NB The grey textbox in my chart says that price dropped from ATH to 26MA line in 2 days - is a typo, should be 3 days.
Close up of price retrace before larger correction:
At the moment BTC is still in uptrend so I'm until the 26MA is broken. I do feel the segwit fork could be overextending BTC this time though, so it might drop down the the 26MA line in less than 3 days (and I would not be surprised if it would take less than a day this time).
Only notable difference is that in these earlier BTC cycles, the price didn't go back up much after it broke below the line.
