Unlike other perpetual swap contract platforms, such as Bitmex, whose depth comes from their own platfroms, SnapEx is a contract, its depth comes from the spot market. So the depth of the spot market is the depth of SnapEx. Although the price reference of perpetual contract comes from spot market, the price itself comes from its own exchange, so the fairness and liquidity may be very poor.
On SnapEx, the K-line weighted average shows real-time spot prices from 4 major cryptocurrency exchanges - Bitfinex、Huobi、Binance、Coinbase, ensuring that the prices that traders see on SnapEx are as fair and transparent as possible. In addition, SnapEx has 24 hours of liquidity. It's more fair and secure.
