The Forex Robotron EA settings are externally available which means that you can adjust them via the inputs window when you attach this robot to the charts in your trading platform. You can always just use the default settings provided by the developer that have already been optimised but you should always check to make sure that the lot or risk size is set to a suitable level for your risk preferences as every trader is different in that respect.
For those of you who have the experience, you are free to experiment with the Forex Robotron EA settings to develop your own bespoke set files. I would use the MT4 strategy tester to backtest the software across different currency pairs and chart timeframes to discover unique combination of settings that match my trading style and goals. There are recommend currency pairs to use but that does not mean you cannot run it on other financial instruments. However, if you do wish to experiment with the Forex Robotron software, then you may want to do so on a demo account to begin with and see how things go.
