Because fees apply on both open and close. Even a perfect round-trip costs you money. Break-even is the price where fees are fully covered.
Does leverage affect break-even price?
Leverage does not change the break-even price directly. Only fees and side (long/short) determine it. Leverage affects how much margin you need.
What assumptions and edge cases does this calculator use?
