As TheBramble says, its not possible to say with 100% what will happen later today, so more realistic to identify - 1) the signal that will cause you to open a trade, and 2) the price that will cause you to exit the trade when you find it has not gone the way you expected.
What about, after price opens with gap down, 1) top of gap as price recovers, and 2) bottom of gap?
If the recovery continues this could be termed a whiplash or key reversal, depending on what happens in the day, but recovery to fill an Opening gap not always but often leads to continued rise through the day. That's how thse patterns came to be recognised and named.
