The siren's trend rectangle adjustment moves upward stage by stage, which is quite healthy. The bottom breaks from 35-42 to become 42-52, and then breaks from 52 to become 52-70. Each interval fluctuates for a period of time before breaking through, and the next breakthrough after 70 is estimated to become 70-100. 100 is just enough to double and withdraw the principal, while the remainder is left to accelerate the upward slope when it rises, perfect. #siren
