Thanks a lot! 但是好像还不行：
double A = MarketInfo("EURUSD",MODE_BID);
double B = MarketInfo("USDJPY",MODE_BID);
double C = MarketInfo("EURJPY",MODE_BID);
init()
{
A=MarketInfo("EURUSD",MODE_BID);
B=MarketInfo("USDJPY",MODE_BID);
C=MarketInfo("EURJPY",MODE_BID);
} int start()
{.....}
这里列举了其中几个错误。
'MarketInfo' - initialization expected C:\Program Files\MetaTrader - North Finance\experts\final.mq4 (2, 12)
'(' - comma or semicolon expected C:\Program Files\MetaTrader - North Finance\experts\final.mq4
')' - unbalanced right parenthesis C:\Program Files\MetaTrader - North Finance\experts\final.

'A' - variable not defined C:\Program Files\MetaTrader - North Finance\experts\final. mq4 (9, 4)
......
到底哪里出问题了呢？？
Sorry. This was mistape.
double A; double B; double C; init() { A = MarketInfo("EURUSD",MODE_BID); B = MarketInfo("USDJPY",MODE_BID); C = MarketInfo("EURJPY",MODE_BID); } int start() { ... }
MarketInfo is function, only can use it inside codes( init, start et,), not used at declare region.

您好！
请问我下面的定义对吗?为什么编写的时候提示错误：'MarketInfo' - initialization expected C:\Program Files\MetaTrader - North Finance\experts\final. mq4 (1, 19)
'A' - variable not defined C:\Program Files\MetaTrader - North Finance\experts\final. mq4 (11, 12)
extern double A = MarketInfo("EURUSD",MODE_BID);
extern double B = MarketInfo("USDJPY",MODE_BID);
extern double C = MarketInfo("EURJPY",MODE_BID);
int start()

}
