Here is a QuantBook research template on indicators. We can use this template to select and display indicators. We can also annotate trading signals on the charts so as to have a better understanding of how the indicators actually work.

However, it is very likely to come across overfitting problems when using indicators. Here is an example which might be likely to have an overfitting problem.

Hi,
Â
I've been looking to join the indicator information with the data. this post seems to be doing that. however when I'm running the exact same code after I clode, I'm getting an error. It seems a real nuissance that the types we're working with are not dataframes. Could I get any help with this? thanks

Hi Jens,
This old template needs some updates to work properly. First we need to change the way we're defining df2. Instead of constructing df2 with df.close, let's create a blank dataframe and populate it.
# Put asset and indicators into a new dataframe
df2 = pd.DataFrame()
# Suppose we want to predict tomorrow's return
df2['nextdayreturn'] = df.close.shift(-1)/df.close
Next, we'll also need to update a column's name.
df2['macd>0'] = (df2.signal > 0)*1.0needs to be updated to
df2['macd>0'] = (df2.movingaverageconvergencedivergence > 0)*1.0Best

Hi Rahul,
I'm unable to get your code to run. When I clone and try I get

Hi Ju,
To resolve the first error explained above, we need to replace
AddReference("QuantConnect.Jupyter") from QuantConnect.Jupyter import *with
AddReference("QuantConnect.Research") from QuantConnect.Research import *After making this change, the last cell in the notebook still throws an error. To resolve this one, we just need to decrease `plotto` from
plotto = "2015-6-15"to
plotto = "2015-6-6"See the attached notebook for reference.
Best,
Derek Melchin
