ASTER current quote is 0.6938 USDT, and the 15-minute chart releases interesting technical signals.

How is the market rhythm? Low volatility has been the main theme in recent days, with moving average fluctuations only at 0.31%, which looks surprisingly calm. However, a closer look at the candlesticks shows three consecutive bearish candles dropping sharply, especially the 8th one, with a decline of 0.46% and a real body ratio as high as 88.9%, indicating that the bears are gathering strength. This is a hallmark move of selling pressure release.

But there is a turning point here — the real bodies of the following two bearish candles have significantly shrunk, at only 6.5% and 12.5% respectively. More importantly, the 9th candlestick shows a sudden increase in volume, while the price hardly moves, a typical "volume expansion with stagnation" phenomenon. This often signals that the downward momentum is waning, and a short-term rebound may be brewing.

From a technical perspective, the combination of oversold conditions followed by a convergence of decline and volume expansion with stagnation is a precursor to a rebound.

**Trading idea**: The opportunity for a light long position has already appeared. Enter within the range of 0.6910-0.6935, which is relatively low. Set stop-loss below 0.6880; if it breaks the previous low, cut losses. The upper target is the previous resistance zone at 0.7020-0.7050.

Considering the low volatility and limited profit space, quick in-and-out trades are suitable. The key is to strictly execute stop-losses to prevent small losses from turning into larger ones. Also, don’t forget to keep an eye on Bitcoin’s overall market trend; if the market weakens, the entire logic becomes invalid. If volume breaks through 0.7050, there is still potential for a rebound.
