The Bot of No Trade

Every morning prior to 10am a sale order for a small amount appears at the bid price.

But as the opening bell nears the order is slowly wound back in size until it disappears completely prior to trading commencing.

I am not sure what purpose it serves but I suppose it creates an illusion that someone is thinking about selling at the bid and this may encourage others to do the same.

So I suppose this can be interpreted as a heartening sign that someone is interested in PGI enough to play these shenanigans to try to get as many shares, even if it is in dribs and drabs, as possible at the lowest price possible.
