Robot ini akan mempertahankan proporsi tertentu dari nilai setiap aset seperti yang Anda tetapkan. Jika Anda menetapkan nilai ETH menjadi 25% ((0.25) dari portofolio, penyimpangan menjadi 0.1, bot akan membeli menjadi 0.25 ketika rasio nilai di bawah 0.90,25 dan jual jika di atas 1,10.25, sehingga nilai ETH disimpan pada rasio tertentu. Menimbang lebih dari satu aset, Anda harus menambahkan pasangan perdagangan secara terpisah, dan rasio input seperti "0.25
