Interesting. Those who have the least experience seem to get this much easier and faster than those who've been at it for a while.
I asked partly because you appear to be picking up on it rather rapidly and partly to tell you that there's no time requirement. Some spend years at this, some months, some weeks. Whenever you feel that you'd like to play with entries and exits, go right ahead. If the results aren't satisfactory, you're always free to go back to observing for a while.
You mention the Wyckoff "book". Are you referring to his course? If so, I hope you're using
the original. If not, I just provided a link.
