X-Margin Mark to Market API
X-Margin provides free live market data that allows traders to mark to market any BTC option, future, or forward within a given range. X-Margin has interpolated live market data from Deribit’s public API, to create a 3D Volatility Surface that lines up with the current mark prices as much as possible, and also uses futures prices and synthetics of options contracts to create a forward curve.
Therefore a client can price any option or forward within that range. This is one example of an OTC mark to market feed, and we can customize any asset class, any fitting methodology and data source (see below for a 3D volatility surface example).
