When should this short position be taken? Carefully look at the chart. After the 15-minute mutual death cross confirmation, when it drops down, it will rise again, and then breaking the previous high with a spike is the best short position time, meaning institutions will induce a wave of longs! So, enter with 1 layer of position when the 15-minute mutual death cross is confirmed, add 3 layers of position when a new spike is formed, and then set a stop loss 10 points above the new spike's high!
