Structure & Formations

Key support levels for ASTERUSDT today emerged at 1.180–1.182 and 1.162–1.164, where the price paused on several occasions. Resistance was visible at 1.210 and 1.220. A bearish engulfing pattern at 1.221–1.220 indicated strong bear pressure. Additionally, multiple doji candles appeared near 1.195–1.197, signaling indecision in the market after the initial sell-off.

Moving Averages

On the 15-minute chart, the 20-period moving average (SMA) remained above the 50-period, confirming the short-term downtrend. For the daily chart, the 50-day SMA was below the 200-day SMA, reinforcing a bearish bias over the longer term. The 100-day SMA was also below the 200-day line, supporting the bearish technical setup.

MACD & RSI

The MACD crossed into negative territory during the early morning sell-off, confirming bear momentum. RSI dipped below 30 in the late hours, suggesting ASTERUSDT may be oversold and could see a bounce. However, RSI remains within a bearish channel, and a retest of 1.180–1.182 is likely unless buyers step in.

Bollinger Bands expanded significantly today as volatility surged, especially during the 1.221–1.220 bearish engulfing move and the 1.192–1.177 late-night sell-off. Price closed just above the lower band, indicating the market remains in a low-risk consolidation phase. A retest of the 1.180–1.182 support area could trigger a short-term bounce within the Bollinger envelope.

Volume & Turnover

Volume spiked during the morning sell-off at 1.221–1.220 and again after midnight when ASTERUSDT dropped to 1.177. Turnover also surged during these periods, confirming bearish conviction. However, price failed to find strong support during the 1.177–1.180 range, suggesting buyers are not yet willing to step in aggressively.

Fibonacci Retracements

Applying Fibonacci retracement to the morning 1.206–1.221 swing and the overnight 1.221–1.177 move, 1.202 and 1.197 represent key retracement levels. On the 1.177–1.221 overnight move, 1.195–1.197 aligns with the 61.8% Fibonacci level, where price showed indecision multiple times. A break below 1.180 would target 1.162 and 1.158 as next potential support levels.

Backtest Hypothesis

A potential backtesting strategy could focus on identifying bearish engulfing patterns, such as the one seen at 1.221–1.220, and testing their predictive value over a 3-day holding period. The pattern emerged at a key resistance level and preceded a strong bearish continuation, suggesting it may be a valid entry trigger for short positions. Using ASTRUSDT or the correct pair for ASTER/USDT, one could backtest this strategy across multiple timeframes and exchanges from 2022-01-01 to 2025-10-20 to validate its performance and risk-reward profile.
