Bollinger Bands + EMA 200 + EMA 50

This indicator combines three technical analysis tools: the Bollinger Bands (BB), and two Exponential Moving Averages (EMA) with periods of 200 and 50.

Bollinger Bands (BB): This indicator consists of three lines—the middle line being a simple moving average (SMA), and the upper and lower bands representing two standard deviations above and below the SMA. The width of the bands indicates market volatility, with wider bands signifying higher volatility and narrower bands indicating lower volatility.

Exponential Moving Averages (EMA 200 and EMA 50): The EMA is a type of moving average that gives more weight to recent prices, making it more responsive to price changes than the simple moving average. The EMA 200 is considered a long-term trend indicator, often used to identify the overall direction of the market. The EMA 50 is a medium-term trend indicator, helping to spot more immediate market trends. Crossovers between these two EMAs (such as when EMA 50 crosses above EMA 200) are commonly used as buy or sell signals, with the idea that a short-term trend shift is occurring.

By combining these three indicators, this custom Pine Script aims to give a comprehensive view of the market conditions, helping traders to understand both the volatility (via BB), the long-term market trend (via EMA 200), and the medium-term trend (via EMA 50). The interaction between the price and these indicators, along with crossovers, can be used to identify potential entry and exit points.
