Strategi ini menggabungkan purata bergerak indeks (EMA) dan indikator super trend (Supertrend) untuk menghasilkan isyarat jual beli. Isyarat beli dihasilkan apabila harga menembusi 20 hari EMA dari atas dan indikator super trend berada dalam trend menurun. Isyarat jual dihasilkan apabila harga menembusi 20 hari EMA dari bawah dan indikator super trend berada dalam trend menurun.
Strategi ini menghasilkan isyarat jual beli dengan menggabungkan EMA 20 hari dan indikator super trend untuk menangkap tingkah laku trend. Kelebihan strategi ini adalah bahawa logiknya mudah, kombinasi EMA dan indikator super trend dapat mengurangkan isyarat palsu dengan berkesan. Tetapi dalam pasaran yang bergolak, strategi ini mungkin sering diperdagangkan dan kekurangan langkah-langkah pengurusan risiko.
