Dear Members,
Another useful feature of the Strategy Tester is the optimization function, which allows you to test a trading robot with different input parameters and find the optimal values. Optimizing complex robots can be a very time-consuming process, but it can be greatly shortened using genetic algorithms.
The optimization results can be viewed in 2D and 3D modes. In addition to the built-in visualization tools, there are also custom visualization methods available.
MetaTrader 5 provides extraordinarily powerful tools crafted for developers of trading robots.
To begin optimization, you must select the “Optimization” field in the tester setup tab and press the “Start” button. This will open two new tabs in the window: “Optimization Results” and “Optimization Graph”.
Note: This will only be applicable on the desktop app
Hope this information helps
