Stock trading systems are essential for profiting in the stock market.  If you try to invest without having your trading systems in place you are bound to have a rough go.  There are so many pitfalls that you could fall victim to if you don't have a nice structured trading plan.  Investing money in the stock market causes many people to get emotionally attached to whatever stock they happened to buy.  The number one key to a stock trading system is to detach yourself from each individual trade.  If you ask anyone who has ever played the stock market they will tell you that you can't pick winners every time.  Even the very best stock analysts will be wrong a good percentage of the time.  The key to making money in the stock market is how you react when a trade doesn't go your way. 

There are countless stock trading systems out there, however most of them will fall in to one of two categories: investing systems or short term trading systems.  Any of the good stock trading systems will have one thing in common, they will identify high probability entry points for a stock.  What that means is that the system will give you a signal to buy a stock when it has a good chance of going up.  This is the basic, bare bones idea of trading systems.  The difference between the two types of stock trading systems is the length of time you will be holding a position.  In an investment style system, you will be looking at longer term trends and the fundamental finances of a company to determine an entry point.  These investments can range in duration from a few months to many years.  This is commonly referred to as the “buy and hold” investment strategy.  This is the classic way to invest in the stock market.  With the advent of online trading brokers with discounted commission rates, more people have been looking into short term stock trading systems.  It is easier than ever to open your own account and make trades without ever having to call a stock broker to help you execute your trades.  This new convenience has required your average investor to digest a whole new level of investment knowledge.  If you are going to dabble in short term trading, it is imperative that you follow a good stock trading system.  These short term trades can be anywhere from a few minutes to a few weeks in duration.  The specifics vary between the different trading systems.  There are many different sources offering their own specific trading system.  If you have never traded stocks using a concise plan of attack, I would suggest taking a look at a few of the systems people have developed.  You have to make a decision about how much time you want to spend on a daily basis engaged in your investment strategy.  Many of the short term trading systems will require your attention on a daily basis, maybe even more often.  Some companies offer automated stock trading systems for a fee.  This is something to consider if you don't have the time to delve into the research every day.  If you are going to purchase a trading system, or want to develop one on your own; it would be a good idea to look at what makes a system a good one.

• Identify entry and exit points

This is a must.  Without having these two points set before you enter a trade you really don't have a stock trading system.  The idea is to find a price where it is more likely for the stock to go up than to go down.  Once you have established that entry point you should have a predetermined point where you will sell the stock.  This could be at a loss, or after a certain amount of profit.  The key is to have these targets mapped out before the trade even starts.

• Sound money management principles

All the good stock trading systems incorporate money management into the plan.  You should be trading with a certain percentage of you available funds at any given time.  If you were to use all of your money to buy one single stock, that would be an example of bad money management.

• Eliminate the emotion

The previous two characteristics both help with eliminating your emotion from your trading.  The single biggest mistake an investor can make is to get too attached to a certain stock.  If you make a stock purchase based on your identified entry point and it happens to go against you, sell the stock and look for the next trade.  Everyone has losing trades, but the people who cut their losses come out much further ahead. 

If you are looking to become a bit more disciplined in your investing, I would advise looking at some of the different stock trading systems that are out there.  After you have an idea of what different systems are available, you can go about developing your own plan of attack.
