VWAP and the session figures are computed from the delayed intraday series on this page, so they lag the live tape and will not match a broker's real-time VWAP exactly. Turn on Prior day H/L/C, Opening range and Volume profile in the chart's Studies menu to see these levels drawn on price.

Price return only. Dividends are not reinvested, so total return on a dividend payer will be higher than shown.

What this is, and what it is not
These are SEC Form 4 filings — officers, directors and 10% owners reporting their own trades in the company's stock. Filing is due within two business days of the transaction, so this lags reality by days, and the provider adds its own lag on top.
A sale is not automatically bearish. Executives sell on scheduled 10b5-1 plans, to cover tax on vesting equity, and to diversify. Purchases with cash are generally the more informative signal, and they are far rarer.
This does not include congressional or senate trading. That comes from STOCK Act disclosures filed with the Senate eFD system and the House Clerk, which this data source does not carry.
Officer and director trades in their own stock, straight from Form 4 filings.
