Hi there,
I am getting an error:
def OnData(self, data):
if self.sma20.Current.Value >= self.sma150.Current.Value:
if self.flag3 > 0:
if self.flag2 == 1:
self.flag2 = 0
if self._changes == None: return
for security in self._changes.RemovedSecurities:
if security.Invested:
self.Liquidate(security.Symbol)
for security in self._changes.AddedSecurities:
self.SetHoldings(security.Symbol, 0.8/float(len(self._changes.AddedSecurities)))
self._changes = None
if self.sma20.Current.Value < self.sma150.Current.Value:
if security.Invested:
self.Liquidate(security.Symbol)Runtime Error: UnboundLocalError : local variable 'security' referenced before assignment
at OnData in main.py:line 119
UnboundLocalError : local variable 'security' referenced before assignment (Open Stacktrace)
**Line 119 corresponds to "if security.Invested:"
I was wondering if someone would be able to help me out, thanks.

You need to loop through the list of securities that are supposed to be liquidated in this part:
if self.sma20.Current.Value < self.sma150.Current.Value: for secutity in list_of_securities_to_liquidate: if security.Invested: self.Liquidate(security.Symbol)Note that you have a similar case above:
for security in self._changes.RemovedSecurities: if security.Invested: self.Liquidate(security.Symbol)but with that snippet, we cannot tell which securities you want to liquidate.
If all:
if self.sma20.Current.Value < self.sma150.Current.Value: self.Liquidate()Alex Haseldine
