Combined BB & New SuperTrend Strategy

Explanation
Bollinger Bands Section:
A customizable moving average (with multiple options) calculates the basis, upper, and lower bands. These are plotted on the chart with a filled area between them.

New SuperTrend Section:
The new SuperTrend code is integrated after renaming its variables (prefixed with st_) to avoid conflicts. This section calculates ATR-based stop levels, determines the trend direction, and generates buy/sell signals when the trend reverses. Optional labels and visual fills are also provided.

Trading Logic:
When a bullish SuperTrend signal occurs (transition from bearish to bullish), the script closes any short position and enters a long position. Conversely, when a bearish signal occurs, it closes the long position and enters a short. Additionally, if the price touches the Bollinger Bands (upper for longs, lower for shorts), the respective positions are exited.

This combined script should now compile without errors and use your new SuperTrend indicator for trade signals while retaining the Bollinger Bands exit conditions. Let me know if you need further modifications or explanations!
