Does not forecast last day available on data?

[avilarenan]

Hello! Greetings from brazil!

First of all, thanks for the awesome work and for sharing the code!

I just realized that in line 23 of file curateData.py there is a -1:
new_df = new_df.iloc[n_steps:-1, :]

Just tried to run without this -1, this way we use the last window of data to forecast the last point of data available and everything seems to work just fine. But I am using another data source, I did not test against you original data source.
new_df = new_df.iloc[n_steps:, :]

Any reason for using the -1?

Thanks in advance!
