A stationary wave is a wave formed by the superposition of two progressive waves of the same frequency and amplitude travelling in opposite directions.

A stationary wave as anodes and nodes, nodes are points of zero amplitude and antinodes are points of maximum amplitude

The nodes form because at that point the amplitudes of the two waves are moving in opposite directions and thus cancel, so particles don't oscillate.
Antinodes form because at that point the amplitudes add together, the amplitude of the peak is double that of one of the original progressive waves.

I couldn't explain it better as your words did. You did not forget a single detail.

thanks! that's a perfect explanation, I understand it now!
