交易分析：

• GetProfitTrades() : 返回盈利交易的数量。
• GetLossTrades() : 返回亏损交易的数量。
• GetTotalTrades() : 返回执行的总交易数。
• GetShortTrades() : 返回卖空交易的数量。
• GetLongTrades() : 返回多头交易的数量。
• GetWinLossRatio() : 返回盈利与亏损交易的比例。
• GetAverageProfitTrade() : 返回每笔盈利交易的平均利润。
• GetAverageLossTrade() : 返回每笔亏损交易的平均亏损。
• GetROI() : 计算投资回报率。
• GetLargestProfitTrade() : 返回单笔交易的最大利润。
• GetLargestLossTrade() : 返回单笔交易的最大亏损。
• GetShortTradesWon() : 返回成功卖空交易的百分比。
• GetLongTradesWon() : 返回成功多头交易的百分比。

交易收益数组：

• GetTradeProfitArray(double &outputArray[]) : 返回每笔交易的收益数组，以便进行详细的交易结果分析。

示例代码如下：

// Import the external MyTradingHistory.ex5 module
#import "MyTradingHistory.ex5"
   void UpdateValues(void);                         // Updates the trading data from the MyTradingHistory library. EXECUTE THIS EVERY TIME YOU WANT TO UPDATE THE VALUES, e.g. after closing a trade or before retreiving the value for the first time.
   void GetTradeProfitArray(double &outputArray[]); // Retrieves an array of profits from closed trades
   double GetAccountBalance(void);                 // Returns the current account balance
   double GetProfit(void);                         // Returns the net profit
   double GetDeposit(void);                        // Returns the total deposit amount
   double GetWithdrawal(void);                     // Returns the total withdrawal amount
   int GetProfitTrades(void);                      // Returns the number of profitable trades
   int GetLossTrades(void);                        // Returns the number of loss trades
   int GetTotalTrades(void);                       // Returns the total number of trades
   int GetShortTrades(void);                       // Returns the number of short trades
   int GetLongTrades(void);                        // Returns the number of long trades
   double GetWinLossRatio(void);                   // Returns the win-to-loss ratio
   double GetAverageProfitTrade(void);             // Returns the average profit per trade
   double GetAverageLossTrade(void);               // Returns the average loss per trade
   double GetROI(void);                            // Returns the return on investment (ROI)
   double GetLargestProfitTrade(void);             // Returns the largest profit from a single trade
   double GetLargestLossTrade(void);               // Returns the largest loss from a single trade
   double GetShortTradesWon(void);                 // Returns the percentage of short trades won
   double GetLongTradesWon(void);                  // Returns the percentage of long trades won

                   "Short Trades Won: " + DoubleToString(GetShortTradesWon(), 2) + "%\n" +
                   "Long Trades Won: " + DoubleToString(GetLongTradesWon(), 2) + "%\n";

   // Add trade profit array data to the output
   output += "Trade Profit Array (First 5 Trades): ";
   double tradeProfitArray[]; // Declare an array to store trade profit data
   GetTradeProfitArray(tradeProfitArray); // Fetch trade profit data

   // Loop through the first 5 trades and append their profit values to the output
   for (int i = 0; i < MathMin(5, ArraySize(tradeProfitArray)); i++)

   }

   // Append the last trade's profit value
   output += "...\nLast Closed Trade: ";
   int size = ArraySize(tradeProfitArray); // Get the size of the trade profit array
