Chart please...?

Look in a chart, locate a pin bar, and examine what followed.

Any time period is applicable, although I generally play 1 hour and up.

After a pin bar appears, how often does that sew fill back in all of the way to the top or bottom?

Engulfings on a 1 hour chart are often pin bars on a 4 hour chart. So you take up the ride, using an eye on the ride back down. It is going to often tell you to the pip where a change is likely, and a exit point.
