Introduction 

The CoinFLEX Rate Index is applicable to all of CoinFLEX’s perpetual contracts and represents the $ funding payment on a long 1 BTC (or 1 ETH etc……) perpetual futures position on CoinFLEX made every 8 hours to CoinFLEX’s perpetual contract holders.  For example see below some sample data for the BTC rate index.

The CoinFLEX Rate Futures is a derivative contract with the respective coin Rate Index acting as the underlying.  It allows the contract holder to hedge against any funding exposure they might have from holding a perpetual contract in the same coin.

Rate Futures Mark Price 

 

Current Week: If the Rate Index is partially known for the contract week because the current date/time is after the beginning of the contract week then the mark price is:

• Sum of all the known Rate Index for the contract week so far + coin spread price from now until the expiry of the contract week as determined by the exchange.

 

Future Weeks: If the Rate index is not known yet for the delivery week because the current date/time is before the beginning of the contract week then the mark price is:

• The price spread between the coin futures price of the contract week and the prior contract week as determined by the exchange.

 

Current Month: If the Rate Index is partially known for the contract month because the current date/time is after the beginning of the contract month then the mark price is:

• Sum of all the known Rate Index for the contract month so far + coin spread price from now until the expiry of the contract month as determined by the exchange.

 

Future Months: If the Rate index is not known yet for the delivery month because the current date/time is before the beginning of the contract month then the mark price is:

• The price spread between the coin futures price of the contract month and the prior contract month as determined by the exchange.
