Cara kerjanya: Strategi tren silang sederhana menjadi panjang ketika tren cepat melintasi tren lambat, dan/atau menjadi pendek ketika tren cepat melintasi di bawah tren lambat. Opsi untuk kedua arah tren dibangun ke dalam templat strategi ini. Skrip juga dikodekan dengan cara yang memungkinkan Anda untuk mengaktifkan/memodifikasi pengaturan piramida dan skala ke posisi dari waktu ke waktu setelah tren telah melintasi.
Kasus penggunaan: Jenis strategi ini dapat mengurangi volatilitas laba dan dapat membantu menghindari penurunan pasar yang besar. Misalnya, mereka yang menjalankan strategi lintas tren jangka panjang mungkin tidak menyadari setengah dari penurunan pasar yang sedang lesu atau jatuh pada tahun 2002, 2008, 2010, dst. Namun, di tahun-tahun lain, mereka mungkin keluar dari pasar dari waktu ke waktu pada titik-titik yang tidak menguntungkan yang tidak berakhir dengan penurunan, atau terkadang pasar bergerak menyamping. Beberapa juga menggunakannya untuk mengurangi volatilitas dan kemudian menambahkan leverage untuk mencoba mengalahkan pembelian/penahanan aset dasar dalam ambang batas penurunan yang dapat diterima.
