I have yet to see this in practice problems, has anyone else?
So far, DP has been previous close when the decision was made, and BP was when the market closed and the trade had yet to be completed. Schweser notes in one of the practice exam answers that:
“DP is the market price at the time the trade decision was made. Because the market was closed at the time of decision, it is used”
To be clear, I’m looking for something like :
“The market closed at $25. The next day it opened at $25.5, and then a decision was made to trade.”
