Pilihan pengisian ditambahkan di antara purata bergerak (ia dinonaktifkan secara lalai, diaktifkan dalam konfigurasi jika anda mahu), jika 2 purata berwarna hijau pengisian akan berwarna hijau, jika 2 purata berwarna merah pengisian akan berwarna merah, ini akan mengesahkan trend yang sihat jika anda menggunakan purata pantas dan perlahan, dalam kes bahawa perubahan arah purata pantas akan diisi dengan warna ungu, ini boleh menunjukkan beberapa perkara: pembetulan trend sedang dihasilkan, kemungkinan sisa harga, kemungkinan permulaan lateraliti, kemungkinan perubahan trend, apabila warna berwarna ungu pedagang perlu menganalisis konteks umum untuk dapat menentukan apa yang mungkin berlaku.

Isyarat berikut telah dicipta:

  • Ubah Arah 1-MA
  • Ubah Arah 2-MA
  • Melalui di bawah 2-Ma/1-Ma
  • Melalui di bawah 1-Ma/2-Ma
  • Melalui 2-Ma/1-Ma
  • Melalui 1-Ma/2-Ma
  • Tanduk 1-Ma/2-Ma
