Structure & Formations

The 15-minute candlestick pattern displayed a strong bearish trend after a brief early rally. Key resistance levels appear at 0.6316 (tested and rejected multiple times) and 0.6345 (previous high). The price found initial support at 0.6280 and later at 0.6201. A significant bearish engulfing pattern occurred around 02:30 ET (closing at 0.6280 after a high of 0.6345), followed by a long bearish candle at 03:45 ET (closing at 0.6280). This pattern suggests a continuation of the downward trend unless bulls reclaim 0.6316.

Moving Averages

On the 15-minute chart, the 20-period and 50-period moving averages have both dipped below the price, reinforcing the bearish momentum. The 50-period moving average has been acting as resistance between 0.630 and 0.6316. Longer-term moving averages (50/100/200) on the daily chart are not available, but the current trend suggests a possible shift from bullish to bearish bias.

MACD & RSI

The MACD (12, 26, 9) on the 15-minute chart crossed into negative territory, indicating bearish momentum. The RSI dropped to an oversold level of 27 near the end of the session, suggesting a potential reversal or at least a temporary bounce. However, given the bearish structure, this bounce may be short-lived. The divergence between the RSI and price was most notable after the 02:30 ET high, where price made a new low while RSI did not, a bearish sign.

Bollinger Bands

Bollinger Bands expanded significantly during the 02:30–03:30 ET session as the price moved lower. The price closed near the lower band, confirming a period of high volatility and bearish bias. The widening of the bands suggests increased uncertainty in the market and could lead to a potential range-bound consolidation or a continuation of the trend.

Volume & Turnover

Volume spiked during the 02:30–03:45 ET period, particularly with a large candle at 02:30 ET that saw 64,513.51 volume and a high of 0.6360. This was a key bearish confirmation as the price closed significantly lower. Notional turnover increased in line with volume, supporting the bearish move. A divergence between price and turnover during the 04:30–06:00 ET session suggests weakening momentum.

Fibonacci Retracements

Applying Fibonacci retracement levels to the recent swing high of 0.6360 and the swing low of 0.6201, the 61.8% level is at 0.6277. The price briefly held this level before breaking it, indicating a bearish breakout. The 38.2% level at 0.6299 was tested multiple times and failed to hold. A retest of 0.6277 could be a critical moment for short-term traders.

Backtest Hypothesis

The backtest strategy described involves identifying and entering short positions on a breakdown of the 61.8% Fibonacci level, confirmed by bearish candlestick patterns and a closing price below the 50-period moving average. Stop-loss is placed just above the nearest resistance, typically the previous swing high or the 50-period MA, and take-profit targets are set at the next Fibonacci level (38.2% or 23.6%) and the support level. Given today's action, this strategy would have entered a short near 0.6277, confirmed by the 02:30 ET candle, with a stop-loss around 0.6316 and a take-profit at 0.6201 or 0.6235. The strategy could be refined by adding volume and RSI divergence filters to avoid false breakouts, especially during periods of high volatility like the 02:30–03:45 ET window.
