Unlike other perpetual swap contract platforms, such as Bitmex, whose depth comes from their own platforms, SnapEx is a contract for difference (CFD) trading platform - its depth comes from the futures market.
So the depth of the futures market is the depth of SnapEx. Although the price reference of perpetual contract comes from the futures 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 futures prices from 3 major cryptocurrency exchanges - Binance, Huobi and OKEx, 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.
