KeyError: 'EMA' #27

Hi! Thank you for uploading this project.

I am having an issue running Backtest using the code in your README.md file. Using all of your original code and your example data, I receive the following error (I've edited out the traceback parts):

TypeError: 'str' object cannot be interpreted as an integer

  File "pandas\_libs\index.pyx", line 106, in pandas._libs.index.IndexEngine.get_value
  File "pandas\_libs\index.pyx", line 114, in pandas._libs.index.IndexEngine.get_value
  File "pandas\_libs\index.pyx", line 162, in pandas._libs.index.IndexEngine.get_loc
  File "pandas\_libs\hashtable_class_helper.pxi", line 1492, in pandas._libs.hashtable.PyObjectHashTable.get_item
  File "pandas\_libs\hashtable_class_helper.pxi", line 1500, in pandas._libs.hashtable.PyObjectHashTable.get_item
KeyError: 'EMA'

Am I setting up the features incorrectly or do you know why I might be receiving this error? I am running python 3.6.4 and all of the dependencies are installed and up to date, as per the versions listed in the SyntaxError issue posted.

Example data has feature columns called "X1" and "X2". I should make that more clear.
