Strategi ini melaksanakan modul had masa berdasarkan strategi purata bergerak berganda asal untuk mengawal masa permulaan strategi. Modul had masa dapat menguruskan masa berjalan strategi dengan berkesan dan mengurangkan risiko perdagangan dalam keadaan pasaran yang tidak menguntungkan.
Strategi ini menghasilkan isyarat perdagangan menggunakan MA pantas dan perlahan. MA pantas mempunyai tempoh 14 hari dan MA perlahan mempunyai tempoh 21 hari. Isyarat beli dihasilkan apabila MA pantas melintasi di atas MA perlahan. Isyarat jual dihasilkan apabila MA pantas melintasi di bawah MA perlahan.
Strategi ini juga menggabungkan pilihan pembalikan perdagangan untuk membalikkan arah perdagangan asal.
Modul had masa membandingkan masa semasa dengan masa permulaan yang dikonfigurasi menggunakan cap masa, mengembalikan benar atau salah untuk mengawal sama ada strategi bermula atau tidak. Tahun permulaan, bulan, hari, jam dan minit perlu ditetapkan. Strategi hanya akan bermula apabila masa semasa melebihi masa permulaan yang dikonfigurasi.
Mengoptimumkan tempoh MA boleh mengurangkan kekerapan perdagangan. Waktu permulaan juga harus ditetapkan secara rasional untuk mengelakkan peluang yang hilang. Akhirnya, pilih dengan teliti sama ada untuk membalikkan isyarat berdasarkan keadaan pasaran.
Strategi ini menjana isyarat perdagangan menggunakan MAs berganda dan mengawal masa berjalan dengan modul had masa, dengan berkesan menangkap trend sambil mengelakkan keadaan pasaran yang tidak menguntungkan. Penambahbaikan lanjut boleh dibuat melalui penyesuaian parameter, modul stop loss, penjanaan isyarat silang aset, dll. untuk mengurangkan kekerapan perdagangan sambil meningkatkan kestabilan dan keuntungan setiap perdagangan.
