for example this way:

#define NotSetHERE 0.
int retCode = OrderSend( _Symbol,    // string   symbol,               // symbol
                         OP_BUY,     // int      cmd,                  // operation
                         1.0,        // double   volume,               // volume
                         Ask,        // double   price,                // price
                         10,         // int      slippage,             // slippage
                         NotSetHERE, // double   stoploss,             // stop loss
                         NotSetHERE, // double   takeprofit,           // take profit
                         "DEMO1",    // string   comment     = NULL,   // comment
                         -1,         // int      magic       = 0,      // magic number
                         0,          // datetime expiration  = 0,      // P/O expiration
                         clrRed      // color    arrow_color = clrNONE // color
                         );
