Strategi ini didasarkan pada indeks persentase BB dikombinasikan dengan indikator RSI dan MFI. Strategi ini membuat keputusan panjang dan pendek dengan mendeteksi price breakout dari Bollinger Bands upper dan lower rail, bersama dengan sinyal oversold/overbought RSI dan sinyal oversold/overbought MFI.
Strategi ini terutama diterapkan pada instrumen non-trending volatilitas tinggi. Strategi ini menerapkan perdagangan trend fading melalui kombinasi saluran Bollinger dan indikator. Karakteristik risiko-pengembalian dapat dikendalikan dengan menyesuaikan parameter. Perbaikan lebih lanjut dapat dilakukan dengan memperkenalkan lebih banyak indikator dan model tambahan untuk mengoptimalkan kualitas keputusan, sehingga mencapai kinerja strategi yang lebih baik.
