Understanding the myfxbook ratios with my systems

Hey guys,

I have two EA’s here that i have been working on. I have them both on myfxbook and noticed there are many ratios that i would benefit from knowing. Ratios such as sharpe ratio, Z score probability, AHPR, GHPR. I think i know what expectancy is though. I know no one prolly wants to type it out so is there a resource that someone may be able to point me to? How important are these ratios and which ones should i really be paying attention to?

Thanks
