Basics Of Trading Systems

 

It seems that everywhere you look, you see advertisements for software promising accurate buy and sell signals and profits with every trade - all with minimal time and effort. Ads like these can make trading systems look like scams aimed at your pocketbook. Is this stereotype justified? Or can trading systems offer viable methods of trading?

This tutorial addresses these questions and defines what a trading system is, and what it takes to design and implement one. If you are thinking of adopting a trading system, this is the place to learn about the skills and resources you'll need to do it.

The next section starts our study off by defining what trading systems are, outlining their components and discussing their advantages and disadvantages.

So What Is A Trading System?
A trading system is simply a group of specific rules, or parameters, that determine entry and exit points for a given equity. These points, known as signals, are often marked on a chart in real time and prompt the immediate execution of a trade.

Here are some of the most common technical analysis tools used to construct the parameters of trading systems:

• Moving averages (MA)
• Stochastic
• Oscillators
• Relative strength
• Bollinger bands

Often, two or more of these forms of indicators will be combined in the creation of a rule. For example, the MA crossover system uses two moving average parameters, the long-term and the short-term, to create a rule: "buy when the short-term crosses above the long term, and sell when the opposite is true." In other cases, a rule uses only one indicator. For example, a system might have a rule that forbids any buying unless the relative strength is above a certain level. But it is a combination of all these kinds of rules that makes a trading system.
