The simulation report appears when you backtest or optimize a trading system. In the top panel, it displays a table, where each row represents a trading system backtest result. The table contains the following columns: Name, Annual return, Maximum drawdown, Sharpe ratio, Percent of winner trades and optimizable fields.

In this post, we will show you how to create a custom metric.


- Select "Analysis" then "Simulator"
- Click on "Create a metric" (If the menu is not extended then click on the "+" icon)
- Click on "Help" to get information about the methods and variables available in the metric script tool
- Type the following script:

if(AnnualReturn > 10 && SharpeRatio > 1 && SortinoRatio > 1.5)
  Fitness = 1;

Our metric returns one if the backtested strategy meets the following criteria: Annual return higher than 10%, Sharpe ratio higher than 1 and Sortino ratio higher than 1.5

- Click on "Save Formula", type a name for the metric (Example: MyMetric) then click on "Save Item"
- Close the form then click on "Metrics" in the simulator manager
- Check "MyMetric" then click on "OK"
- Select a trading system then click on "Simulate" or "Optimize"

The report tool will display a new column called "MyMetric".

Note that you can also add a metric by using the money management tool.

Trading financial instruments, including foreign exchange on margin, carries a high level of risk and is not suitable for all investors. The high degree of leverage can work against you as well as for you. Before deciding to invest in financial instruments or foreign exchange you should carefully consider your investment objectives, level of experience, and risk appetite. The possibility exists that you could sustain a loss of some or all of your initial investment and therefore you should not invest money that you cannot afford to lose. You should be aware of all the risks associated with trading and seek advice from an independent financial advisor if you have any doubts.
