Structure & Formations

The price action over the last 24 hours revealed a strong support zone forming at $0.00424, with price bouncing off it several times after a downward correction. A small bearish engulfing pattern appeared around 23:00 ET, indicating sellers taking control. Additionally, a doji at 03:30 ET suggested indecision and potential reversal. The resistance level at $0.00426 was tested multiple times but held firm, preventing a breakout.

Moving Averages & Momentum

On the 15-minute chart, the 20-period moving average crossed below the 50-period line in the early hours of the morning, forming a bearish crossover. The 50-period MA at $0.00425 acted as a key level, preventing further upward movement. On the daily chart, the 50-period MA currently sits above the 200-period MA, signaling a slightly bearish trend. The MACD remained negative throughout the session, reinforcing bearish momentum, while RSI fell below 30 in the early morning, indicating potential oversold conditions.

Bollinger Bands & Volatility

Bollinger Bands constricted between 01:00 and 02:00 ET, signaling a period of low volatility and hinting at a potential breakout. By 03:45 ET, the bands expanded again as volatility increased. Price traded below the lower band for a brief period, suggesting a test of the support zone. The band width at the end of the session indicates elevated volatility, which could point to increased trading interest.

Volume & Turnover Analysis

Volume was concentrated in the first half of the session, peaking around 23:00 ET when price dropped below $0.00426. Notional turnover spiked to $0.28 at that time, suggesting significant selling pressure. However, after 05:00 ET, volume declined significantly, despite a further pullback in price. This divergence between volume and price could indicate a lack of conviction in the current bearish trend.

Fibonacci Retracements

Applying Fibonacci levels to the most recent swing high ($0.00428) and swing low ($0.00424) identified key retracement levels at $0.00426 (38.2%) and $0.00425 (61.8%). Price found support at $0.00424 in the early morning and again at 06:30 ET, aligning closely with the 61.8% level. This suggests that this area is gaining structural importance and could serve as a critical level in the near term.

Backtest Hypothesis

Given the observed bearish momentum and key support levels, a potential strategy could involve shorting ARBBTC after price breaks below $0.00424 with confirmation by volume. A stop-loss above the 61.8% Fibonacci level at $0.00426 and a take-profit target at the nearest downtrend level could be applied. This aligns with the observed RSI divergence and bearish engulfing patterns. A backtest of this strategy using the last 30 days of 15-minute data could help validate its viability under similar volatility conditions.
