# Normalized data

I am new to this. I trained and tested my data using SVM in Matlab with the autoscale option true => the data would be normalized with unit SD. Let's say the training data have the price around 200.

During real time, let's say the price is around 300. I am wondering what is the practise in obtaining the mean and standard deviation in real time so that I could normalize the data for the model I built previously?

Thanks.
