刚开始学，这个代码为什么会错？求帮助
SQ_spirit:
if (rt[0].close>=iHigh(_Symbol,0,H))
{
if
(m_position.Select(_Symbol))
m_trade.PositionClose(_Symbol);
else //if(OrdersTotal()==0)
m_trade.PositionOpen(_Symbol,ORDER_TYPE_BUY,Lots,SYMBOL_BID,0,0,"Buy");
}
Error：'if'-Semicolon expected
第二个if下面缺少一对“ { } ”
if (rt[0].close>=iHigh(_Symbol,0,H))
{
if (m_position.Select(_Symbol))
m_trade.PositionClose(_Symbol);
else //if(OrdersTotal()==0)
m_trade.PositionOpen(_Symbol,ORDER_TYPE_BUY,Lots,SYMBOL_BID,0,0,"Buy");
}
Error：'if'-Semicolon expected
