Do you buy at the bottom when you see a rebound? The footprint map gave a warning yesterday

Yesterday afternoon, AiCoin News reminded that although SKHYNIX and SNDK rebounded, active buying and open positions did not increase synchronously, and a reversal cannot be confirmed at this time. As a result, SKHYNIX and SNDK only experienced fluctuations and adjustments, and the rebound did not continue. The latest 15 minute footprint map shows: -SKHYNIX has continuously experienced negative Delta values such as -9.24K and -5.09K, and when it falls, the position increases, indicating the entry of new seller positions; -SNDK also showed consecutive negative Delta values of -3.84K, -4.24K, and -5.08K, with selling still taking the lead. The current opportunity focuses on when the selling pressure will dissipate: -SKHYNIX: Follow $920~$905. If the negative Delta shrinks and rebounds to $940, there may be a short-term opportunity for recovery; -SNDK: Follow $1010~$1000. If Delta amplification is positive and $1030 is recovered, follow $1050~$1070. The value of a footprint map is very direct: it determines when active selling weakens and when buying truly takes over. -Price increases, but Delta shrinks and holdings do not increase, often resulting in a weak rebound; -Negative Delta amplification accompanied by increased positions indicates that the seller is actively attacking. Open PRO and use the 'Footprint Chart' to match position changes to find reversal confirmation. Don't rush to buy at the bottom before selling has stopped.
