COVID-19: Daily momentum

This indicator shows 14-days moving average of daily rate of change (momentum, acceleration), in other words:

- up trends means that virus accelerates at the rate displayed on the right scale
- consolidation/horizontal movement - virus spreads at constant rate
- down trend - virus looses momentum IMPORTANT: the virus STILL accelerates but at a lower rate

By default the graphic displays World vs. EU vs. US vs. Asia while individual countries are available in Settings.

- EU includes the following countries (DE, FR, IT, ES, CH), all with more than 10k confirmed cases and more than 1k new daily infections.
- Asia includes CH and KR

To use the indicator it is important to disconnect main chart from the right scale, on main chart click on More (the 3 dots) -> Pin to scale -> Select "No Scale".
