Backtest Hypothesis

The recent price behavior suggests a strategy that targets the 3.599 Fibonacci retracement level as a potential short-term target following a bullish reversal pattern. A possible backtesting hypothesis would involve entering a long position at 3.585, the key support level, with a stop loss just below 3.577 and a take profit at 3.605, aligning with the 50-period moving average. The 15-minute MACD crossover and RSI divergence could be used to confirm or exit the trade. This approach assumes the continuation of bullish momentum and a lack of major macroeconomic shocks.
