The four numbers

The position exists. These are the numbers that came with it, and all four were available before it was opened.

The stop

The sweep reached 2,520, so module 38's default puts the stop just beyond that extreme, at 2,521.

From an entry of 2,512 that is 9 dollars of risk. Nothing about the day changes the price, because the stop is a reading of the chart rather than a preference.

Stop 2,521, because above it the sweep of the 2,518 high failed.

The size

Module 39's sum, on a 1,000 dollar practice account risking one percent.
