Time series regression

[Ahmed1950S]

Hello, I'm new to programming and Fastai, because the nature of my project I had to jump into time series.
Can you help me with the following : I'm working with market Data each raw represents one minute, the "0" column is one minute log-returns and the "1" column is for 5 minutes log-returns. I want to make predictions based on 30 minutes intervals.
I followed all the steps but my learner gives me 0 accuracy. Is my window size too large ?

Is my data fitted to make 30 minute predictions ?

You have set your data to use 30 time steps of history to predict the next one. This will be done for every minute. If you want to make predictions every 30 mins, you should use a stride of 30 (default is 1).
