Structure & Formations

The candlestick structure revealed a strong bullish bias, with a series of higher highs and higher lows forming after 19:00 ET. A bearish engulfing pattern emerged at 19:15 ET, but it was quickly reversed as buyers stepped in. A long upper shadow at 19:45 ET hinted at initial resistance, but the price surged past this level by the morning session. A bullish flag pattern developed between 19:45 ET and 06:00 ET, followed by a breakout and a strong continuation into the afternoon.

Moving Averages

On the 15-minute chart, the 20-period and 50-period moving averages are both bullish and aligned with the trend, with price staying above the 50 MA for most of the day. On the daily chart, price held above the 50- and 100-period MAs, while the 200 MA remains a potential long-term support at ~635. The trend is intact with no significant divergence observed.

MACD & RSI

The MACD crossed above the signal line around 05:45 ET, confirming the bullish momentum that developed during the overnight session. The histogram remained positive for most of the day, especially after the 08:15 ET breakout. RSI rose from mid-50s to peak near 65, indicating strong buying pressure without entering overbought territory. The oscillator pulled back slightly in the late afternoon but maintained above 50, suggesting that momentum remains intact.

Bollinger Bands

Volatility expanded during the day, especially after 08:15 ET, with Bollinger Bands widening from a narrow contraction earlier in the morning. Price closed near the upper band, which is a strong signal of bullish momentum. The mid-band was at ~648.5, just above the close price, indicating that the trend could continue if buyers maintain pressure. A test of the upper band tomorrow could confirm a potential breakout continuation.

Volume & Turnover

Volume surged significantly during the morning session, especially between 08:15 ET and 08:45 ET, coinciding with the key breakout. Notional turnover spiked during this time, confirming the move rather than signaling divergence. A smaller but notable volume bar appeared at 13:45 ET, coinciding with a sharp pullback and confirming short-term profit-taking. The overall volume profile suggests strong conviction in the bullish trend, with no bearish divergence evident.

Fibonacci Retracements

Applying Fibonacci retracement to the recent 15-minute swing from the low of 637.8 to the high of 652.0, key levels at 38.2% (~645.1) and 61.8% (~648.0) were both tested and respected. The 61.8% level (~648.0) was the last major retracement before the price surged past it, indicating strong support. On the daily chart, the 38.2% retracement from the prior week's range lies at ~641.5, a potential near-term support.

Backtest Hypothesis

A potential backtesting strategy could involve using the breakout of the 61.8% Fibonacci level as an entry trigger, with a stop placed just below the 648.0 level and a target aligned with the next Fibonacci extension at ~652.5. The MACD crossover above the signal line and the sustained RSI above 50 provide additional confirmation for the trade setup. Volume confirmation on the morning breakout also strengthens the validity of the entry. This strategy could be tested on historical 15-minute data to determine its reliability in similar setups.
