Sentiment Analysis Algorithm Pipeline

I tried to implement pipeline into a sentiment algorithm by Harrison Kinsley, using the rules from his algorithm in this post : https://www.quantopian.com/posts/seeking-feedback-on-trading-based-on-sentiment-analysis-plus-intro

It doesn't order anything so there's definitely something wrong with the algo and I can't seem to figure out what the problem is. Any help would be greatly appreciated!

#I have yet to implement these pieces:  
elif (sentiment <= -1) and (current_position > 0):  
                    order_target(s,0)  
elif (sentiment >= -1) and (current_position > 0) and s in context.shorts:  
                        order_target(s, 0)

Hi Mustafa,

If you change line 60 to if stock in context.longs.index: (and similar syntax in line 66), it should fix your problem. By default, if you check if a value is in a pandas dataframe, it will look across the column names instead of the index. I noticed you have a similar check in the bit of code that you pasted above but haven't implemented yet, so you'll likely want to add the .index there as well.
