BTC 15-minute short-term rally of 0.37%: Active buying surges in, combined with increased trading volume, driving the price upward

Between April 30, 2026, 05:30 and 05:45 (UTC), the BTC price fluctuated upward from 75,427.8 USDT to 75,744.6 USDT, achieving a 0.37% return within 15 minutes, with a price volatility of 0.42%. Trading volume during this period expanded compared to the previous period, market attention noticeably increased, and short-term abnormal movements occurred.

The main driving force behind this abnormal movement was active buying in the spot and derivatives markets. Taking a major mainstream trading platform as an example, the 5-minute trading volume during this period increased by approximately 18% compared to the previous period, from about 1,200 BTC to 1,420 BTC. Meanwhile, the open interest in mainstream contracts increased by about 1.2%, with net capital inflows indicating bullish traders actively adding positions. Order book data showed a slight increase in buy order volume, with sell orders actively executed slightly exceeding buy orders, confirming that active buying drove the price upward.

Additionally, the bullish sentiment in the derivatives market provided a supporting effect. Funding rates remained positive, indicating strong bullish positioning. The Put/Call ratio in the options market was about 0.48, with call options holding a higher proportion than put options, reflecting a generally bullish market structure. On-chain data remained stable, with active addresses maintained between 11.5 million and 11.9 million. Large BTC transfers were not concentrated during this period, and there were no major external macro or regulatory events driving the movement. The market abnormality was mainly driven by internal capital flows and sentiment changes.

Regarding risk warnings, attention should be paid to the risk of price pullback if trading volume expands but buying follow-up is insufficient. If large amounts of BTC flow into exchanges in the future, it could generate new selling pressure. Although leverage levels in the derivatives market are not extreme, a reversal in market sentiment could lead to forced liquidations of leveraged longs, further increasing volatility. It is recommended to monitor the sustainability of spot trading volume, large on-chain capital flows, and changes in derivatives funding rates to prevent short-term pullbacks.
