The RSI reached overbought territory above 70 by 00:45–01:15 ET, but failed to sustain the move, hinting at potential profit-taking. The MACD crossed above the signal line around 22:15 ET, confirming bullish momentum into the overnight hours.

Volume surged to over 1.4 million during the 23:15–23:30 ET period, coinciding with the price pushing past 5.5669. Notional turnover mirrored this increase, suggesting conviction in the move. Volume then declined after 02:00 ET, while price remained in a narrow range, indicating exhaustion.

Fibonacci levels on the 5-minute chart showed support at 5.5601 (61.8%) and 5.5598 (38.2%) during the overnight pullback. On the daily chart, 5.5643 (61.8%) appears to be a key level that could be retested in the next 24 hours if the trend reverses.
