I spent some time looking into the fundamental data and attached my notebook for convenience. 

However, I failed to retrieve any of the more useful ValuationRatios 3Yr, 5Yr, etc. Wondering if these calculated ratios are available at all.

Anyhow, I am able to calculate any ratio in a notebook but I did not find any sample which shows me how I can retrieve the history of Fundamentals in my strategy. 

All samples only show how to filter on the latest value. That does not do much for a proper long-term alpha. Sustainable growth and improvements in the income statement are relevant to choose the proper investment.

Maybe someone knows better?
