Strategi pendek ini menggabungkan NR7 dan hari dalam untuk masa kemasukan.
Logikanya ialah:
Tentukan NR7, di mana julat adalah paling sempit dalam tempoh 7 hari
Mengenali hari dalaman, dengan tinggi lebih rendah daripada tinggi sebelumnya dan rendah lebih tinggi daripada rendah sebelumnya
Pada hari-hari apabila NR7 dan hari dalam bertepatan, dan menutup adalah lebih rendah daripada terbuka
Dan cerun purata mudah bergerak adalah ke bawah, pergi pendek
Tutup pendek pada hari berikutnya jika ditutup lagi lebih rendah daripada terbuka
Strategi ini memanfaatkan NR7 dan hari dalaman yang menunjukkan kesesakan.
NR7 dan pembalikan masa dalam hari
Keadaan menggabungkan untuk mengelakkan isyarat palsu
Operasi panjang/pendek pilihan
NR7 ditambah kejadian dalam hari kurang biasa
Memerlukan optimum parameter MA
PEMBALANGAN PEMBALANGAN Peluang panjang
Strategi ini pendek dengan berkesan mengenal pasti dan mengesahkan pembalikan. Tetapi kekerapan yang lebih rendah memerlukan penilaian. Penyesuaian parameter dan perdagangan panjang / pendek boleh memperluaskan strategi.

// ChartArt's Narrow Range + Inside Day Strategy (Short Only)
//
// Version 1.1
// Idea by ChartArt on Oktober 22, 2016.
//
// This short 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 short trade when the close is lower than the
// open and the slope of the simple moving average is downwards, too.
//
// The strategy exits the short trade next time the close is
// lower than the open in any of the next trading days.
//
// In addition the NR7ID can be colored (if close lower open
// colored in red, else in green) and the SMA can be drawn
// with a color based on the direction of the SMA slope.
