@RobertWilson2017,thanks for the input! An impulse bar is when you get a good long bar, that closes near the highs on strong volume. Often there is a gap between the impulse bar and the preceding bar. It signals decisive price action, which many of the best moves start with. A good example of an impulse bar here is from the first hour of trading today on $AMZN. I was looking for one to breach the neckline I have drawn but it didn't happen, instead it put up a bunch of short indecisive looking bars. Still looks like like a good trade imho.
