Ethereum Series (ETH) Guide

Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed on a blockchain without any possibility of downtime, censorship, fraud or third party interference. The project is developed by the Ethereum Foundation. The Ethereum currency is denominated by the currency code ETH and is commonly referred to as Ether. Further information about ETH and the Ethereum Project can be found here.

On BitMEX, the ETH derivative is in the form of a Futures Contract and allows traders to speculate on the future value of the Ether / Bitcoin (ETH/XBT) exchange rate. Traders need not have Ether to trade the futures contract as it only requires Bitcoin as margin.

How Are ETH Futures Quoted?

The ETH futures’ underlying is the ETH/XBT exchange rate on Poloniex as recorded in the .ETHXBT Index. The futures are quoted in Bitcoin and all margin and PNL calculations are denominated in Bitcoin.

Contract Calculations
Multiplier 1
XBT Contract Value Multiplier * Futures Price * 1 ETH
USD Contract Value XBT Contract Value * XBTUSD
PnL Calculation # Contracts * Multiplier * (Exit Price - Entry Price)

Traders who think that the price of ETH will rise will buy the futures contract. Conversely, traders who believe the price will drop will sell the futures contract.

Margin and Leverage

All margin is posted in Bitcoin, that means traders can go long or short this contract using only Bitcoin. The ETH futures contracts feature a leverage of up to 50x.

For example, to buy 50 Bitcoin worth of contracts, you will only require 1 Bitcoin of Initial Margin.


The ETH futures contracts settle on the .ETHXBT30M Index Price. Settlement will occur on the last Friday of the Settlement Month.

Trade Example

A trader wants to goes long 10 XBT of ETH futures contracts. ETHM17 (the ETH futures contract expiring in June 2017) trades at 0.0200 XBT. As the leverage is 50x, the trader only needs 0.2 XBT of margin for this trade.

The trader must buy 500 contracts: 10 XBT / (0.0200 XBT * 1).

A few days later, the price rises to 0.0250 XBT and the trader sells all their contracts.

The trader’s profit will be: 500 * 1 * (0.0250 - 0.0200) = 2.5 XBT
