        # Step 3: Market Regime Filter R
        # EXPLANATION: If the price is above the upper Bollinger Band, assign a value
        # of 1 to R. If the price is below the lower Bollinger Band, assign a value of -1 to R. Otherwise,
        # the value R stays 0.

        # the price is in the upper band, -1 when the price is in the lower band, and 0 when the price is in the
        # middle band. This is a simple way to determine the market regime based on Bollinger Bands. What is market
        # regime? Market regime is the state of the market. It can be trending, ranging, or reversing. So we are
        # using Bollinger Bands to determine the market regime. You can use other indicators to determine the market
        # regime as well. For example, you can use moving averages, RSI, MACD, etc.

        # Step 4: Volatility Adjustment V
        # EXPLANATION: Calculate the Bollinger Band width and assign it to V. The Bollinger Band width is the
        # difference between the upper and lower Bollinger Bands divided by the middle Bollinger Band. The idea is
        # that when the Bollinger Bands are wide, the market is volatile, and when the Bollinger Bands are narrow,
        # the market is less volatile. So we are using the Bollinger Band width as a measure of volatility. You can
