How it works
net edge = (sell − buy)/buy − feeA − feeB
profit = size × net edge
Worked example
Buy at $64,800, sell at $65,100: a 0.463% spread. After 0.2% total fees the edge is 0.263%, worth $13.15 on $5,000, if both fills land.
FAQ
Why do visible spreads persist?
Transfer time and risk. Moving coins between venues takes minutes to hours, and the spread usually closes faster than the withdrawal clears.
What eats arbitrage profit besides fees?
Slippage on both legs, withdrawal fees, and price movement mid-transfer. Serious arbs pre-fund both venues to skip the transfer entirely.
