The prediction for Huobi above was obtained by fitting a weighted least squares straight line to the last three True Slumber Points, namely the mean prices at February 15, 17, and 18, 19:00--19:59 UTC (rightmost three yellow dots in the chart below), and extrapolating that trend line for one more day. The prices are ~3961, ~3905, and ~3817, respectively; which extrapolate to ~3775 CNY.

The prediction for Bitstamp, as usual, is that for Huobi divided by the normal currency factor R = 6.12.
NOTE 1: Those predictions are conditional to Huobi's clients and their robots being all in bed by Feb/19 19:00 UTC. Otherwise the Method offers no prediction.
