Strategi ini berdasarkan dua penunjuk yang terkenal: Indeks Kekuatan Relatif (RSI) dan Purata Bergerak Bertimbang (WMA). Ia mengenal pasti trend pasaran dan mengikuti arahnya. RSI menilai tahap overbought / oversold, WMA menentukan trend harga. Gabungan kedua-duanya dapat menapis isyarat yang tidak relevan dengan berkesan dan meningkatkan keuntungan. Ini adalah strategi jangka menengah / panjang, ditambah dengan kaedah pengurusan wang untuk menyesuaikan saiz kedudukan berdasarkan keuntungan / kerugian.
RSI adalah salah satu penunjuk overbought / oversold yang paling terkenal. Rumusnya adalah:
$$RSI = 100 - \frac{100}{1+\frac{AvgGain}{AvgLoss}}$$
Di mana AvgGain adalah purata hari yang ditutup di atas terbuka selama x hari yang lalu, AvgLoss adalah purata nilai mutlak hari yang ditutup di bawah terbuka selama x hari yang lalu.
Strategi ini menetapkan tempoh RSI sebagai 20 untuk menilai trend. RSI di atas 60 menghasilkan isyarat panjang, RSI di bawah 40 menghasilkan isyarat pendek.
Berbanding dengan SMA, WMA memberi berat kepada harga baru-baru ini lebih berat.
$$WMA = \frac{\sum_{i=1}^n w_i x_i}{\sum_{i=1}^n w_i}$
Di mana w adalah berat, w berkembang secara eksponensial dengan meningkatkan i. Strategi ini menggunakan formula berat berikut:
$$w = \begin{cases} 100/(4+(n-4)1.3), & i <= 3 \ 1.3w, & i > 3 kes
Iaitu berat adalah sama dalam 3 hari terakhir, dan meningkat 1.3 kali setiap 1 hari ke belakang.
Panjang WMA dalam strategi ini ialah 20.
Isyarat panjang: RSI > 60 dan ROC 20 hari WMA < -1 Isyarat pendek: RSI < 40 dan ROC 20 hari WMA > 1
Di mana ROC 20 hari WMA dikira sebagai:
$$ROC = (WMA_{hari ini}/WMA_{20_days_ago} - 1) \ kali 100$$
Strategi ini menggabungkan RSI dan WMA untuk menentukan arah trend, bertujuan untuk mendapat keuntungan daripada trend utama dalam jangka sederhana / panjang. Pengurusan wang dan mengambil keuntungan strategi juga digunakan untuk mengawal risiko. Ia mempunyai nilai praktikal tetapi tetapan parameter dan mekanisme hentian kerugian memerlukan ujian dan pengoptimuman berterusan untuk hasil yang lebih baik. Pelabur harus menilai keadaan, campur tangan secara manual jika perlu, dan memastikan risiko yang boleh dikawal.
