellite you save the quotes on your local server and with the satellite I have a max delay of 50ms.

    So for us here the satellite is much faster. I don't know how the delays are in the USA.
    And with the satellite you take down all the information at once.. downstream up to 20MB/s and save them on your own server. so when you look back in the history charts are build up much faster. when you go over a TCP/IP you first have to download all the historical information.

  32. alain -

    How are you determining the satellite delay is only 50 ms?

    The geosynchronous transmission propogation delay (i.e., time for signal to travel from earth to satellite and back to earth) is about 240 ms?

    So even if there was zero propogation delay in getting the data to the satellite uplink, your minimum delay should be just under 1/4 second.
  33. nitro -

    DSL isn't ubiquitous throughout all of the Chicago area. Seems SBC Ameritech was dragging their feet for a long time on suburban deployment while fighting in court about third party DSL providers getting access to their digital line equipment without at least reimbursing Ameritech for the cost of the line interface card hardware. They didn't want to have to potentially open their premises indiscriminately to every fly by night DSL reseller.

    That said, DSL is available by me but it's only 128K right now and it costs about the same as my existing ISDN so it's not worth it to me to go through the changeover until they delivery 384K+ speeds.
