Now, up to this point, I didn’t stumble too badly while putting all this together because Tradestation provides an enormous amount of support and hand-holding while you learn how to integrate the various tools during this phase. Everything that I personally learned through this trial was learned through the vast video tutorial library that they offered combined with a very user-friendly PM interface.
After the strategies and management rules had been selected and the inputs for each had been decided upon, I hit the Add Symbols, click the Tradestation Symbols List, select the Dow Jones Composite and the stocks load up automatically into the Portfolio I have created.
While in the same section, I hit the Interval Settings button to select the timeframe for the test and chose “Daily.”
I then went back and named my Portfolio and added the strategies above into the Portfolio as a Strategy Group. You can keep adding strategies or Strategy Groups to your Portfolio if you choose, but I did not during this initial run. However, by doing so, you can test a variety of strategy combinations and Strategy Groups in a Portfolio to test performance under a variety of different scenarios.
Once this phase is completed, you have the option of selecting the Portfolio Settings button and selecting a Constraint for the test. A Constraint is an overriding rule for the entire group of strategies that that make up your portfolio that would abort any trade signal or position that you have if that Constraint is violated. That could be anything from having no more than 30 positions at a time, a 20% overall drawdown, selling positions that have been open a certain amount of time or anything at all that you want to test.
For my test, I selected a maximum position of 30.
Finally, I was ready for to run my backtest and clicked the Portfolio Backtest button at the upper right-hand portion of the screen. A window will appear that will ask you to set the time frame, your portfolio size and the type of backtest you want – Standard, Optimization and Walk Forward.
To keep it simple, I selected a test over the last year with a $100,000 portfolio and a Standard backtest, and then hit the Analysis button to begin the backtest.
A Global Report pulled up, giving me my test results based on my inputs.
So far, the initial tests look promising with a 23.53% gain, but PM allows me to drill down and get a blow-by-blow account of each trade down to each symbol if I choose. Some stocks were obviously high performers with others offering a mixed bag of results. Now, I am thinking of how to filter out the low performing stocks with current settings or how to optimize the right position size strategy to compensate.
But, that is how the elegant power and flexibility of Portfolio Maestro quickly helps you to determine what works, and what doesn't, at the touch of a button. In addition, you receive a tremendous degree of support and education by an organization that continues to raise the bar in offering tools and support to help you succeed.
