Directors' buying and selling is stared in the individual company's "Securities Trading Policy", so read that here: https://norwoodsystems.com/wp-content/uploads/2018/01/Securities-Trading-Policy_00.pdf

The relevant bit is:

Black Out Periods means:
(a) In the five (5) business days prior to, and one (1) business day after the public
announcement of the financial results of the quarter;
(b) In the five (5) business days prior to, and one (1) business day after the public
announcement of the interim financial results;
(c) In the five (5) business days prior to, and one (1) business day after the public
announcement of the financial results of the year; and
(d) such other periods as the Company may notify from time to time, for example, where
the Company was considering a major transaction that could have a material effect
on the stock price.

Public announcements have already been made about the discussions with various entities who might partner with Norwood.
So ... the five day blackout for directors is already up! There could be an announcement at any time......
