// Expert Advisors: Visualization of Optimization Results in Real Time

MetaTrader 5 Strategy Tester allows to get statistical parameters of a trading system after each testing pass.

Statistical parameters can be obtained using TesterStatistics() function, which is called inside OnTester() and OnDeinit() functions.

With the introduction of functions for working with optimization results (FrameFirst(), FrameFilter(), FrameNext(), FrameInputs() and FrameAdd()), traders are now able to perform visual optimization. The necessary data now can be processed and displayed right during an Expert Advisor optimization or a mathematical problem solving.

We will consider the details of the example of visualization of an Expert Advisor testing results during the optimization described in the article "Visualize a Strategy in the MetaTrader 5 Tester".
