A bearish trend unfolded as price failed to hold key resistance levels and broke below critical support.

Structure & Formations

Price action formed a bearish engulfing pattern after 22:45 ET, confirming a breakdown from the 0.4729–0.4733 resistance cluster. A long lower shadow at 0.4705–0.4715 suggests rejection at this level. The most significant support was tested at 0.4552, where a bullish rejection candle formed, indicating a possible short-term floor. A falling wedge pattern was visible from 0.4659–0.4738, which resolved bearishly with a 0.4503 low.

Moving Averages

The 20-period and 50-period moving averages on the 15-minute chart crossed below key swing lows, reinforcing the bearish momentum. On the daily chart, price remains below the 50, 100, and 200-day SMAs, indicating a strong bearish bias in the broader trend.

MACD & RSI

MACD remained in negative territory for most of the 24-hour period, with bearish divergence between price and the histogram intensifying after 00:00 ET. RSI dropped below 30 during the final 4 hours, reaching an intraday low of 27.63, suggesting oversold conditions. However, RSI failed to show strong bullish divergence, pointing to a potential bounce rather than a reversal.

Bollinger Bands

Bollinger Bands narrowed significantly between 00:00 and 01:00 ET, signaling a pre-breakout consolidation phase. Price broke below the lower band at 0.4659, confirming bearish momentum. The bands have since widened, indicating higher volatility. Price remains well within the lower half of the bands, with the 0.4594–0.4604 range acting as a short-term support.

Volume & Turnover

Volume spiked during the breakdown at 0.4705–0.4711, with over 30,000 contracts traded, confirming the move lower. However, as price approached the 0.4552 level, volume thinned, suggesting a potential exhaustion of bearish momentum. Turnover was highest during the 04:00–06:00 ET period, coinciding with a sharp selloff and confirming the strength of the move.

Fibonacci Retracements

On the 15-minute chart, the key 61.8% retracement level of the 0.4705–0.4729 swing was tested at 0.4716 but failed to hold. On the daily chart, the 61.8% retracement of the 0.4738–0.4503 move lies at 0.4632, a level that could act as a potential short-term floor if the 0.4552 level fails.

Backtest Hypothesis

Given the bearish divergence in RSI and MACD, combined with a key breakdown at 0.4705–0.4711, a short-bias backtesting strategy could be constructed using a stop below the 0.4729 resistance and a target at 0.4503. The use of Bollinger Band contractions as a trigger for entries may improve entry timing, while Fibonacci levels (0.4552 and 0.4632) offer strategic exit points for risk control. This setup could be tested over prior 48-hour periods to assess consistency in volatile environments.
