Before this latest surge for the top two cryptos, recent sudden drops followed a ban on cryptocurrency transactions and mining from China’s central bank, which declared all cryptocurrencies illegal in the country. After previously topping $52,000 in early September, Bitcoin’s price had dropped and struggled to get back over $50,000 until this month.
At each point information from neighbouring data is used. As the time series considered are finite, the areas at the start and end of the data (especially at higher period bands) will not have all the data required. One solution to make computation possible, chosen here, is to pad the time series with zeros where required. However, the zero padding will impact the reliability of the results. It is standard to use a cone of influence to represent this difference in reliability of results. Pale colours represent those areas outside the cone of influence with less reliable results (as seen on Fig 3). Higher period bands require more data for computation resulting in the cone shape.
