Price history

Why the same contract has two prices

Before you trade

Use the fee and break-even calculator to see your all-in cost, or the gap calculator to check whether this price difference survives fees. Related reading: why the price you see isn't your fill, how markets resolve, and how often the two exchanges disagree.
