HistoryPositionInfo version 2 – library MetaTrader 5

Version 1.0: HistoryPositionInfo.

New in version 2:

The GetProfitInPoints function is still available, but it is recommended to use the new GetProfit function:

   bool              GetProfit(double &profit_in_points,
                               double &commission,
                               double &swap,
                               double &profit_in_money);

The GetProfit function returns the following information about a position, in addition to the profit in points: commission, swap and profit in money.

The CHistoryPositionInfo class is designed for getting the profit of a position in points, commission, swap and profit in money based on the trading history.
