Hey! If you could add 10y option on summers ratio and, secondly, add a 20y option on every ratio, would be nice! I know most ETFs dont have 20y existance, but we could analyse the "classic ones" or maybe the index itself.

Hi, thank you for the feedback! We already have an item on our roadmap to add more lookback periods to all available tools, including the Summers ratio. I’ll make a note to include 20-year ratios as well for instruments with sufficient historical data.
