You will find a myriad of settings available here, check in the back testing and settings area. Earl and ^eagle^ both have some very successful settings however your mileage may vary based on your risk tolerance, account balance, and your trading experience.
If I could suggest one thing it would be to understand the charts before you attach an EA to them. By understanding how other traders react to chart patterns, moving averages, etc you put yourself in a position to be moving with the herd instead of trying to trade against it. Couple that with having an account that is not undercapitilized for your minimum lot size and that should give you at least a fighting chance in the market.
There is also a set of settings here referred to as SuperCharged which some of us have purchased. So far it has performed well for me and the logic behind it appears to be sound, however if you are new to forex, spend as much time as you can on demo accounts as most folks blow out their first several accounts (myself included) due to not knowing what they are doing.
