// *** USE AT YOUR OWN RISK ***
// - Nothing is perfect, and all decisions by you are on your own head. And stuff.
//
// Description:
//  - It's RSI versus a Simple Moving Average.. Not sure it really needs much more description.
//  - Should not repaint - Automatically offsets by 1 bar if anything other than "open" selected as RSI source.

// === INPUTS ===

rsiLength   = input(defval = 8, title = "RSI Length", minval = 1)
// sma
maLength    = input(defval = 34, title = "MA Period", minval = 1)
// invert trade direction
tradeInvert = input(defval = false, title = "Invert Trade Direction?")
// risk management
