Hi can someone help me converting this pinescript to a ninjatrader script?
Code:
//@version=5
strategy("Steven Primo Bollinger Band", overlay=true, default_qty_type=strategy.percent_of_equity, default_qty_value=100, process_orders_on_close=true, max_labels_count=500)

// Inputs

var bollingerLength = input.int(20, "Bollinger length", minval=3, group=S_BOLLINGER, inline=S_BOLLINGER)
var mult = input.float(0.382, "Standard deviation", minval=0.0, step=0.1, group=S_BOLLINGER, inline=S_BOLLINGER)
var orderDirection = input.string(LONG, "Order direction", options=[LONG, SHORT, ALL], group=S_SETUP)
var useTrailingStop = input.bool(false, "Use trailing stop", group=S_SETUP)
