Structure & Formations

The 15-minute chart shows multiple testings of the 0.2893–0.2914 range, with a failed bullish breakout on the 2025-09-20 16:00 candle. A key support level formed around 0.2880–0.2885, with a large bearish reversal candle on 2025-09-21 09:30 confirming weakness. A doji appeared near 0.2855, indicating indecision. The 0.2846 low marks a critical support level that has so far held.

Moving Averages

On the 15-minute chart, the 20-period and 50-period moving averages crossed around 0.2890–0.2895, suggesting a potential trend reversal. The daily 50/100/200 SMA structure remains relatively flat, with the price currently below the 50-day SMA. This implies that short-term momentum is bearish, but longer-term bias remains neutral to mildly bearish.

MACD & RSI

The 15-minute MACD line crossed below the signal line during the overnight session, indicating bearish momentum. RSI oscillated between 30 and 50, signaling a potential oversold condition near 30, though price failed to follow through with a strong bounce. Divergence between RSI and price in the final hours suggests traders may be preparing for a deeper pullback or a consolidation phase.

Bollinger Bands

Price action remained within the Bollinger Bands throughout most of the 24-hour period. A brief expansion in the overnight hours saw volatility rise, with the price closing near the lower band on 2025-09-21 12:00. A potential bounce from this level is possible if volume picks up again.

Volume & Turnover

Volume surged during the 2025-09-21 09:30 candle, coinciding with a breakdown below 0.2880. Notional turnover remained elevated during the breakdown but dropped in the final hours. The divergence between price and volume suggests bearish exhaustion could be near, with a possible retest of key support levels expected in the next 24 hours.

Fibonacci Retracements

Applying Fibonacci to the 2025-09-20 16:00–2025-09-21 09:30 move, the 38.2% retrace level aligned with 0.2890, which was briefly tested. The 61.8% level is at 0.2883, where a bullish bounce could occur if buying pressure returns. Daily Fibonacci levels suggest further downside potential to 0.2841, which would mark a 61.8% retrace of the larger move from 0.2917 to 0.2846.

Backtest Hypothesis

The backtest strategy involves entering long positions when the 20-period EMA crosses above the 50-period EMA on the 15-minute chart, with a stop-loss placed at the nearest support level and a target at the 38.2% Fibonacci retrace level. Short positions are triggered when the opposite occurs, with stops placed at resistance. This strategy appears valid during consolidation phases and could benefit from the recent convergence of the 20 and 50 EMA lines near 0.2890. However, divergence in RSI and MACD suggests the need for tighter risk management and confirmation through volume increases before entering.
