Pada bila-bila masa, anda akan melihat sehingga 4 garis trend dalam skrip ini.
▶ Garis trend menyambung dengan titik tertinggi dalam keadaan trend menaik ▶ Trendline menyambung pivot low dalam keadaan uptrend ▶ Garis trend menyambung dengan paras tertinggi dalam keadaan penurunan ▶ Trendline menyambung pivot low dalam keadaan downtrend
Garis lama akan kekal sehingga yang baru datang melalui jenis yang sama. oleh itu, anda masih akan dapat melihat garis trend uptrending tinggi dan rendah untuk instrumen downtrending yang dicipta jauh kembali!! Juga, garis trend baru menggantikan yang lama hanya jika mereka lebih kuat (menyambung kepada lebih banyak pivot dengan kurang lebihan)
