标题：[求助]

 我想在逐K线模式下获得图表交易系统中信号发出那根K线的回撤率，不知道这样写对不对？
Sub MARKETDATA_AlarmPleaceOrder(Name, Order, OrderType, Action, Volume, Price, Code, Market, Account)
gethuicelv
masgout "回撤率" & ihuicelv
End Sub

sub gethuicelv(ihuicelv)
set data=marketdata.GetHistoryData("if00","zj",3,1)
ihuicelv=data.close/data.high
end sub

dim ihuicelv

Sub MARKETDATA_AlarmPleaceOrder(Name, Order, OrderType, Action, Volume, Price, Code, Market, Account)
gethuicelv
application.msgout ihuicelv
End Sub

 

sub gethuicelv()
set data=marketdata.GetHistoryData("if00","zj",3,1)
ihuicelv = data.close(data.count-1)/data.high(data.count-1)
end sub
