Inti strategi yang diterangkan dalam artikel ini adalah strategi baki dinamik, iaitu, nilai mata wang baki sentiasa sama dengan nilai mata wang penilaian. Walau bagaimanapun, logik strategi sangat mudah apabila ia direka sebagai pesanan pra-terhad. Tujuan utama menulis strategi ini adalah untuk menunjukkan semua aspek reka bentuk strategi.
Strategy Logic Encapsulation Mengekap logik strategi dengan beberapa data dan pembolehubah tag pada masa berjalan (dikekap sebagai objek).
Kod untuk permulaan pemprosesan strategi Maklumat akaun awal direkodkan dalam pelaksanaan awal untuk pengiraan keuntungan. Pada masa pelaksanaan awal, anda boleh memilih sama ada untuk memulihkan data mengikut parameter.
Kod untuk pemprosesan interaksi strategi Pemprosesan interaktif sederhana jeda dan meneruskan direka.
Kod untuk pengiraan keuntungan strategi Kaedah pengiraan standard mata wang digunakan untuk mengira keuntungan.
Mekanisme kelangsungan data utama dalam strategi Merancang mekanisme untuk memulihkan data.
Kod untuk memaparkan maklumat pemprosesan strategi Paparan data bar status.
