The optimized systems are not completed traded strategies. They were designed to show how the optimization feature of the system tester could be used. A general idea for a system is presented but a time period or a critical level for a signal is represented by an optimization variable. Optimization then allows you to run the test multiple times to find which value works best over a given range of historical data.

Different securities will likely have different values. You will also get different values as you vary the range of data being tested. Over multiple tests on multiple securities, certain values should appear more frequently in the top 5-10 results. After analyzing the equity curves, number of trades, profit/loss values, and other details of the system test results, you would pick a value you want to use for actual trading. Then the experts and exploration can be made.

To make the other tools, you would copy the buy and sell formulas from the system tester and paste them into the expert adviser and/or the explorer. When you do so, you will have to replace the OPT variables with the values you decided to use after analyzing the system test reports.
