Structure and Candlestick Patterns

The 24-hour chart exhibited a strong bearish trend early on, with multiple large bearish bodies and a long-range candle during the 10:45 PM–11:00 AM ET window that marked the low of 11,300 IDR. Following this, a bullish reversal candle formed after a period of consolidation, signaling short-term support hold and increased buyer aggression. No strong reversal patterns such as hammers or engulfing patterns emerged before the final rally, but the long-wick candle at 10:45 AM ET suggested a critical support level was being tested.

Volatility and Bollinger Band Dynamics

Bollinger Band contraction was observed during the early morning hours, indicating a period of low volatility and indecision. However, the final candle before the 12:00 ET close broke above the upper band, suggesting increased volatility and a potential short-term breakout. The price spent a significant portion of the day within the band, but the late rally pushed it above, confirming a shift in momentum.

Momentum and Indicators

RSI remained below 30 for most of the session, indicating strong oversold conditions that could support a bounce. MACD showed a bearish crossover early in the day, but the histogram began to narrow as the rally progressed, suggesting weakening bearish momentum. The 20-period moving average on the 5-minute chart acted as dynamic support during the final push, further reinforcing the potential for a near-term reversal.

Volume and Turnover

Volume remained low early in the session, but spiked during the final hour, with the 10:45 AM ET candle alone contributing 7,492 ASTER (74.9% of total volume). This spike coincided with the most significant price movement and suggested increased buyer participation. Turnover closely followed the volume pattern, with the bulk of notional value exchanged during the same period. The divergence between early bearish price action and late bullish volume implies a potential shift in market sentiment.

Looking ahead, Aster/Rupiah may continue to consolidate around the 11,800–11,850 IDR range in the next 24 hours if buyers maintain control. However, a retest of the 11,300–11,350 IDR support level could trigger renewed selling pressure. Investors should remain cautious and monitor volume behavior for confirmation of trend direction.
