No open-market purchases or sales by insiders in the filings read so far. Grants, option exercises and the shares withheld for tax are under All transactions.

From Form 4 filings with the SEC, which a company’s officers, directors and owners of more than 10% must file within two business days of a trade. Value is shares times the price filed, which is often an average across several trades that day. “On a preset plan” means the filing says the trade was made under a Rule 10b5-1 plan, set up in advance and run on a schedule. An amendment that repeats an earlier filing’s line is counted once.
