Strategi ini mengenal pasti peluang pembalikan selepas situasi overbought atau oversold berdasarkan penunjuk RSI. Ia akan memantau perbezaan antara harga dan RSI selepas RSI memasuki zon overbought atau oversold untuk menentukan kemungkinan pembalikan masa depan.
Strategi ini menggunakan penunjuk RSI untuk menentukan situasi overbought dan oversold di pasaran. Selepas RSI memasuki zon overbought atau oversold yang telah ditetapkan, ia akan mula memantau perbezaan pembalikan.
Khususnya, jika RSI memasuki zon overbought, ia akan memantau sama ada harga terus meningkat (membentuk paras terendah yang lebih tinggi) sementara RSI membentuk paras terendah yang lebih rendah - perbezaan menaik biasa; atau harga membentuk paras terendah yang lebih rendah dan RSI membentuk paras terendah yang lebih tinggi
Begitu juga, jika RSI memasuki zon oversold, ia akan memantau sama ada harga terus jatuh (membentuk paras tertinggi yang lebih rendah) sementara RSI membentuk paras tertinggi yang lebih tinggi
Apabila isyarat pembalikan di atas dikesan, kedudukan panjang atau pendek akan diambil mengikut parameter yang dikonfigurasikan.
Kelebihan terbesar strategi ini adalah dapat mengenal pasti situasi pasaran yang melampau di mana kebarangkalian pembalikan tinggi dan margin keuntungan untuk operasi pembalikan adalah besar.
Di samping itu, strategi ini merangkumi pemantauan untuk perbezaan biasa dan tersembunyi supaya lebih banyak peluang pembalikan dapat dikenal pasti dan peluang baik tidak akan dilewatkan kerana situasi satu kali.
Risiko terbesar yang dihadapi oleh strategi ini adalah situasi overbought atau oversold yang lebih melampau, yang dipanggil
Selain itu, jika parameter tidak ditetapkan dengan betul dan terdapat kesilapan dalam menilai situasi overbought dan oversold, kesilapan boleh berlaku dengan mudah.
Cara menangani ini adalah dengan menetapkan had atas dan bawah untuk zon overbought dan oversold untuk mengelakkan situasi yang terlalu melampau.
Strategi ini boleh dioptimumkan dalam aspek berikut:
Menggabungkan penunjuk lain untuk menentukan keadaan overbought dan oversold untuk mengelakkan bergantung hanya pada RSI
Tambah logik untuk mengenal pasti penyatuan sebelum pecah apabila kebarangkalian pembalikan lebih tinggi
Mengoptimumkan tetapan sasaran keuntungan selepas pembalikan untuk membolehkan saiz kedudukan yang lebih saintifik
Menggunakan kaedah pembelajaran mesin pada tahun-tahun kebelakangan data sejarah untuk mengoptimumkan parameter secara automatik
Meningkatkan pengoptimuman logik stop loss, contohnya mengambil keuntungan yang tepat pada masanya, stop loss yang tercetak, stop loss yang tertinggal, dll.
Kesimpulannya, ini adalah strategi arbitrase statistik biasa. Ia cuba untuk menangkap peluang apabila pasaran bangkit dari situasi yang melampau kembali ke keseimbangan. Berbanding dengan strategi yang mengikuti trend, ia mempunyai kadar kemenangan dan keuntungan yang lebih tinggi tetapi juga menghadapi risiko yang lebih besar. Dengan pengoptimuman parameter dan kawalan risiko, strategi jenis ini dapat memperoleh keuntungan dengan mantap.
