Darker lines indicate when 2 of the 3 Supertrends from the popular “Triple Supertrend” day trading strategy are in agreement. Lighter lines indicate when all 3 are in agreement, and an arrow will let you know when it happens. Lines and arrows can be turned on and off, so you do not need to use both. A 3rd option, an oscillator, is available for advanced users (but off by default) looking to program custom automations like entries and exits from this indicator.
