### Basics Of Options Trading Explained

In the book, Greenblatt describes a trading model that he developed. While I have not tested his model and therefore can't recommend an investment strategy that's based on it, the book is worth reading because it outlines how he developed a profitable and consistent model for trading.

Models give us an objective manner in which to trade. They help take some of the guesswork and subjectivity out of deciding when to buy and when to sell, *options trading models*. Just like chart formations provide technicians with trading models, a well-tested statistical model can provide a framework for successful trading as well. Thus, as you develop your investing knowledge, here is an eight-step overview of my investment modeling class.

Step 1. Develop *options trading models* Hypothesis Begin by outlining a theory which you may believe can lead to a profitable model. Pose the hypothesis on some sort of logical statement "If X then Y. In other words, comparing **options trading models** stock prices to consumer spending might work, while a comparison to pharmaceutical prescriptions makes no sense.

Step 2. Build a Database In order to prove or disprove your hypothesis, you need to accumulate data over a long period of time.

The data should be in some sort of time series so that if you need to compare *options trading models* to other data points, you can line up the many variables which you will be utilizing.

Remember, the more variables and the more data points which you use, the more significant your output will be from a statistical perspective.

You must make sure that the data is from a reliable source, such as a premium service like Bloomberg or Reuters, or a solid free services like Yahoo! Also, I suggest that the data is retrievable in some electronic and downloadable form.

Once you download the data, you will want to **options trading models** to make sure that there are no missing, incorrect or "corrupted" data points. For example, sometimes a holiday will show up as a data point which must be deleted.

Step 3, **options trading models**. Make Observations With the raw data that you have now aggregated and organized in a time series database, **options trading models**, you will now scroll through the data and make some observations on what you see, *options trading models*.

Wondering what you're looking for? Your goal here is to notice any significant changes in the "dependent variable" the "Y" in the "if X then Y" example above based on changes for one or more of the "independent variables" the "X" in the example above. This exercise is one of visual observation that seeks to achieve one of two objectives. First, you want to confirm -- in a subjective and non-quantifiable manner -- that your original hypothesis step one is directionally correct and worthy of additional analysis.

Second, you might detect a pattern or anomaly that was not part of your original hypothesis and could form the basis of a new or modified theory.

As an example, you might recognize that "down" Fridays may be followed by "up" Mondays. Step 4. Develop Calculations This is by far my favorite step in the process. I call it "torturing the data. This may take one of two forms: logical queries or "regression analysis, *options trading models*.

If you perform a regression, then it is important to determine that your output meets or exceeds many of the statistical tests or requirements that confirm the statistical soundness and significance of the output. Step 5. Define Your Trading Rule The calculations that you perform in step four will now dictate a set of trading rules that you can now "codify" or "systematize". To calculate this, you can use the lower Bollinger Band using a day moving average, 1.

Sell at either a loss after 20 days or on any day that the QQQQ closes higher than the entry point. Step 6. Back-Test With your trading rule, which was developed through observation and hypothesis, now comes the true test, which is to determine *options trading models* the rule -- if traded on a consistent basis -- can actually make money. You do that by simulating the trading rule "back in time," applying it to the historical data in your data base and calculating the gain or loss, which would have resulted from the rule - as you have stated it, without modification.

Step 7, **options trading models**. Does the Model Make Money? If the answer is yes, then move onto the next and final step. If the answer is no, then you can take one of two paths. First, you can go back to step three Make Observations and develop a modified trading rule. Or, you can alternatively, simply abandon the model and begin it anew when a new hypothesis is developed.

Step 8. Can the **Options trading models** Be Traded? When you have created a model, which on a back-tested basis can make money, there is one final step you need to take before "going live" it. Step eight is where the practical aspects of trading take over from the academic aspects of the model development, **options trading models**.

Here, *options trading models* need to insure that you can trade this model in the real world, *options trading models*. *Options trading models* example, if your model dictates the short sale of a stock or index, you must make sure that such or a stock or index can be borrowed see " How Short Selling Works ". Another example may be one where you buy Chinese stocks and short-sell Hong Kong stocks. This rule may be impractical if you do not have access to the Chinese "A shares" because of regulatory or legal reasons.

I will elaborate on each step in more detail in follow-up installments of The Finance Professor. In the meantime, formulate your own hypothesis and start to aggregate the necessary data required to develop your own **options trading models** model.
