Long-only strategy

[riodda]

Hi, i would like to know if it's possible to create a long only strategy without short sell on position close.

Sure, you just call Strategy.position.close().

Yes, this was my first taught, but i have

AttributeError: 'property' object has no attribute 'close' error.
I probably haven't got yet the librari structure.

I have a buy label from 0-1 and when the label goes over 0.5 i whant the stretegy to buy, if falls below to sell but not short.

`class RF_Label(Strategy):

def init(self):
    self.rf_buy = self.I(RF_buy, self.data.RF_Label, self.data.PP)
    super().init()
    
def next(self):
    if not self.position:  # not in the market
        if crossover(self.data.RF_Label,self.data.thersold):
            self.buy()
    else:
        if crossover(self.data.thersold,self.data.RF_Label):
            Strategy.position.close()`

Was actually quite easy, self.position.close().....

Yeah, "Strategy" in Strategy.position.close() just stands for the reference class. The method/accessors are to be called on an instance of said class, here self. 👍
