Strategi ini disebut
Logikanya adalah:
Hitung jumlah up close bar dalam 20 bar terakhir, dan persentase p periode up dalam 100 bar terakhir.
Sambungkan jumlah periode dan probabilitas p ke dalam fungsi distribusi binomial untuk menghitung fungsi distribusi kumulatif (CDF).
Menerapkan EMA 10 hari dan 20 hari ke CDF. Ketika EMA cepat melintasi di atas EMA lambat, ini menandakan kemungkinan tinggi reversi harga ekstrem, menghasilkan sinyal beli.
Ketika EMA cepat melintasi di bawah EMA lambat, harga mungkin mencapai puncak dalam jangka pendek, menghasilkan sinyal jual di sini.
Keuntungan dari strategi ini adalah memperkirakan waktu pembalikan harga ekstrim melalui metode probabilitas.
Kesimpulannya, teknik statistik membantu mengungkap pola perilaku harga secara obyektif.
