what is In-Sample and Out-Sample? and how *Yearly Return/MaxDD is being calculated?
Yearly RoMaD takes yearly returns and divides it by yearly max drawdown. More on RoMaD at https://www.investopedia.com/terms/r/return-over-maximum-drawdown-romad.asp#:~:text=Return%20over%20maximum%20drawdown%20(RoMaD)%20is%20a%20risk%2Dadjusted,portfolio%20return%20%C3%B7%20maximum%20drawdown
In Sample and Out Sample, divides your backtest result into two periods and shows statistics on those two periods separately. Idea being, you can optimize your parameters for in sample period, and validate your hypothesis on out sample period. This should prevent you from pitfalls of curve fitting.
