Re: BETI: Bitcoin Exponential Trend Index and technical analysis

Yes, thank you jl2012 for one of the very best and helpful (long-term context providing) threads on this board.

You used to update a graph (as per OP) that, apart from price and regression line, showed the expected price of any day based on the best regression line up to that day. I thought that interesting. If you get the time and inclination, could you perhaps update it again at some point?

TIA

Please see last page. This chart doesn't need to update every day as it makes very small difference

Thanks - I was thinking of your "series2" red line which doesn't seem to have been updated for over three years. I appreciate that it barely murmurs on a daily or even monthly basis, but it does record the changes in the implied angle or 'aim' of the best-fit line and with it the acreage of our fantasy islands.

For an example (of the fun to be had) I still have a bookmark (which I think is from your work, a then best-fit that now needs the crotch taking in a bit):

Oh how I dreamed of today back then!

You want this? I don't think it's very useful but anyway

Thanks for putting it together in any case.

I like it as a record of how the line of best fit has changed. As you say, it doesn't change much and it hardly ever points down, and clearly as time passes it will tend to hug the best fit ever more closely - but in retrospect its tangent can be seen as a loose proxy for the market's 'exuberance', irrational or otherwise. Thanks again for your work.
