Strategi ini mengamati tindakan harga di sekitar EMA tiga kali untuk menentukan trend dan perdagangan selepas penarikan.
Logik Strategi:
Tetapkan EMA pantas, sederhana dan perlahan, biasanya 25, 100, 200 tempoh.
Harga mencapai EMA terpantas semasa kenaikan / penurunan penurunan menunjukkan kenaikan / penurunan sementara.
Masuk panjang apabila harga melangkau EMA terpantas. Masuk pendek apabila harga melangkau EMA terpantas.
Zona beli / jual kod warna untuk intuisi visual.
Menggunakan stop loss tetap dan nisbah risiko / ganjaran untuk pengurusan risiko.
Kelebihan:
Dagangan pulsaback menikmati kadar kemenangan yang lebih tinggi.
Triple EMA mengenali trend dan mengelakkan whipsaws.
Nisbah risiko / ganjaran meningkatkan kelestarian prestasi.
Risiko:
Pengunduran panjang mungkin terlepas masa masuk terbaik.
Penyesuaian EMA diperlukan untuk sepadan dengan tempoh yang berbeza.
Hentian tetap boleh menjadi terlalu mekanikal dan memerlukan kalibrasi.
Ringkasnya, strategi ini memperdagangkan penembusan tarik balik menggunakan EMA tiga kali ganda untuk mengesan trend yang lebih luas. Kawalan risiko membantu menjana keuntungan jangka panjang yang stabil tetapi pengoptimuman parameter dan penghakiman tarik balik tetap penting.
