interpretation of cross correlation between 2 signals?

Dear Matlab users,

in my way to seek the uncertainty level between two signals.

I performed a cross correlation between the 2 signals and I obtained the folowing plot

then I performed the dtw function to calculate the distance and it was 720

can I say that the data from the two signals are correlated, and what is the meaning of the value obtained using dtw, and how I can proceed further with uncertainty investigation.

I would highly apreciate your feedback
