Ellis,
We use the official Yahoo Finance opening price as a reference for the robot’s track record.
Orders should be entered at market. But it is true that actual execution may vary by a few cents in real life. For opening market prices, it is first come first served. The earliest you enter your market order, the more chances to have execution exactly at the official open price.
