@SensibleandHourly just had the same thing. A million short-term sales. Many wash sales. The wannabe Wall Street Genius ended up losing about the same amount as your client. If they spent that much time actually working, instead of flushing money down the toilet, while trying to be the Wolf of Wall Street, then they would be better off. Also make sure you charge for your time involved. Don't do it for free. If they don't like it, let them $%#@ off. Just my opinion.
