On a betting exchange you can take a position on the market and afterwards close the position in such a way that your profit is guaranteed regardless of the outcome of the event. Closing a position is not necessarily done to achieve profit but it can also be performed to minimize loss. Some of the betting exchanges make the so called "cash out" option available to you with the click of a button and you do not have to go into details of the operation because the software of the exchange does everything for you. However not all exchanges offer that feature and this is where this tool comes into use.
If you have taken a lay position, you are required to provide its details (lay odds and amount) as well as the back odds at which you aim to close the position. Respectively if you have taken a back position, you are required to provide its details and the lay odds at which you aim to close the position. In order to achieve profit, the value of the back odds should be greater than the value of the lay odds. The calculator outputs the amount with which you have to perform the final operation in order to have one and the same profit or loss in all possible cases.
