this a video I recorded with a strange spike a couple of months ago. https://www.youtube.com/watch?v=OZ4wZqlu-Fc
I suppose that if I place a 3k order in such a low liquidity market it won't get matched in under a second.
you should do the same. A video is much more informative than a screenshot. Just keep recording and every 30min or so restart recording if there's nothing interesting.
