The previous 'bubbles' ended when the price was at exactly +0.47 log units above trend.
I'd advice selling between +0.4 and +0.45 log units above trend, depending on how much risk/reward you like to see.
The lowest points between the tops has been mostly -0.45 or so below trend. So that would be a good point to rebuy.
What the price is exactly depends on what time we are at, as the log price increases every day.
If the bubble hits when I think it will hit, rptiela is spot on with his $5000 claim. But I'll make my decision on the log units mostly, and absolute price only secondarily, and of course my own TA charts.
Do you have a graph of this logtrend? I would like to see this. Thanks.
