Strategi ini menggunakan rel atas dan bawah Bollinger Bands untuk melaksanakan stop loss dinamik. Ia pergi pendek apabila harga memecahkan melalui rel atas dan pergi panjang apabila harga memecahkan melalui rel bawah. dan ia menetapkan stop loss dinamik untuk mengesan pergerakan harga.
Inti strategi ini terletak pada rel atas dan bawah Bollinger Bands. rel tengah adalah purata bergerak n hari. rel atas adalah rel tengah + kPengecualian standard n hari. Rel bawah adalah rel tengah − kn hari deviasi standard. Apabila harga melantun dari rel bawah, pergi panjang. Apabila harga jatuh kembali dari rel atas, pergi pendek. Pada masa yang sama, strategi menetapkan titik stop loss dan secara dinamik menyesuaikannya semasa pergerakan harga untuk menetapkan titik mengambil keuntungan untuk melaksanakan kawalan risiko yang berhati-hati.
Strategi ini menggunakan atribut regresi Bollinger Bands
