Thank you for the reply,
Unfortunately I did not understand clearly what you said. So as i was afraid i am not convolving in the right way over the dataset right? But in time series forecasting, i saw in every tutorial that the data should be split in windows so that you use the first n samples to predict the sample at time n+1, is the data format wrong too? Sorry for bothering, but could you tell me how should i organize my data and set the convolution parameters in order to perform the convolution correctly?
