为什么我会得到这个错误？(QuantConnect算法)
为什么我会得到这个错误？(QuantConnect算法)
提问于 2018-07-17 01:20:27
我刚刚开始使用QuantConnect，但我对Python语言理解得相当好，至少我是这么认为的。这是我的代码的重要部分：
def Initialize(self):
# Set the cash we'd like to use for our backtest
# This is ignored in live trading
self.SetCash(5000)
# Start and end dates for the backtest.
# These are ignored in live trading.
self.SetStartDate(2015,1,1)
self.SetEndDate(2018,1,1)
# Set Brokerage model to load OANDA fee structure.
self.SetBrokerageModel(BrokerageName.OandaBrokerage)
# Add assets you'd like to see
# self.eurusd = self.AddForex("EURUSD", Resolution.Minute).Symbol
self.usdjpy = self.AddForex("USDJPY", Resolution.Minute).Symbol
# self.eurjpy = self.AddForex("EURJPY", Resolution.Minute).Symbol
def OnData(self, slice):
rsi = self.RSI("USDJPY", 14, MovingAverageType.Simple)
if rsi > 72:
self.SetHoldings("USDJPY", 1)
if rsi < 28:
self.SetHoldings("USDJPY", 1)这是我得到的错误：
Runtime Error: TypeError : Cannot get managed object
at OnData in main.py:line 36
TypeError : Cannot get managed object堆栈跟踪：

System.Object.CallSite.Target(System.Runtime.CompilerServices.Closure,System.Runtime.CompilerServices.CallSite,object,QuantConnect.Data.Slice)我试图修改我创建变量'rsi‘的方式，但似乎什么都不起作用。谁能告诉我我哪里做错了？

与处理其他属性一样，您需要使用self将其设置为实例变量。
self.rsi = self.RSI(...)..。
if self.rsi > 72:或者，只需将定义移动到OnData方法中。
