Calculation basis
C = B × Q + buy fee (quote) + other costs
N = sell price × net quantity × (1 − sell fee rate)
Net P&L = N − C
ROI = 100 × (N − C) / C
Break-even price = ceil to increment [ C / (net quantity × (1 − sell fee rate)) ]

Buy at 100, sell at 120, quantity 2, fees 0.1% on each side: net P&L 39.56 and break-even price 100.21 (increment 0.01).
