Super Trend¶
A trend-following overlay that plots above price in a downtrend and below price in an uptrend; direction flips when price crosses the band. Built on ATR-based dynamic bands, it adapts volatility automatically.
Inputs: [high, low, close] | Options: [period, step] | Outputs: [supertrend] | Optional: [atr, tr, medprice]

Optional Outputs¶
supertrend exposes 3 optional outputs: atr, tr, medprice. Pass a boolean mask as the third argument — one bool per optional output, in order.
