Inti dari strategi yang dijelaskan dalam artikel ini adalah strategi saldo dinamis, yaitu nilai mata uang saldo selalu sama dengan nilai mata uang penilaian. Namun, logika strategi sangat sederhana ketika dirancang sebagai pre-pending order. Tujuan utama menulis strategi ini adalah untuk menunjukkan semua aspek desain strategi.
Strategy Logic Encapsulation Mengkapsulkan logika strategi dengan beberapa data dan variabel tag pada runtime (dikapsulkan sebagai objek).
Kode untuk inisialisasi pemrosesan strategi Informasi akun awal dicatat dalam run awal untuk perhitungan keuntungan. Pada runtime awal, Anda dapat memilih apakah akan mengembalikan data sesuai dengan parameter.
Kode untuk pemrosesan interaksi strategi Proses interaktif sederhana dari jeda dan melanjutkan dirancang.
Kode untuk perhitungan keuntungan strategi Metode perhitungan standar mata uang digunakan untuk menghitung keuntungan.
Mekanisme persistensi data kunci dalam strategi Merancang mekanisme untuk memulihkan data.
Kode untuk menampilkan informasi pemrosesan strategi Tampilan data bar status.
