Structure & Formations

The candlestick chart shows a mix of bullish and bearish signals. A notable bearish engulfing pattern appeared around 19:30–20:00 ET, suggesting a shift from bullish to bearish momentum. A strong rejection at the 31.0–31.1 resistance level during the afternoon, followed by a rebound off the 30.6–30.7 support, indicates a possible consolidation phase. A doji formed near 30.61–30.64, hinting at indecision and potential reversal. These patterns suggest the market is in a tug-of-war between buyers and sellers, with neither side gaining a clear upper hand.

Moving Averages and Volatility

On the 15-minute chart, the 20-period and 50-period moving averages crossed multiple times, reflecting rapid price swings and a non-trending environment. The 20-period MA currently sits above the 50-period MA, forming a weakly bullish bias for the short term. On the daily chart, the 50-period MA is slightly below the 200-period MA, indicating a neutral to mildly bearish trend for the longer term. The widening gap in Bollinger Bands points to increasing volatility, with the price frequently testing the lower band, a potential sign of oversold conditions.

Momentum and Reversal Signals

The RSI fluctuated between overbought and oversold levels during the day, with a brief overbought peak at 31.13 and a sharp drop to near-oversold at 30.28. This suggests the price may be correcting after extended moves in both directions. The MACD histogram shows a mix of bullish and bearish momentum, with divergences appearing in the afternoon, especially during the selloff. These signals indicate the market could be due for a reversal or consolidation in the near term.

Volume and Turnover Insights

Volume surged during key price swings, with the largest spikes occurring around 15:00–15:30 ET and again at 14:45–15:00 ET, when the price dropped sharply. These high-volume candles correlate with price rejections and strong trend changes. Turnover also reflected this volatility, with a sharp drop observed during consolidation phases. Price-volume divergence occurred during the morning pullback, where volume did not confirm further price movement, signaling potential exhaustion of momentum in either direction.

Fibonacci Retracements

Applying Fibonacci levels to the most recent 15-minute swing (from 31.13 to 30.28), the 61.8% retracement is at 30.66, which aligns closely with the current price. This suggests a potential support level for the next few hours. On the daily chart, the 50% and 61.8% retracement levels fall at 30.66 and 30.54, respectively. These levels could serve as key price anchors for the next 24 hours, depending on the direction of the next swing.

Backtest Hypothesis

A potential backtesting strategy would focus on identifying and acting on “Bullish Engulfing” patterns within the SEIJPY pair. Given the complexity of the chart and the mixed momentum indicators, a strategy based on confirming such patterns with high-volume entry and stop-loss placements at key Fibonacci or Bollinger Band levels could be viable. However, due to the ticker identification issue in the backtesting system, a clean and consistent data source must be confirmed first. Once the ticker symbol is validated—whether through a recognized exchange code or an alternative pair—a precise backtest can be constructed and executed to evaluate the pattern’s effectiveness under current volatility conditions.
