How do you implement the z-score normalization in the pre-processing progress? #15

Thanks for your nice paper and codes. I am a little confused about the z-score normalization in the pre-processiong progress. Did you implement it independently for each feature (40 features in total)? e.g. for feature "AskPrice5", you collect all "AskPrice5" in the past 5 days to calculate mean and std? If so, the original order of price levels may be destroyed after z-score normalization.
