Today, long stretches of time with no trades, including the last half hour. I guess they did their dirty work of knocking the share price down, then didn't want to short it down any more. Wise move on their part, since Monday's open might make shorting a catastrophically bad strategy if the Judge releases a favorable ruling for CTIX this afternoon.
