Subj: System Testing Groups of Stocks? Has anyone figured out how to do test a system against a group of stocks? I can now create a "system" and test it against one stock at at time and get back a statistical summary of the buy/sell transactions, etc. It would seem that I should be able to turn the computer loose now to test the system against a group of stocks I've defined and see how it performs against the group. This I have not figured out how to do. Suggestions? Thanks. Bill

TT: Just got in and saw your note, so this is a bit off the top of my head. Two quick methods come to mind. #1 Create two charts, one daily and one weekly. Display the two side by side (or top and bottom) on one screen by going to the window drop down menu and selecting either tile horizontal (or tile vertical). This will display the two charts at the same time, but with different time frames. If you wish to apply the indicators to other securities, you can save the two charts as a group. To change to another security, you will have to change each chart individually - at least I've not found a way to change both charts simultaneously. #2 Create your daily indicator and then add the approximate weekly indicator by dividing the periods by 5. Alternatively, create a weekly chart with the indicator and and then multiply the periods by five. Not always exact as this wouldn't compensate for the occasional four trading day weeks but I think it's close enough. I often use a 13 week / 65 day period for certain indicators. Works out to just about a quarter, and serves as a fib number as well. Not sure what you mean about integrating into a system test. However method #2 would allow you to combine day and week periods in a system test's formulae. Can you give an example of what your trying to test for? Peace and Justice --- Patrick
