The flow runs one way only: 1 insider bought (1 purchase) and nobody sold on the market. The amount is not disclosed for 1 filing. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. On the buying side, the filings list 1 major shareholder among the declarants.
