Strategi ini adalah sistem perdagangan komprehensif yang menggabungkan sistem dua garis rata, analisis indikator lemah relatif ((RSI) dan kekuatan relatif ((RS)). Strategi ini mewujudkan mekanisme keputusan perdagangan pelbagai dimensi dengan pengesahan trend di atas rata-rata bergerak indeks pada 13 dan 21 hari ((EMA) dan pengesahan isyarat perdagangan di atas RSI dan nilai RS terhadap indeks asas. Strategi ini juga merangkumi mekanisme kawalan risiko dan penghakiman masuk semula berdasarkan 52 minggu tertinggi.
Strategi menggunakan mekanisme pengesahan pelbagai isyarat:
Strategi ini membina sistem perdagangan yang komprehensif dengan menggabungkan analisis teknikal dan analisis kekuatan relatif. Mekanisme pengesahan isyarat berbilang dan sistem kawalan risiko menjadikannya sangat praktikal. Dengan arah pengoptimuman yang disyorkan, strategi ini masih mempunyai ruang untuk peningkatan lebih lanjut. Pelaksanaan strategi yang berjaya memerlukan pedagang mempunyai pemahaman yang mendalam tentang pasaran dan melakukan penyesuaian parameter yang sesuai mengikut ciri-ciri jenis perdagangan tertentu.
