Moving Averages and Momentum

On the 15-minute chart, the 20-period and 50-period moving averages crossed around 5.3485 and 5.3482, suggesting short-term equilibrium. The price oscillated around these levels, showing no clear directional bias. The MACD histogram remained neutral through the day, with no strong bullish or bearish divergences. The RSI peaked at overbought levels around 19:30 but gradually declined into neutral territory by the close, indicating a potential bearish correction.

Bollinger Bands and Volatility

The price remained within the Bollinger Band midpoints for the majority of the 24-hour period, with a few excursions near the upper and lower bands. Volatility was relatively low, with the bands contracting slightly during the early morning hours and expanding during the 5.3515 peak. The contraction suggested a potential breakout attempt, but price failed to sustain above 5.3515 and eventually retracted to the 5.3475 level.

Fibonacci Retracements and Key Levels

Fibonacci levels were applied to the recent 15-minute swing from 5.3461 to 5.3515. The 5.3482 close aligned with the 61.8% retracement level, indicating a strong support zone. The 38.2% retracement at 5.3495 and the 78.6% at 5.3475 were also notable in defining the tight consolidation pattern. These levels appear to be key for potential short-term trading setups.

Backtest Hypothesis

The backtest strategy involves entering long positions when the 15-minute MACD line crosses above the signal line, combined with RSI below 40 and a bullish engulfing candlestick pattern. Short positions are triggered when the MACD crosses below the signal line, RSI exceeds 60, and a bearish engulfing pattern is confirmed. Stops are placed at the nearest Fibonacci retracement levels, with targets set at key resistance and support. Given the consolidation observed in the 24-hour chart, the strategy may benefit from tighter stop levels and a focus on volatility-based breakout setups. This approach appears to align well with the current market structure and could serve as a viable short-term trading framework.
