A Million Dollar Reason Why Stock Trading Delays Must Be Fixed Fast

By Lance Jepsen

Delays in data center networks can now be detected that are as short as a millionth of a second. Computer programmers have created a clever software program that can save investment banks running automatic stock trading systems millions of dollars.

The work was presented on August 20th, 2009 at SIGCOMM. The computer programming method was created by a joint task collaboration between the University of California and Purdue University computer programmers.

This small programming code can detect delays as short as a millionth of a second in a router. The code will also detect packet loss as small and rare as one packet loss in a million. Every router in a data center can run this small code.

No new hardware is required. The team of computer programmers call their code the Lossy Difference Aggregator. The programming code has no speed penalty on the router in which it runs.

Online brokers houses and stock trading platforms will love this new technology. The reason is that if you can get into a trade faster than everyone else, their buy orders will push up your position. A delay of even 100 microseconds over an incoming stock data feed can cause your buy and sell orders to be behind that of competing brokerage houses.

Exchanges like the Nasdaq use very expensive custom hardware designed to track delays in the performance of routers at different key points within a data center network. But these hardware boxes are too expensive to be added to every router within a data center's network. Especially if that data center is running an automated stock trading system. By the time the I.T. Department detects a problem router, it usually costs the company 1 - 3 million dollars in delayed entry and exits on trades.

This approach will allow router vendors to add fine scale delay and loss tracking at every router for little if any cost. This will obsolete expensive external network monitoring boxes at every router.

The way a router's performance is measured now is that an external hardware device tracks when a packet arrives and when it leaves and then takes the difference of those times.

Instead of tracking the entry and exit times of all packets going through a router, this computer code randomly divides the incoming packets into groups and then calculates the entry and exit times of each group. As long as the number of losses is smaller than the number of groups, at least one group will give a good estimate.

Calculating the difference of the groups arrival and departure times and then dividing by the total number of messages gives a very accurate estimate of the average delay of a given router. This approach requires so little computer programming code that it really is about the same code as a simple counter.

A data center network that has this programming code built in to every router will be able to quickly pinpoint a faulty router that is adding an extra millionth of a second delay or that is losing one packet in ten million. - 23196

Winning In The Stock Market

By Sean Phelps

Professional traders kill amateur traders in the stock market with double top and bottom patterns. Do not be another victim. In fact, after reading this article you will be able to get the revenge you deserve.

Every rally in the stock market reaches a point where enough bulls look at it and say"I've made a lot of money, and I might make even more money, but Id rather take my profits off the table. Charts top out when enough bulls take their profits, while the money from new bulls is not enough to replace what was taken out.

Bulls who are still long are screaming mad, especially if they came in late. They feel trapped. Their profits are melting away and turning into losses. Should they hold or sell? If enough bulls decide the stock has overshot to the downside, theyll step in and buy. As the rally resumes, more bulls come in. Now prices approach the level of their old top, and thats where you can expect sell orders to hit the market.

Many battle scared traders who got caught in the previous decline take a blood oath to get out if the market gives them a second chance.

A mirror image of this situation occurs in the stock market at market bottoms. The market falls to a new low at which enough bears start taking profits by covering shorts and the market rallies. Once that rally stalls out and prices start sinking again, all eyes are on the previous low-will it hold? If bears are stronger than bulls, prices will break below the first low, and the downtrend will continue. If bears are weaker than bulls, the decline will stop near the old low, creating a double bottom. Technical indicators help decipher which of the two is more likely to happen.

Whenever you see a stock climb to its previous high, the first question in your mind should be will the stock climb to a new high or form a double top and head back down. Technical indicators like the RSI, MACD, and volume are very helpful in answering this question.

When a stock rises to its previous peak, a double top is most likely to form when the volume, MACD, RSI, and stochastics are falling.

A double bottom is most likely to form if the MACD and volume start rising when the stock hits its previous low. - 23196

Tax Liens An Overview

By Steve Jonas

The tax portion of the term typically refers to unpaid property taxes. The dictionary definition of lien is:

"The legal claim of one person upon the property of another person to secure the payment of a debt or the satisfaction of an obligation."

Tax lien uses the property of an individual as the collateral of a tax-related debt owed to another party as a security of the settlement. While the debt is initially owed to the government which places the taxes, after a certain period of time passes, these government agencies will then auction the unpaid debts in order to compensate their own expenses promptly, and to open new opportunity for savvy investors.

Tax liens are a product of the local governments and are not only 100% legal, but the interests of the investors are protected by each state they purchase from. To their gain, State governments will organize the entire tax lien procedure.

Also, buying tax lien certificates is completely safe and open because the investors are actually true to their words and do pay the required taxes imposed. These certificates can be bought at tax sales where a county or municipal official is conducting it.

If everything else has been settled, the lien will then be handed to the investor from the government. If this is already complete, the investor will now have the right to collect all of the stated interest that has been made by the government. The usual interest stated in the lien is between 8% and 25% per year.

To be fair, the property owner is given a time frame wherein he/she should pay a stated amount of the tax, interest and other related fees. But if the owner fails to pay on the given time, the investor will now have the right to foreclose the property because of the lien.

Tax lien is a highly attractive investment. Since a thousand dollars or paying any brokerage fees is out of the question, tax lien certificates are very impressive investment.

Tax lien certificate is an investment that requires your attention and time. If it happens that you have made good purchases and have research the properties that are attached to the tax liens, then you would most likely be happier to acquire a property through foreclosure. However, the list of properties that you will usually have before the sale from the tax office is minimal only, in which it would only tell less about the property. Most often than not, you'll only acquire the tax ID, amount owed and owner of record.

In addition to this, when making your first investment, it is highly advisable that you have a copy of the assessment information first and then locate the property. If you already have the address, it does not hurt if you pay a visit to the property and see for yourself if the assessment is updated. Also, through visiting, you will have an idea whether the property costs more that what is owed for back taxes. Always bear in mind that there is a possibility, if it does not redeem, that you will have to pay the taxes of this property throughout the period of redemption before you can actually foreclose on it and apply for a deed.

Foreclosing on tax lien properties will really certify you a profit that is usually several times your initial investment. - 23196
