Structure & Formations

The price action formed a distinct bullish reversal pattern at the 24-hour low, with a long bearish candle followed by a large bullish engulfing candle. This occurred just above a 61.8% Fibonacci retracement level at $0.0768, which held as strong support. A doji near $0.08013 suggested indecision, and the price action from $0.078 to $0.08051 formed a small symmetrical triangle, which was decisively broken on the upside in the final hour.

Moving Averages

On the 15-minute chart, the 20-period and 50-period moving averages were in a downtrend throughout most of the 24-hour period. However, after the 15:30 ET reversal, price broke above both moving averages, with the 20-period MA crossing above the 50-period MA to form a golden cross. On a daily basis, the 50-period MA sat just above $0.083, while the 200-period MA offered a key psychological barrier around $0.0795–$0.080.

MACD & RSI

The RSI dipped below 30 in the final 1.5 hours before the reversal, indicating oversold conditions and potential for a short-term bounce. The MACD crossed above the signal line (bullish crossover) at 15:30 ET, coinciding with the breakout above $0.0805. This was confirmed by a strong positive histogram divergence that expanded through the final hour. The momentum shifted decisively to the upside during the final hour, confirming the breakout.

Bollinger Bands

Volatility expanded sharply in the last hour, with the Bollinger Bands widening from a narrow range of $0.0767–$0.078 to a wide range of $0.1012–$0.135. The price closed near the upper band at $0.10711, indicating strong buying pressure following the breakout. The contraction earlier in the day from $0.0763 to $0.078 suggested a period of consolidation, but the breakout confirmed a shift in sentiment.

Volume & Turnover

Volume was generally low throughout most of the 24-hour period but spiked dramatically in the final hour, with the last 15-minute candle recording 81,968,480 units of volume at $0.10436–$0.10711, translating to $119 million in turnover. This was 430 times the average volume of the prior 12 hours. The volume and price action were in strong alignment, with higher highs and higher volume confirming the bullish breakout.

Fibonacci Retracements

The 61.8% Fibonacci level at $0.0768 acted as critical support. Price bounced off this level and then formed a bullish engulfing pattern before breaking out above $0.0805. The key Fibonacci levels on the 15-minute chart were $0.0768 (61.8%), $0.0785 (50%), and $0.0795 (38.2%). The 15-minute swing from $0.0805 to $0.0763 saw a strong 74% retracement before the final breakout.

Backtest Hypothesis

Given the strong volume and RSI divergence in the final hour, a potential backtest strategy could involve entering a long position on a bullish engulfing pattern and RSI < 30, with a stop-loss placed below the 50-period moving average. A take-profit target could be set at the 38.2% retracement of the current swing or at the next key resistance level at $0.1143–$0.1292. This strategy would aim to capture the continuation of the breakout while managing risk with a dynamic stop-loss.
