And to make it worse, i have also added a BETI indicator to Tradingview.

Hah, that's cool

However, it seems to be a it off: For the 2013 bubble top, I get a BETI of ~2.9, when it should be around 1.5?
Hm, that's strange.. I have just used the formula in the wolframalpha-link which is used to lately calculate the beti. I'm trying to check whether the wolframalpha-formula is not the same as what was used for the first beti-charts, but I'm still struggling with WA.
editIn the past very different parameters have been used for BETI.
