Profit number Position type, refer to {@var/POSITION_DIRECTION/PD_LONG PD_LONG}, {@var/POSITION_DIRECTION/PD_SHORT PD_SHORT}.

The exchange.GetPositions() function returns an array of Positions or an empty array. For cryptocurrency futures, it is important to note that the Position structure array returned by the exchange.GetPositions() function. For the FrozenAmount, Profit, and Margin attributes in the position data structure, as the data provided by the exchange is not uniform, the GetPositions() interface, the definition of the data returned by the exchange object may be different. For example, some exchanges have no position freeze data in the position data, so the FrozenAmount is 0. If you need to calculate certain data, you can use the original data in the Info attribute to calculate and analysis.
