Turn on the logarithmic graph. Invert scale. Imagine this is shitcoin. Global_trend was broken for the second time (Aug 17, 2015 & Mar 9, 2020). Buy or sell? If you see such things on shitcoin, you buy, increasing your position as you approach the orange zone.
Forget the inverted chart. Go back to bitcoin. Observe the downtrend (price peaks are falling: 20k > 14k > 10k > 8k?). Think about the virus, global recession, crude oil's negative prices. Bitcoin is not a hedging asset.
Summary: slow short. Cancel and buy when the price returns to the global uptrend (descent below the orange line on the current chart).
