Vier Box for Amibroker (AFL)

Click a star to give your rating!
It has been observed that most of the technical anlysts are bogged down with series of indicators and hardly have time to trade. I call it “complexomenia” with “analysis & paralysis” symptom. Answer to it is viered box which gives pictoral presentatin about market direction, trend strength aon a continues basis and free us for undertaking actual trade.
Here is a screenshot of how the indicator looks:



/*
VierBox ver 0.1. Messy programming, rough plotting, barely usable :D
   ver 0.2. * Parameter VierBox per saham bisa di save. Tidak perlu lagi memakai
      Draw Rectangle. Big time saver :D
     * Plot yang lebih halus
     * fitur untuk menampilkan/menyembunyikan VierBox
     * fitur untuk menampilkan/menyembunyikan garis vertikal
     * fitur untuk menampilkan dan merubah warna VierBox (masih sangat sederhana)
     * fitur untuk merubah warna garis
     * Bagian Title akan memberikan informasi jika ada parameter yang berubah sejak
      disave dan memberi rekomendasi apa yang hrs dilakukan.
  ver 0.3. * Warna box sesuai rules pak Vier. Maap pak Vier, baru kelar sekarang . Ternyata susah juga buatnya :D
      * text di box untuk menandakan box uptrend, downtrend, stackingBox, etc.
     * Warna Outline candlestick bisa dirubah di parameter
  ver 0.3.1 * text di box untuk ExplosiveBox


Cara penggunaan: Dari Menu Parameters, Klik "RESET ALL" untuk menampilkan parameter yang telah disave
     atau
     Dari Menu Parameters, Klik "SAVE" untuk menyimpan parameter yang telah dirubah

Catatan teknis: parameter setiap saham disimpan di directory C:\amibroker\vierbox\namasaham.txt

Saran, usul dan komentar dipersilahkan.
