If you will have a look at the chart after you have built your strategy you will see all of the entries and exits marked for you....... and as you move your cursor you will see, on the right hand side of the chart. the account balance changing and the signals....

and all of this is done immediately you adjust the indicators.

There is a slider on the bottom of the chart so that you can scroll to the start of the data and analyze effectively every entry and exit and observe the account balance changing.
