Plot legendToday's data point was fair, (S = 0.0 035 W = 0.782) and, like the previous one, totally off the trend of Apr/16--18. Whatever external causes sustained that trend must have ceased, so it is appropriate to start a new trend, the straight line defined by the last two points. Namely, A + B*(d-d0), where d-d0 is the number of days since Apr/19, A = 3153 and B = -28.
The Bitstamp prediction, as usual, is the Huobi prediction divided by the currency conversion factor R, which was assumed to be 6.24 CNY/USD. It was 6.25, 6.26, 6.18, 6.21, 6.23 at the last five Slumber Times.
