MPLX Surges 3.05% on Bullish Candlestick Reversal Key Support Holds as Moving Averages Confirm Uptrend

Mplx (MPLX) closed the most recent session with a 3.05% increase to $56.83, indicating a strong bullish reversal after recent volatility. This surge follows a prior session’s 0.99% decline, suggesting short-term momentum may have shifted. The candlestick pattern reveals a potential bullish engulfing formation, where a large white candle (2/13) dominates the previous smaller black candle (2/12). Key support levels can be identified at $55.14 (2/12 low) and $53.81 (2/9 low), while resistance appears at $56.17 (2/12 high) and $56.46 (2/6 high). The price has tested the $55.14 support twice, suggesting it could hold in the near term.

Candlestick Theory

The recent price action shows a bullish breakout above the descending channel formed by the 2/9 to 2/13 highs. A strong green candle on 2/13 with a long lower wick (low of $55.33 vs. close of $56.83) confirms buying pressure. Key confluence is seen at $55.14, where the 50-day moving average (calculated at $55.40) and prior support align. A breakdown below $55.14 may trigger a test of the next support at $54.36 (2/10 low).

Moving Average Theory

The 50-day MA (55.40) is above the 200-day MA (54.50), confirming an uptrend. The 100-day MA (55.00) acts as a dynamic support. The price currently sits above all three MAs, suggesting continued bullish momentum. However, the 50-day MA’s slope has flattened recently, indicating weakening upward momentum. A close below the 50-day MA may signal a bearish crossover, but the 200-day MA remains a critical baseline.

MACD & KDJ Indicators
The MACD line (12-period EMA minus 26-period EMA) crossed above the signal line on 2/13, confirming a bullish crossover. The histogram has widened, indicating strengthening momentum. The KDJ stochastic oscillator shows K at 85 and D at 78, suggesting the price is approaching overbought territory. However, a divergence exists: while the price made a higher high on 2/13, the K line failed to surpass its previous peak (K=90 on 2/5), hinting at potential exhaustion.

Bollinger Bands

The 20-period Bollinger Bands have widened from a 2/10 contraction, with the price now near the upper band ($57.12). This suggests heightened volatility and a possible short-term overbought condition. A pullback to the 20-day SMA ($55.50) could indicate consolidation, but a break above the upper band may extend the rally.

Volume-Price Relationship

The recent 3.05% gain was accompanied by a surge in volume (2.35M shares) compared to the prior session’s 6.91M shares. This volume surge validates the price strength, as strong volume on a bullish reversal increases the probability of a sustained move. However, the 2/12 decline also had high volume, creating a mixed signal. Divergence in volume (lower volume on 2/13 compared to 2/12) may indicate weakening conviction.

Relative Strength Index (RSI)

The 14-period RSI stands at 62, rising from 55 on 2/12. While not yet overbought (>70), the upward trajectory suggests momentum. A close above 70 would trigger a cautionary overbought warning, but the current level supports the bullish case. A drop below 50 would signal weakening momentum.

Fibonacci Retracement

Applying Fibonacci levels to the 1/30 ($55.41–56.38) and 2/6 ($55.93–56.46) ranges, key retracement levels at 38.2% ($55.80) and 61.8% ($55.45) align with recent support areas. The price’s current level ($56.83) is above the 23.6% retracement ($56.10), suggesting a potential extension of the rally. A breakdown to the 50% level ($55.60) could trigger a test of the 61.8% level.

Concluding Observations

Confluence is strongest at $55.14–55.45, where support levels, moving averages, and Fibonacci retracements align. While the MACD and bullish candlestick pattern support an uptrend, the KDJ divergence and RSI proximity to overbought territory suggest caution. A close above $57.12 (Bollinger upper band) may extend the rally, but a breakdown below $55.14 could trigger a retest of $54.36. Volume validation of the recent surge adds credibility, though mixed signals in volume trends warrant monitoring. The 50-day MA and 50% Fibonacci level ($55.60) will be critical near-term benchmarks.
