4H Bollinger Breakout Strategy

This strategy leverages Bollinger Bands on the 4-hour timeframe for long and short trades in trending or ranging markets. Entries trigger on BB breakouts with optional filters for volume, trend, and RSI. Exits occur on opposite BB crosses. Customizable for long-only, short-only, or indicator mode via code comments. Supports forex, stocks, or crypto with full equity allocation and 0.1% commission.

StdDev Multiplier (Default: 1.8): Band width control; higher for fewer signals, lower for more.

Offset (Default: 0): Shifts BB plots; typically unchanged.

Use Filters (Default: True): Applies volume, trend, RSI checks to filter signals.
