NOL - Insiders Bought 1.2 Million Shares

The insiders of NOL just bought 1.2 million shares of the company on April 1st. IS it April's Fool or is it for real? I mean if they bought then the price would shoot right? But why is it that it isn't moving? Do we buy together with them or can we buy at a lower price? From the chart perspective, it is currently in a trading range and it's quite difficult to deduce the correct direction. I would suggest to wait for more confirmation signal before taking a position.
