Simple Bollinger SMA9 SMA200

This script combines Bollinger Bands with two key moving averages (SMA9 and SMA200) to provide traders with a clean and effective market overview.
The Bollinger Bands are based on a 20‑period SMA and an adjustable standard deviation to highlight volatility and potential reversal zones.
The SMA9 indicates short‑term momentum changes, while the SMA200 serves as a major long‑term trend filter.
Ideal for trend analysis, breakout strategies, and identifying overbought or oversold conditions.
