Today's data point was not bad (S = 0.0049 W = 0.614), and above the previous trend line, but not by much (by 37 CNY). It seems still valid to use a straight-line trend, fitted by weighted least squares to the last six points, Apr/19--24. Namely, A + B*(d-d0), where d-d0 is the number of days since Apr/19, A = 3138.67 and B = -12.01.
(The older data points should have their weights reduced when fitting the trend, but the effect on the prediction would have been small.)
The Bitstamp prediction, as usual, is the Huobi prediction divided by the currency conversion factor R, which was assumed to be 6.29 CNY/USD. It was 6.30, 6.28, 6.34, 6.27, 6.25, 6.26 at the last five Slumber Times.
