By enabling the custom filter in the indicator settings, you will notice you have the ability to filter out zones using an external indicator such as an RSI. Maybe you only want zones to be calculated/drawn when the RSI is overbought or oversold, or maybe you only want the zones to calculate/draw if the Supertrend is green or red. The list of possible filters that you can implement is too many to count. Feel free to play around with the indicator however you like, and configure something that you find to be the most useful for your trading.
On top of everything listed above, the indicator has pre-programmed built-in alertconditions so that you can potentially automate trading, or get a notification to your cell phone when a zone is being touched/broken.
