evaluate (PERFORMANCE* perf )
User-supplied function that is called at the end of a [Test] run, or when [Result] is clicked, or in [Trade] mode when the status page is updated. Can be used for analyzing the performance or storing it for further evaluation in a user specified way.
perf - optional pointer to a PERFORMANCE struct containing the result of the test; defined in include\trading.h.
User-supplied function that is called at the end of a simulation or session. Can
be used to free memory or release other allocated
- All trade statistics and strategy statistics are available
in the evaluate function. The ...Long/...Short statistics parameters are for the last selected asset and algo.
- The print (TO_REPORT, ...) function can be used for printing user-specific data to the performance report.
- In [Train] mode the objective function is called at the end of every simulation. The evaluate function is called only in the test run after training when the TESTNOW flag is set.
