为什么Buylimit总是不能成功？

[fenzhengrou]

如下代码：
ticket = OrderSend(Symbol(), OP_BUYLIMIT, lotsize, LowPrice, 2,
LowPrice-lostpoint,
LowPrice+profittarget,
"", MagicNumber, 0, MediumBlue);
if(ticket<0)
Print("time=", TimeToStr(Time[0]), ", ticket=", ticket, ", BuyLimitPrice=",LowPrice,
", Ask=", Ask, ", err=", GetLastError(),
", stop=", LowPrice-lostpoint,
", profit=", LowPrice+profittarget,
", lotsize=", lotsize);

结果总是无法交易：
