Помогите прописать в этот код увеличение суммы lots от суммы банка
Стратегия:
1. При балансе 100$ ставка в размере 0,1
2. При балансе 200$ и более ставка в размере 0,2
3. При балансе 300$ и более ставка в размере 0,3
**********
4. При балансе 1000$ и более ставка в размере 1,0

Я плохо разбираюсь и вообще не разбираюсь как это все сделать.
Также в настройках inputs необходимо.

Заранее благодарствую.
