Introduction
For this contest you will assume the role of a derivatives trader. Your task is to execute profitable trades with other users to build up a position that is "in-the-money" when the contract expires. The trader with the highest in-the-money position at contract expiration wins.
Basics
The derivative used in this contest is a Forward contract (aka Futures contract). The value of a forward is a linear function of the price of the underlying asset. The profit or loss you make on a trade is the difference of the underlying price at termination and the price at which you executed the trade times the notional amount. If you entered into a long position then you will gain if the price difference is positive and lose if it is negative. For a short position it is the exact reverse.

Getting Started
In order to interact with the derivative contract, you first need to create your own instance of an approved account contract. This is a smart contract owned and operated by you. Its main functions are to provide an interface to the derivative contract and to hold the collateral for your positions. The amount of ether you deposit into your account contract is the maximum you can lose. Once the derivative contract has been settled, you can transfer the remaining balance out of your account contract and destroy it or continue to use it with other derivatives if you wish.

In order to participate in the contest, you need to deploy the account contract to the Ropsten test network and fund it with test ether. You can do this with your preferred tool for interacting with Ethereum-based smart contracts such as Truffle or Remix. For your convenience, a purpose-built web application is available which provides a GUI to perform most tasks. The web application can be launched from https://proderivatives.com/prod
The web application directly interacts with the blockchain using MetaMask or your local Ropsten node just as Truffle and Remix would.
The Contest
All verified account contracts registered with derivative deployed at 0x7e49ec8389335a6280fbd411d5ac704e646632a9 on the Ropsten network participate in the contest. Once registered, you can trade as much as you want to increase your chances of winning.
The contract used for the contest is a "managed forward" meaning that ProDerivatives will perform operational tasks for the benefit of all users:
Daily valuation between 16:30 and 17:00 UTC
Monitoring of collateral positions
Close-out of positions in default
Settlement within 24h after expiration
It is your responsibility to ensure that your account contracts holds sufficient collateral to cover your position and open orders. Should you fail to do that, ProDerivatives will attempt to reduce or close your position by posting offsetting orders at the price calculated by the derivative contract. The price includes a spread against your favor designed to attract traders willing to take over your position. It is more beneficial to you if you close your position yourself rather then letting the contract do it for you. On the other hand, you may be able to enter into profitable positions if you manage to pick up a close-out order from a defaulting counterparty.
Hint: The collateral requirement for a long position cannot exceed the position amount (notional * execution price). If you deposit this much collateral then there is no need to monitor the account.
After contract expiration and settlement, accounts will be ranked by the settlement amount they received.
The owners of the account contracts that receive the first, second, and third highest settlement amount are awarded ETH 1.5, 1, and 0.5, respectively. Winners will be asked to provide an Ethereum Mainnet address to receive the award.
