Strategi ini menggabungkan dua penunjuk momentum untuk mendedahkan lebih banyak peluang perdagangan. Penunjuk pertama adalah strategi pembalikan osilator stokastik yang dicadangkan dalam buku Ulf Jensen. Penunjuk kedua adalah harga sintetik John Ehlers. Strategi ini mengambil kedudukan apabila kedua-dua penunjuk memberikan isyarat beli atau jual serentak.
Logik di sebalik pembalikan osilator stokastik adalah: pergi panjang apabila penutupan lebih rendah daripada penutupan sebelumnya selama 2 hari berturut-turut dan garis cepat berada di atas garis perlahan; pergi pendek apabila penutupan lebih tinggi daripada penutupan sebelumnya selama 2 hari berturut-turut dan garis pantas berada di bawah garis perlahan.
Harga sintetik yang diturunkan (DSP) dikira sebagai:
DSP = EMA ((HL/2, kitaran 0.25) - EMA ((HL/2, kitaran 0.5)
di mana HL/2 adalah titik tengah tinggi dan rendah, EMA kitaran 0.25 mewakili trend jangka pendek dan EMA kitaran 0.5 mewakili trend jangka panjang. DSP menunjukkan penyimpangan harga dari kitaran dominan. Beli apabila DSP melintasi ambang dan jual apabila melintasi di bawah.
Strategi ini menggabungkan isyarat dari kedua-dua penunjuk. Ia hanya memasuki kedudukan apabila kedua-dua penunjuk memberikan isyarat serentak.
Strategi ini menggabungkan dua penunjuk momentum yang berbeza dan meningkatkan kualiti isyarat melalui penapisan berganda sambil mengekalkan kekerapan perdagangan dan mengawal risiko.
