**Pro Tip:** For a comprehensive trading framework, try using multiple STARCHANNEL settings simultaneously. A narrower channel (1.0-1.5× ATR) can help identify minor retracements and short-term entry points, while a wider channel (2.5-3.0× ATR) can be used for major support/resistance zones and stop placement.
