Strategi backtest Band nombor perdana menilai trend pasaran dengan mengenal pasti nombor perdana tertinggi dan terendah di sekitar harga dan merangka kedua-dua siri nombor perdana ini sebagai band.
Risiko boleh dielakkan dengan menyesuaikan parameter dengan betul, menggabungkan dengan penunjuk lain, dll.
Strategi uji balik band nombor perdana secara keseluruhan adalah strategi yang sangat inovatif dengan nilai praktikal. Ia menggunakan ciri-ciri nombor perdana untuk menangkap rawak pasaran sambil juga mempertimbangkan ketinggalan harga dalam mengenal pasti trend, sangat berharga untuk penyelidikan. Langkah seterusnya adalah untuk mengoptimumkan dari aspek meningkatkan kualiti isyarat, memperluaskan jenis nombor rawak, pengoptimuman automatik, dll. untuk menjadikan kesan strategi lebih luar biasa.
