Computer-to-computer interface. The term is used usually by IT departments in brokerages to denote their electronic interface. It's usually a proprietary protocol. But a lot of firms (usually buy-side) use the FIX protocol.

I have a Matrox Quad card and I sometimes play Unreal Tournament on it. It's definately a slower card for games but it's usable. But I'm not a serious gamer.

If you run into any problems, check to see if you are doing any type of packet filtering. You will have to allow both TCP and UDP access to port 4000 to the following ip addresses: 208.245.107.3, 208.245.107.4, 208.245.107.5 .

Just curious. Is liability an issue with a pro firm? One of the advantages that using a firm like Bright, etc., is that they offer use of the firms capital, something like 10-1, I've read. But to circumvent RegT, the common thing to do is for the firm to organize as an LLC. LLC's can avoid...

Are you certain about this. The new rules affect margin accounts only not cash accounts. As far as I can tell, there is no SEC rule that prohibits daytrading in a cash account. dlinke brings up an interesting point regarding freeriding. NASD rules do prohibit freeriding and allows a brokerage...

It occurs to me that once this rule goes into effect a lot of daytraders that use margin will start to begin to trade lower priced stocks because of the lack of margin. I wonder if anyone at the SEC stopped to think of the ramifications of the new margin rules. I bet it increases volatility...

I was wondering why brokerages would want the new margin requirements. Doesn't it eliminate a large portion of their business. The only reason that I can think of why a brokerage would want the higher balance is to allow them to increase revenue from the normal 12b1 fees on the balance to offset...

Hmmm.... Seems like an odd thing to do since a satellite feed is slower than an ISDN line. More bandwidth but much slower.

Predictor, make sure that you are using the video hardware to draw the mouse pointer and not a software mouse pointer. If you have the latest Matrox drivers installed. 1) Go to Display Properties by right-click on your desktop. 2) Select the Options tab. 3) Under performance, select...

I'm in the process of getting rid of my Tradestation Pro system because of it's poor data feed so I've been trying out eSignal with Ensign. I like the eSignal feed a lot. I also downloaded the Ensign software to trial but I have to admit that I found it a bit clunky to use. It seems adequate...

The upgrade doesn't seem to be helping at all. I'm still seeing lagging quotes. Like Babak, I am getting disconnected all the time.

I'm under the impression that Windows on Wallstreet is now a business unit of Tradestation (Omega Research). I've also been told that the Windows on Wallstreet data feed is the same as used by Tradestation Pro. I've had Tradestation Pro for three months and it is the worst data feed I've...

Hmmm.... I just received an email from Tradestation that they will be upgrading their system this weekend to allow direct access trading and faster service. I just signed up a trial with eSignal because of the problems with the data lags in Tradestation and I was planning on cancelling my...

At the risk of sounding dumb :-) What's a FCM? Also a quick question regarding shorting with InteractiveBrokers. When shorting a stock, is it still possible to route the sale to an ECN? My current broker can only offer direct access for long positions.

I have Matrox Quad and in w2k it works decent. I don't really care for the support that Matrox provides. They don't seem to be as interested in the multi-monitor market as Appain is. In retrospec, I do sometimes wish that I had bought an Appain instead.

Mr. Lemandri is obviously misinformed. This quote is from a September 16, 1999 testimony of Arthur Levitt, Chairman of the SEC before the Senate Permanent Subcommittee on Investigations Committee on Governmental Affairs, Concerning Day Trading. (goodness, why do senate subcommittes have...

I use Tradestation Pro's tick charts as a supplement to tape reading. I'm primarily a tape reader once I get a technical indication for an entry. I usually read the tape with a plain-old time&sales window but tick charts are helpful for me because give me a visual sense of momentum. I...

Thank you very much for validating my post. I have been wasting too much time trying to figure out what was wrong with my system and/or ISP. It sounds like I need to find another product.

I've been using Tradestation Pro for a few months. And I find it extremely unrealiable. It seems to be getting worse over the last few weeks. Is anyone else having problems with their data feed?

Pooling analog modems is not a good idea. When you pool modems, you are increasing the amount of bandwidth that is available to you. However, in trading the important factor is latency, not bandwidth. Latency is the amount of time in measured in miliseconds that it takes a small data packet...
