Thank you for your kind words. You need to know what you want from an EA. The MT4/MT5 site, if you use MetaTrader, has a codebase section with free indicators and EAs with source code. You should pick something with a high star rating that trades on some simple rules like SMAs. Run that in Tester and display the Chart from tester to see the buying and selling decisions. Only through extensive testing on different periods (and that's fun by the way) can you evaluate reliability. I would stick with one currency pair only. But be prepared to spend a fair time doing this. I hope that helps.
