There are 3 teams and every trader will have the right to choose to become a member in any team he want. Every week, the total trading volume of the teams will be ranked by the system. The prize will be divided among the teams based on the rank (60%, 30%, 10% respectively) and the team members will also be divided based on the percentage that they contribute to the total volume of the team. Rankings and prizes are announced every Friday then traders can claim their reward immediately. Note: Total volume per team will also be calculated by week, not cumulative.
