This trading expert (EA) can also save the necessary settings to a separate file. This is particularly useful if you have open positions and need to restart your operating system — for example, to install new updates. To ensure that important settings are preserved, simply close the trading terminal before restarting. A separate file containing the important settings will then be created. Once the updates have been installed, simply open the terminal and all settings will be reloaded. This ensures that full functionality is retained for subsequent automated trading.
