Hey Quantopian Community,

I tried to use the Stochastic Oscillator in Pipeline for my Algo, but the problem was I didnt find any built in factor like for example for the MACD or RSI.

class FastStochasticOscillator(CustomFactor):  
    """  
    Fast Stochastic Oscillator Indicator [%K, Momentum Indicator]  
    https://wiki.timetotrade.eu/Stochastic  
    This stochastic is considered volatile, and varies a lot when used in  
    market analysis. It is recommended to use the slow stochastic oscillator  
    or a moving average of the %K [%D].  
    **Default Inputs:** :data: `zipline.pipeline.data.USEquityPricing.close`  
                        :data: `zipline.pipeline.data.USEquityPricing.low`  
                        :data: `zipline.pipeline.data.USEquityPricing.high`  
    **Default Window Length:** 14  
    Returns  
    -------  
    out: %K oscillator  
    """  
    inputs = (USEquityPricing.close, USEquityPricing.low, USEquityPricing.high)  
    window_safe = True  
    window_length = 14

    def compute(self, today, assets, out, closes, lows, highs):

        highest_highs = nanmax(highs, axis=0)  
        lowest_lows = nanmin(lows, axis=0)  
        today_closes = closes[-1]

        evaluate(  
            '((tc - ll) / (hh - ll)) * 100',  
            local_dict={  
                'tc': today_closes,  
                'll': lowest_lows,  
                'hh': highest_highs,  
            },  
            global_dict={},  
            out=out,  
        )  

I did find this Code for a Custom Factor but got quite some errors running it. Has anybody used a Stochastic Oscillator in Pipeline before?
Below you find my current Code using MACD and RSI (as an substitute for Stoch at the moment).

Help or ideas would be very much appreciated.
