Strategi Bull and Bear Power telah dibangunkan oleh Dr. Alexander Elder menggunakan penunjuk sinar Elder untuk mengukur tekanan membeli dan menjual di pasaran.
Dr. Elder menggunakan purata bergerak eksponensial 13 tempoh (EMA) untuk menunjukkan konsensus pasaran nilai. Kuasa lembu mengukur keupayaan pembeli untuk mendorong harga di atas konsensus nilai. Kuasa beruang mencerminkan keupayaan penjual untuk mendorong harga di bawah konsensus purata nilai.
Kuasa bull dikira dengan mengurangkan EMA 13 tempoh dari tinggi. Kuasa bear mengurangkan EMA 13 tempoh dari rendah.
Strategi ini menilai sentimen pasaran melalui pengiraan indikator kekuatan banteng dan beruang.
Apabila kekuatan bull lebih besar daripada ambang, ia adalah isyarat panjang. Apabila kekuatan bear lebih besar daripada ambang, ia adalah isyarat pendek. Perdagangan terbalik boleh dipilih.
Boleh menambah stop loss, mengoptimumkan tempoh purata bergerak, menggabungkan dengan penapis trend dan lain-lain
Strategi Bull and Bear Power menilai sentimen pasaran dengan mudah dan intuitif dengan parameter yang boleh dikonfigurasikan. Tetapi ia cenderung kepada isyarat palsu dan memerlukan pengoptimuman lanjut dengan trend dan stop loss. Logiknya patut dipelajari tetapi penerapan langsung memerlukan berhati-hati.
