Pada setiap titik waktu, Anda akan melihat hingga 4 garis tren dalam skrip ini.
▶ Trendline bergabung dengan pivot high dalam kondisi uptrend ▶ Trendline bergabung dengan pivot low dalam kondisi uptrend ▶ Trendline bergabung dengan pivot high dalam kondisi downtrend ▶ Trendline bergabung dengan pivot low dalam kondisi downtrend
Garis yang lebih tua akan tetap sampai yang baru datang melalui jenis yang sama. oleh karena itu, Anda masih akan dapat melihat garis tren naik dan rendah untuk instrumen downtrend yang dibuat jauh ke belakang!! Juga, garis tren baru menggantikan yang lama hanya jika mereka lebih kuat (terhubung ke lebih banyak pivot dengan lebih sedikit overflow)
