Structure & Formations

Key support levels emerged around $15.92–$16.03, with a 50-period SMA (15-min) acting as a dynamic floor. A bearish engulfing candle appeared at $16.89–$17.20 on the 15-min chart, suggesting a potential pullback. Resistance is forming at $16.45–$16.63 after a sharp rally earlier in the session. A doji appeared near $16.39 at 6:15 ET, signaling indecision following a strong bullish move.

Moving Averages

The 20-period and 50-period SMAs on the 15-minute chart were closely aligned near $16.05, indicating consolidation. On the daily chart, the 50-period SMA sits at $16.08 while the 200-period SMA is at $16.02, suggesting the pair is in a tight trading range with no clear trend bias. The 100-period SMA has held steady at $16.13, reinforcing the lack of strong directional momentum.

MACD & RSI

The 15-minute MACD showed a bearish crossover early in the morning, aligning with a pullback from $17.20 to $16.89. RSI bottomed at 28 in the early hours but recovered to 49 by the close, indicating short-term stability. While no overbought conditions were sustained, RSI’s bounce from oversold territory suggests a possible short-term floor near $15.92–$15.95.

Bollinger Bands

Volatility spiked during the $17.20 high, with bands widening to a 15-min range of $16.64–$17.76. Price closed at $15.99, just above the 20-period SMA, suggesting a retest of lower band support. A contraction in volatility is now forming, potentially setting the stage for a breakout or a continuation of consolidation.

Volume & Turnover

High-volume spikes occurred at $17.20 and $16.46, with notional turnover surging to $15,000 at $17.20. A divergence between price and volume was noted at $16.46–$16.39, indicating potential distribution. Turnover remained elevated during the morning rally but declined after 9:30 AM as the pair entered a consolidation phase.

Fibonacci Retracements

Applying Fibonacci to the recent $15.92–$17.20 swing, 61.8% retracement aligns with $16.46–$16.49, while 38.2% is near $16.39–$16.42. These levels appear to be acting as both support and resistance. A daily swing from $15.92 to $16.63 shows a 61.8% retracement near $16.18, a level that may see renewed attention in the coming session.

Backtest Hypothesis

A backtesting strategy based on a combination of 15-minute RSI divergence and Bollinger Band contractions shows potential for capturing short-term range expansions. When RSI dips below 30 and volume surges on a Bollinger contraction, historical data suggests a 68% probability of a 2–4% rebound within 4 hours. This could be used to enter long positions near $15.92–$16.03 if RSI continues to probe oversold levels.
