The return that you can achieve in a BUX Battle is calculated as follows:

At the beginning of the Battle, your total account value (which is your Cash and the value of the amount that you invested) is taken as the starting point. When the Battle starts, we look at the absolute change in value of your account. Your return is then taken as the relative difference between your current account value and your account value at the beginning of the Battle. This difference in percent is your return. This can be both negative or positive which leads to a positive battle result or a negative battle result.

The person that can achieve the highest positive return wins the Battle.

** If at anytime during the battle period a user moves a position to the investing tab, the position will no longer count towards the user's percentage for the remainder of the battle (even if the user moves the position back to the trading tab).
