Large volume does not rise but falls = Large capital is offloading (short on rebound)
Logic:
A truly strong upward trend must be accompanied by "volume and price rising together".
However, if a large volume is released but prices do not rise → it is mostly the main force distributing shares.
Action:
When a volume far greater than the previous 50 K lines appears
Price spikes but closes with a long upper shadow/candle
Short at the 0.382~0.5 position on rebound
Stop loss placed above the high point of the large volume K
