Structure & Formations

The 24-hour OHLCV data reveals multiple key price levels. The critical support level at $15.22 was tested multiple times, particularly during the early hours, and held firm. A bullish engulfing pattern formed at 14:30 ET, indicating a potential shift in momentum. The price then rallied to a 24-hour high of $16.13, forming a large bullish candle that could mark a short-term resistance zone. The absence of bearish confirmation after this move suggests a possible continuation of the upward trend in the near term.

Supports and Resistances

Key support levels were identified at $15.22, $15.18, and $15.13, all of which were tested and held. Resistance levels developed at $15.31, $15.49, and $15.60. The most recent resistance at $16.13 appears to be a psychological barrier, with price showing signs of consolidation after reaching it. A break above this level could trigger further gains.

Candlestick Patterns

The 15-minute chart showed a series of bullish patterns, including a 14:30 ET bullish engulfing pattern and a 09:30 ET morning star. These suggest a shift in sentiment from bearish to bullish during the session. A potential bearish harami was also observed near $15.53 in the early hours, but it was negated by subsequent price action.

Moving Averages

On the 15-minute chart, the 20-period and 50-period SMAs provided dynamic support for most of the session, especially during the rally from $15.22 to $15.33. The 50-period SMA crossed above the 20-period SMA in the early hours, indicating a bullish crossover. On the daily chart, the 50-period and 100-period SMAs were closely aligned, while the 200-period SMA remained below the price action, confirming the bullish bias.

Trend Confirmation

The price closed above both the 50-period and 20-period SMAs, confirming a medium-term bullish trend. A continued rise in the 50-period SMA could signal the start of a stronger uptrend. A retest of the 100-period SMA at $15.45 could provide a potential consolidation zone before the next move.

MACD & RSI

The 15-minute MACD showed a strong bullish crossover early in the session, with the histogram expanding as the price moved higher. RSI reached overbought territory, peaking near 75 at $16.13, indicating a potential pullback. However, the absence of a bearish MACD divergence and the bullish momentum in volume suggest that the overbought condition may not trigger a significant correction.

Momentum and Divergence

While the RSI showed signs of overbought conditions, there was no bearish divergence with price or volume to confirm a reversal. In fact, volume and notional turnover increased during the final hours, confirming the strength of the move. A bearish divergence may develop if price fails to close above $16.13 and RSI drops below 50 without a corresponding increase in volume.

Bollinger Bands

The 20-period Bollinger Bands showed a period of contraction near $15.22, followed by a sharp expansion as the price moved higher. Price closed near the upper band, indicating strong bullish momentum. The width of the bands increased significantly during the afternoon, reflecting heightened volatility. A move outside the upper band could confirm a breakout.

Volatility Insights

The widening bands suggest that volatility is likely to remain elevated, at least in the short term. A consolidation period near the upper band could provide an opportunity for a retest of key resistance levels. A breakdown below the middle band would be a bearish signal, though this appears unlikely based on current momentum.

Volume & Turnover

Volume spiked dramatically during the afternoon and evening hours, particularly between 14:30 and 17:00 ET, as the price moved from $15.44 to $16.13. Notional turnover increased in tandem, confirming the strength of the move. A divergence between price and turnover occurred briefly near $15.53, but it was negated by the strong volume in the final hours. The final hour saw a volume spike that confirmed the bullish engulfing pattern.

Fibonacci Retracements

Applying Fibonacci retracements to the recent swing from $15.06 to $16.13, the 38.2% level is at $15.73, the 50% level is at $15.59, and the 61.8% level is at $15.46. The price currently sits near $16.03, slightly above the 50% level, suggesting that it is in overbought territory. A pullback to the 50% or 61.8% levels could be expected in the next 24–48 hours, with the potential for a retest of the 15.59 level.

Backtest Hypothesis

The backtesting strategy is based on a combination of bullish engulfing patterns, RSI, and volume spikes to identify potential breakout opportunities. The bullish engulfing pattern at 14:30 ET was accompanied by a volume surge and a RSI move into overbought territory, confirming the breakout. This aligns with the backtesting hypothesis, which looks for high-volume bullish reversal patterns at key support levels. A successful trade would have been triggered at this pattern with a stop-loss below $15.22 and a take-profit at $16.03 or higher. The strategy also emphasizes confirmation via volume and RSI divergence to avoid false breakouts.
