Each dot is one insider's purchases on one day. The dot's area follows the amount: the largest purchase here gets the largest dot. Hold the pointer over a dot to see the date and the amount.

A cross is one insider's sales on one day. People sell to pay tax, to cash in share awards or to hold less of one company, so a sale says less than a purchase does. When someone bought and sold on the same day, the cross sits beside the dot. The totals are under “Purchases against sales” below.

The band marks the stretch with the most different buyers: at most 15 days long and at least two people. Here it is 21 May – 28 May, with 2 insiders. Only the strongest stretch is marked. Several people deciding the same thing is harder to explain by one person's private reasons, but insiders often buy together just after a closed period ends, so compare it with the grey weekly bars.

A taller bar is a week in which more companies disclosed insider purchases. The purple bar is the week of the band above: 259 companies, number 1 of the last 26 weeks. If that week was a peak anyway, buying together is less special than it looks.
