Here is the daily chart of gold 2.50% 2.09% and bitcoin -4.80% -4.83% . Notice my use of Aroon 1 (blue) 11 (brown). Notice the correlation with Bitcoin -4.80% -4.83% when brown Aroon hits 100. Have boxed in volatility to nearest Blue Aroon at 100. The Aroon is done using the Gold 2.50% 2.09% chart. I've superimposed the brown Aroon on bitcoin -4.80% for better clarity.
Note that move could also be short lived to just one day, or, none at all. 3rd March didn't work well at all. Looks quite good at catching bitcoin -4.80% at point of rebound. All ideas 50/50
