On the fitness section of the builder, you add a "Worst Year Profit" analysis. It was a good idea, compliments! I would add a further analysis: a monthly analysis, because It would improve the analysis of the profit distribution, with the aim of minimize the stagnation in a useful way: we could add, below "Worst Year Profit", both in the fitness section and in the filtering section (see the attachment), a fitness/filter with the minimum number of month with a loss,and the maximum number of month with a loss. For example, min 0 month in loss and max 5 month in loss. So we could converge the building to a fitness with a minimum number of trading month losers. I and my friends we do this analysis manually, and this makes a fine result.
Again, we could analyze the maximum number of consecutive months in loss: this numbers is another powerful way to analyze the stagnation, but more hands-on: when we trade, it's a fine information to know how many consecutive months we can loss.
Thank you,
