For two consecutive nights, there was a violent rally before the US market (last night's rally was more misleading because the US stocks surged, leading many to believe it was a real rise). After opening, within 1-3 hours, there was a rapid sell-off that set a new low. This kind of violent washout method is very cruel, as it first retraces upward at a nearly 1:1 ratio based on the previous day's decline, and then quickly gives back all the gains from the violent rebound at a ratio of 1.168, creating a new low. The traces of artificial control in this trend are very obvious; if one were to trade long or short using the usual close stop-loss method, they would be stopped out. Only those who hold short positions at highs can succeed in such a market. Generally, this kind of fluctuating situation is designed by the manipulators to maximize confusion, and then when the retail investors drown in uncertainty, they unwittingly create the conditions for greater pain.
