Structure & Formations

Price action displayed a deep bearish impulse followed by a strong bullish recovery, forming a potential bullish reversal pattern at the 16.73 level. Key support levels at 16.73 and 16.90 were tested, while resistance levels at 17.36 and 17.60 acted as psychological barriers. A morning engulfing pattern and a morning star hinted at a potential shift in sentiment.

Moving Averages

On the 5-minute chart, price briefly dipped below the 20-period MA but closed above the 50-period MA, suggesting short-term momentum could favor the bulls. On the daily chart, the 50-period MA appears to be acting as dynamic support, while the 200-period MA remains a key long-term reference.

MACD & RSI

The MACD crossed above the signal line during the morning rally, confirming a potential bullish shift. RSI dipped to 29 during the selloff, signaling oversold conditions, and has since risen toward the 50–60 range, suggesting a possible continuation of the rally.

Bollinger Bands

Volatility expanded sharply during the morning as price broke above the upper Bollinger Band. The band width widened, reflecting increased market activity and positioning. Price has since settled within the bands, maintaining a bullish bias.

Volume & Turnover

Volume spiked during the 07:15–08:45 ET window, coinciding with the recovery from 16.90 to 17.67. Notional turnover followed a similar pattern, confirming the strength of the rebound. A divergence between volume and price during the early morning selloff suggests caution is warranted.

Fibonacci Retracements

On the 5-minute chart, the 61.8% Fibonacci retracement of the 16.73–17.67 swing is at 17.20, which was a key consolidation level. On the daily chart, the 50% retracement of the larger move supports the 17.30–17.40 range as a potential target.

The pair appears to be consolidating within a bullish trendline, with growing momentum after an oversold correction. Traders may watch 17.68 as a key resistance, where a break could trigger further upside. However, a retest of 16.90–17.00 could challenge the recent strength if volume fails to confirm.
