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
);
