An Expert Adviser is the program that is based on some trading strategy, and can open and close the trades automatically.
To backtest the EAs that are already included into Forex Tester, navigate to the "Testing → Strategies list" menu. Or you can click on the "List of Strategies" button on the toolbar.
Make sure that the strategy execution is enabled. The "Enable / Disable strategy execution" button on the toolbar should be active. Another way to enable this feature is to navigate to the "Testing → Enable / Disable strategy execution" menu.
We will cover the topic of Expert Advisers on the "Awesome Expert Adviser" strategy example.
Forex Tester will open and close orders automatically due to the strategy rules that were programmed in the Expert Adviser.
To add a custom EA file that has a .dll extension, please navigate to the "File → Install → Install new strategy".
