Structure & Formations

The price action formed a key bearish engulfing pattern in the final hour of the session, signaling potential short-term exhaustion. A prior bullish divergence in the afternoon supported a temporary rally, forming a short-term support zone around 2130000.0. A multi-hour consolidation phase occurred near 2138000.0, which may become a pivotal resistance or support level in the near term.

Moving Averages

On the 15-minute chart, the 20-period and 50-period moving averages both trended upward during the morning hours but flattened out in the afternoon as price consolidation set in. The 50-period MA crossed above the 20-period in the morning, forming a bullish bias that eroded by midday. On the daily chart, the 50/100/200 EMA structure remained neutral, with price hovering near the 50-period line, suggesting a potential breakout scenario.

MACD & RSI

The MACD remained in positive territory during the morning and afternoon but diverged in the final hour, with a bearish crossover forming as price momentum waned. The RSI peaked at 58.2 in the early afternoon, suggesting moderate overbought conditions, but dipped to 49.7 by the close, indicating neutral momentum. The divergence between RSI and price in the latter half of the session points to a potential reversal scenario.

Bollinger Bands

Volatility expanded in the early afternoon, with the Bollinger Bands widening and price reaching the upper band. This indicated heightened buying activity but failed to sustain a breakout. By the final hour, volatility contracted and price settled near the middle band, suggesting a period of consolidation and potential resumption of trend formation.

Volume & Turnover

Volume remained moderate throughout the session, with a small spike observed in the 02:00–03:00 ET period. Turnover followed a similar pattern, peaking just before 02:30 ET but declining afterward. The lack of a significant volume spike during the final bullish move suggests that the move may not have broad institutional support, raising caution for long-term bullish bets.

Fibonacci Retracements

Applying Fibonacci retracement levels to the recent 15-minute swing from 2123762.0 to 2142876.0, key levels at 2135720.0 (38.2%) and 2132625.0 (61.8%) were tested in the afternoon. Price failed to break above the 38.2% level, reinforcing its significance as a potential resistance. Daily retracements indicated that 2140000.0 and 2130000.0 could become critical levels in the next 24 hours.

Backtest Hypothesis

The backtesting strategy described involves a mean-reversion approach based on Bollinger Band contractions and RSI divergence signals. A trade is initiated when price crosses below the middle Bollinger Band following a contraction and the RSI shows bearish divergence. Given the recent contraction and divergence observed in the final hours of the session, the strategy may have triggered a short signal. However, the subsequent price recovery suggests that this may not be the optimal time to enter a short trade unless further confirmation is provided by volume and moving average alignment.
