[ Plot legend ]

The data point for today May/10 was very good (S = 0.0018, W = 0.939) but again way off the assumed trend. We must abandon the previous trend, and assume a new straight-line trend fitted by weighted least squares to the last three points (the second one, May/09, having nearly zero weight). Namely, A + B*(d-d0), where (d-d0) is the number of days since May/08, A = 2743.57, B = +26.48.

The Bitstamp prediction, as usual, is the Huobi prediction divided by the currency conversion factor R, taken to be 6.19 CNY/USD. Its value was 6.17 today (May/10), and 6.21, 6.21, 6.16, 6.23, 6.18 on the previous good sample times.

Foiled again again by the treacherous Chinese:

Huobi's predicted price: 2739 CNY
Huobi's actual price (L+H)/2: 2796 CNY
Error: 57 CNY (~9 USD)

Bitstamp's predicted price: 441 USD
Bitstamp's actual price (L+H)/2: 453 USD
Error: 12 USD

NOTE: Evaluation of the Chinese Slumber Method coming soon. Prepare to laugh.

You are way off pretty much every time. What's making you posting predictions?
