Strategy Components

Indicators Used

1. Exponential Moving Averages (EMA)

   • A bullish trend is identified when the short EMA crosses above the long EMA.

2. MACD (Moving Average Convergence Divergence)

   • Measures the momentum of price movements.

   • Positive histogram suggests bullish momentum, negative histogram signals bearish conditions.

3. RSI (Relative Strength Index)

   • Provides insights into overbought and oversold conditions.

   • RSI above 50 supports a bullish trend; below 50 hints at bearishness.

4. SuperTrend

   • Tracks market direction and provides dynamic support/resistance levels.

   • Signals bullish trends when above the closing price and bearish trends when below.

5. ATR (Average True Range)

   • Used to set dynamic stop-loss levels based on market volatility.

   • Helps avoid premature exits in volatile markets.
