BTC buyer takes position, seller takes pricing power At 11:46 today, OKX BTC/USDT perpetual opened 43800 long positions with a value of 27.5872 million US dollars, with a unit price of $63000, making it the largest major trading deal for the cryptocurrency pair in recent times. But when this purchase was made, there was a cumulative net outflow of 110400 active funds. According to the footprint chart signal, the 15 minute K-line Delta that broke through $63000 expanded to -98.45K: active sell orders continued to push towards limit buy orders and successfully pushed the price down. This is the reason why it failed to form support. Limit buying only provides passive liquidity; Only when the selling pressure is taken over and the price no longer sets a new low, can it be considered truly absorbed. After this transaction, BTC not only failed to recover $63000, but even if positive Delta values such as+11.53K,+14.87K, and+11.98K appeared in the future, the rebound height was still limited, and it was subsequently pushed back by active sell orders such as -27.42K and -18.65K. Active buying occurred, but did not result in an upward price push, indicating that the price chasing buying was absorbed by the supply from above, and the bulls were unable to regain pricing power. This is the same as the Binance spot order tracked on August 1st: Binance spot main traded 1235 BTC at $64000, worth $79.04 million. Based on current prices, if the position has not been sold or hedged, the floating loss has increased from $1.32 million at the time to $1.59 million. OKX's order of over $63000, estimated linearly based on nominal scale, currently has a floating loss of approximately $126000. Two large orders were executed at $64000 and $63000 respectively, but neither of them changed the downward structure. They not only leave behind 'support', but also two potential cost zones. Next, let's focus on: -$63000: The first repair line. Price recovery is required, and at the same time, positive Delta amplification and active fund conversion → active buying has an advantage; -$62110: Peak support for chips in the past month. If the negative Delta shrinks during testing and the price no longer sets a new low, it is evidence that the selling pressure has been absorbed. Big buying can buy away selling pressure, but cannot directly buy trends. The determination of whether it is supported or not is never based on the transaction amount, but on whether the price still falls after the transaction.
