Get the account drawdown (Absolute, Maximal and Relative)

[[Deleted]]

Hello forum, good day.

How can the account drawdown (Absolute, Maximal and Relative) be calculated in code? I found the following calculations for Absolute and Maximal DrawDown in this article, but it doesn't show how to do it in code:

 

AbsoluteDrawDown = InitialDeposit - MinimalBalance

MaximalDrawDown = Max of (Maximal Peak - next Minimal Peak) 

For the initial deposit I will try the following, but I don't know if it will work:

//+------------------------------------------------------------------+
//| Get deposits function                                            |
//+------------------------------------------------------------------+
double fnGetDeposits()
  {
    int    TotalHistory = OrdersHistoryTotal();
    double Deposit      = 0;

    for ( int cnt = 0; cnt < TotalHistory; cnt++ )
      {
        OrderSelect( cnt, SELECT_BY_POS, MODE_HISTORY );
        if ( ( OrderSymbol() != Symbol() || OrderMagicNumber() != MagicNumber ) && OrderType() == 6 ) Deposit += OrderProfit();
      }

    Print( "Initial deposit: ", Deposit );

    return( Deposit );
  } //--- end fnGetDeposits()

 

Your help will be much appreciated.

 

Best regards and thank you in advance,
