Structure & Formations

The ETHFIUSDT pair displayed a strong bullish reversal from a 1.544 support level, confirming its significance. A bullish engulfing pattern formed at 1.570, followed by a strong rally into 1.670, indicating renewed buying interest. A 1.677 high was challenged but not decisively broken, suggesting the potential for consolidation or a pullback into the 1.62–1.63 zone. A doji formed at 1.605, hinting at indecision and possible short-term profit-taking.

Moving Averages

On the 15-minute chart, price closed above both 20-period and 50-period moving averages, reinforcing the bullish trend. Daily moving averages (50/100/200) showed a multi-day upward bias, with the 50-period line currently at 1.63, supporting the idea that further gains may be likely as long as price remains above this level.

MACD & RSI

The MACD line crossed above the signal line in the afternoon, confirming positive momentum. The histogram showed increasing bullish divergence, especially between 21:00 and 05:00 ET. RSI reached a 75 level, signaling overbought conditions, suggesting a potential short-term pullback may be imminent. However, the RSI did not form a bearish divergence, supporting the possibility of a continuation of the trend.

Bollinger Bands

Bollinger Bands expanded during the afternoon and early evening, coinciding with increased volatility. Price closed near the upper band, indicating strong upside momentum. The contraction seen earlier in the morning may have acted as a prelude to the breakout. If the 1.677 level is tested again, a close above it could lead to further widening of the bands, signaling higher volatility.

Volume & Turnover

Volume saw a sharp increase from 03:00 to 05:00 ET, aligning with a 1.63–1.670 price push. Turnover also spiked, confirming the price move was supported by strong buying. A divergence in volume occurred around 22:00–23:00 when price moved higher but volume dipped, suggesting some profit-taking. However, the later volume surge confirmed the validity of the bullish move.

Fibonacci Retracements

Applying Fibonacci levels to the recent swing low of 1.459 and high of 1.677, the current price of 1.670 is near the 76.4% level. The 61.8% retracement at 1.613 appears to be a potential support zone for the next 24 hours. A breakdown below 1.544 would trigger a retest of the 1.497 level, which may act as a deeper support.

Backtest Hypothesis

A potential backtest strategy could involve entering long positions when ETHFIUSDT breaks above the 20-period moving average on the 15-minute chart, confirmed by a bullish candle and a MACD crossover above zero. A stop-loss could be placed below the most recent swing low, and a take-profit target aligned with the 61.8% Fibonacci retracement level. This approach aims to leverage short-term bullish momentum while managing risk through defined stops.
