MarcoVieira - PB+BB+SAR+Supertrend

Here’s a concise explanation in English of what your script does:
- Supertrend:
Calculates the Supertrend indicator using ATR. It plots green lines when the trend is bullish and red lines when bearish. It also shows buy/sell labels when the trend changes, and can highlight the background according to the trend. Alerts are triggered on buy, sell, or direction change.
- Pivot Boss EMAs:
Plots several exponential moving averages (20, 50, 100, 200, 400) directly on the price chart. These help visualize short-, medium-, and long-term trends.
- Bollinger Bands:
Draws Bollinger Bands (upper, lower, and basis) around price, with dynamic coloring (green if price is above the basis, red if below). The fill between bands changes color accordingly.
- Parabolic SAR:
Plots the Parabolic SAR dots above or below price, configurable with start, step, and maximum values. Dots appear gray depending on whether price is above or below the SAR.
👉 In short: this indicator combines Supertrend signals, multiple EMAs, Bollinger Bands, and Parabolic SAR into one chart to give a multi-tool view of market trend, momentum, and potential entry/exit points.
