Selling for a tax loss

As we approached June 30 last year, there were plenty of holders selling down to post a loss to offset their gains. However this year it will be different as we are at a high since May 16. I believe the only one selling is the same one following the same pattern they have for a while now. Let it run until 11 am then load the sell 2,3 and four pips over the price. Surely as we have buyers outweighing sellers for a little while now, they will eventually have to change tactics. I'm a nobody retail holder with 2 million shares but I'm not selling and if I had extra cash I'd be a buyer. Most shorters are now buyers so it's all good.
Just some happy thoughts I had in the spa with a few beers
