// ChartArt's Narrow Range + Inside Day Strategy (Long Only)
//
// Version 1.0
// Idea by ChartArt on Oktober 16, 2016.
//
// This long only strategy determines when there is both
// a NR7 (narrow range 7, a trading day in which the range
// is narrower than any of the previous six days), plus a
// inside day (high of the current day is lower than the high
// of the previous day and the low of the current day is higher
// than the low of the previous day) both on the same trading day
// and enters a long trade when the close is larger than the
// open and the slope of the simple moving average is upwards, too.
//
// The strategy exits the long trade next time the close is
// larger than the open in any of the next trading days.
//
// In addition the NR7ID can be colored (if close large open
// colored in green, else in red) and the SMA can be drawn
// with a color based on the direction of the SMA slope.
