How do you state that two vectors $\vec{A}$ and $\vec{B}$ have the same direction? I know the symbol $| |$ shows that they are parallel, but is there a symbol like this that shows that the direction of the vectors are equal. I think you would call the two vectors collinear. Is there a symbol to show that two vectors are collinear?

You can say (1,2,3) and (2,4,6) are parallel.
As $ \vec{a} = k \vec{b}$
Edit - Difference between parallel and collinear
If two parallel vectors have angle = 0 between them that is both are in same direction but collinear vector lie in same plane they may be parallel or anti parallel that is angle = 180.
Two vectors $\mathbf v$ and $\mathbf w$ are in the same direction if and only if $$\frac{\mathbf{v}}{v}\cdot\frac{\mathbf{w}}{w}=1$$
One of the many ways your can rephrase this is $\mathbf{\hat v}=\mathbf{\hat w}$. You are right that they are scalar multiples.
